+# PHP Signify
+
+PHP library for verification of BSD Signify signature files, plus PHP and shell
+implementations of verifying extended CSIG signature files.
+
+## Use Case
+
+Drupal's auto-update and core validation work depends on access to trusted
+metadata and code assets. Because Drupal is deployed globally to diverse
+environments, our implementation should support public and private mirroring
+of data as well as validation by widely varying PHP releases and web host
+configurations. Hosts with outdated root certificates, insecure ciphers, or
+outdated TLS version support should not undermine access to these new Drupal
+features.
+
+## Why Signify?
+
+Signify is a defacto standard created by OpenBSD to validate assets using modern
+cryptography. The cryptographic foundations are entirely available in PHP's
+Sodium APIs and are available for legacy PHP versions through sodium_compat.
+Therefore, it is possible to implement Signify on every PHP version currently
+supported by current Drupal releases.
+
+Signify allows Drupal to anchor trust to on-disk keys shipped with the initial
+installation. Combined with the broad supportability of Signify's cryptography
+in PHP releases, we can establish trust on quite outdated infrastructure. This
+fits with our goal of building update features that support the long tail of
+installations.
+
+## Extending Signify
+
+OpenBSD's build and release model differs from Drupal's.
+
+First, Drupal maintains an extensive hosted build infrastructure that covers
+everything from core to arbitrary community projects. Maintaining the
+availability of these systems creates challenges for protecting the secrets, and
+we desire keeping the root of trust offline.
+
+Second, our release model isn't a compelling foundation for key rotation. Our
+major releases happen at too long of an interval for rotation. Our minor
+releases are more frequent, but users expect cross-compatibility (and requisite
+signature validation to work) across arbitrary mixes of minor releases and
+module builds. Site owners may also neglect their site across quite a few minor
+releases, making OpenBSD's model of shipping future release keys insufficient
+for maintaining continuity (without, say, shipping the next 10 keys and having
+little recourse if one of the corresponding private keys leaks).
+
+Taking a little inspiration from X.509 -- with an emphasis on little -- we've
+extended Signify to support chained signatures. We call this format CSIG.
+
+## Chaining with CSIG
+
+Our goal with CSIG is to support an offline root protected by an HSM. That HSM
+setup should periodically produce expiring signatures against the next public
+key for use within the build infrastructure.
+
+We can accomplish this using the building blocks of Signify, but we'd like to
+pack the pieces into a single file for ease of distribution and validation.
+
+Initial setup of CSIG infrastructure:
+
+1. Generate a keypair on the HSM.
+1. Export the public key and package in Signify's format.
+1. Bundle this public key with Drupal releases.
+
+Periodic key rotation on the build infrastructure:
+
+1. Generate a keypair on the build infrastructure. This can happen automatically but not be used until promoted into use by the final step.
+1. Use the HSM to sign and embed a message containing an expiration date and the build infrastructure's public key.
+1. Upload that signed message to the build infrastructure. This functions as an intermediate certificate.
+
+Generating a CSIG for a build:
+
+1. Generate a tagged (BSD-style) sha512sum of the built asset.
+1. Sign and embed the generated checksum list (to use the OpenBSD term) using the build infrastructure's secret key.
+1. Prepend the intermediate certificate.
+
+Validating an asset using a CSIG:
+
+1. Extract and validate the intermediate certificate against the root public key.
+1. Check that the intermediate certificate remains valid (today in UTC is not after the valid-through date).
+1. Extract the intermediate public key from the now-validated intermediate certificate.
+1. Extract the signed checksum list.
+1. Validate the signed checksum list against the intermediate public key.
+
+### Format of a CSIG
+
+Bold lines are annotations that do not occur in the CSIG.
+
+* **Intermediate key and its expiration**
+ * Untrusted Comment (line #1)
+ * Base64-Encoded Signature by Root Secret Key (line #2)
+ * **Message is an expiring public key, or xpub**
+ * Valid Through Date in UTC in YYYY-MM-DD Format (line #3)
+ * **Build Infrastructure Public Key in Signify Format**
+ * "Untrusted" Comment (line #4)
+ * Base64-Encoded Public Key (Build Infrastructure Key) (line #5)
+* **Message or Checksum List signed with key on lines 4-5**
+ * Untrusted Comment (line #6)
+ * Base64-Encoded Signature by Build Infrastructure Key (line #7)
+ * **Message or Checksum List**
+ * Message or Checksum List Entries (lines 8+)
+
+If there is only one checksum list entry, the result should be nine lines,
+including a blank line at the end. Each additional checksum list entry adds one
+line.
+
+A possible point of confusion is that line 4 begins with `untrusted comment`,
+but in fact it is part of the overall message signed by the Root Secret Key.
+This is done to allow easy usage of the Build Infrastructure Public Key in
+Signify format - it must necessarily begin with the bytes `untrusted comment`.
+#### Example CSIG File

+
+#### Example CLI Creation of a CSIG File
+
+For convenience, this example uses the `-n` option to disable passphrases.
+
+ $ signify -G -n -p root.pub -s root.sec
+ $ signify -G -n -p intermediate.pub -s intermediate.sec
+ $ date --utc --iso-8601 --date="+30 days" > expiration
+ $ cat expiration intermediate.pub | signify -S -e -s root.sec -m - -x intermediate.xpub.sig # xpub = expiring public key
+ $ sha512sum --tag module.zip > module-checksum-list
+ $ signify -S -e -s intermediate.sec -m module-checksum-list -x module.sig
+ $ cat intermediate.xpub.sig module.sig > module.csig
+
+#### Example CLI Validation of CSIG File
+
+Requisite files: `root.pub` `module.zip` `module.csig`
+
+ $ head --lines=5 module.csig > intermediate.xpub.sig
+ $ signify -V -e -p root.pub -m intermediate.xpub # Verifies/extracts intermediate.xpub.sig, creates intermediate.xpub
+ $ head --lines=1 intermediate.xpub # Displays valid-through date in UTC. Should be on or after the current date in UTC.
+ $ tail --lines=2 intermediate.xpub > intermediate.pub
+ $ tail --lines=+6 module.csig | signify -C -p intermediate.pub -x -

+### Version 2.0.18 - 2019-01-03
+
+* If `/dev/urandom` cannot be read on Unix-based operating systems,
+ a Exception with a specific error message will be thrown.
+* Fixed Psalm nits.
+* Updated the README to include a reference to the support contract
+ offering by Paragon Initiative Enterprises.
+
+### Version 2.0.17 - 2018-07-04
+
+* Version 2.0.16 failed Psalm checks on PHP v5.6 with Psalm v1.
+ We could not reproduce this failure locally, so we've suppressed the
+ `MissingReturnType` check (that is to say, demoted it to "info").
+
+### Version 2.0.16 - 2018-07-04
+
+* Fixed type-checking consistencies that forced us to use Psalm in
+ non-strict mode (i.e. `totallyTyped="false"`).
+* README cleanup, added a header to the Version 9.99.99 section.
+ * If you're confused by `v9.99.99` and it's causing stuff to break, see
+ [this section of the README](https://github.com/paragonie/random_compat#version-99999)
+ for the solution to your problem.
+* Trimmed down and annotated our `psalm.xml` file with explanations
+ for why each assertion is suppressed.
+
+### Version 2.0.15 - 2018-06-08
+
+* A reported, but difficult to reproduce, problem with file inclusion on
+ [some Windows machines](https://github.com/paragonie/random_compat/issues/136)
+ was fixed by [replacing `/` with `DIRECTORY_SEPARATOR`](https://github.com/paragonie/random_compat/pull/141).
+ For most users (i.e. not running Windows) this change should be of zero
+ consequence. For everyone else, it should mean random_compat magically
+ works when it didn't before.
+
+### Version 2.0.14 - 2018-06-06
+
+* Update version information.
+* Updated README with better instructions, including new information
+ about the `v9.99.99` tag.
+
+### Version 2.0.13 - 2018-06-06
+* #139 - Add `polyfill` keyword to composer.json
+* Ensure the docblocks are consistent to aid static analysis efforts in
+ other libraries; see https://github.com/paragonie/random_compat/commit/cbe0b11b78140bc62a921fec33a730fdaa6540d6
+
+### Version 2.0.12 - 2018-04-04
+
+* Minor docblock issue that's breaking Psalm downstream.
+
+### Version 2.0.11 - 2017-09-27
+
+* Minor docblock corrections.
+* Re-issuing a PHP Archive to attempt to address an issue with the Phar provided.
+ See [#134](https://github.com/paragonie/random_compat/issues/134).
+
+### Version 2.0.10 - 2017-03-13
+
+* Mcrypt can now be used on PHP < 5.3.7 if you're not on Windows.
+* Minor boyscouting changes.
+
+### Version 2.0.9 - 2017-03-03
+
+* More Psalm integration fixes.
+
+### Version 2.0.8 - 2017-03-03
+
+* Prevent function already declared error for `random_int()` caused by misusing
+ the library (really you should only ever include `lib/random.php` and never any
+ of the other files). See [#125](https://github.com/paragonie/random_compat/issues/125).
+
+### Version 2.0.6, 2.0.7 - 2017-02-27
+
+* Just updates to psalm.xml to silence false positives.
+
+### Version 2.0.5 - 2017-02-27
+
+* Run random_compat through the static analysis tool, [psalm](https://github.com/vimeo/psalm),
+ as part of our continuous integration process.
+* Minor readability enhancements ([#122](https://github.com/paragonie/random_compat/issues/122)
+ and several docblock changes).
+
+### Version 2.0.4 - 2016-11-07
+
+* Don't unnecessarily prevent `mcrypt_create_iv()` from being used.
+ See [#111](https://github.com/paragonie/random_compat/issues/111).
+
+### Version 2.0.3 - 2016-10-17
+
+* Updated `lib/error_polyfill.php` [to resolve corner cases](https://github.com/paragonie/random_compat/issues/104).
+* The README was updated to help users troubleshoot and fix insecure environments.
+* Tags will now be signed by [the GnuPG key used by the security team at Paragon Initiative Enterprises, LLC](https://paragonie.com/static/gpg-public-key.txt).
+
+### Version 2.0.2 - 2016-04-03
+
+Added a consistency check (discovered by Taylor Hornby in his
+[PHP encryption library](https://github.com/defuse/php-encryption)). It
+wasn't likely causing any trouble for us.
+
+### Version 2.0.1 - 2016-03-18
+
+Update comment in random.php
+
+### Version 2.0.0 - 2016-03-18
+
+Due to downstream errors, the OpenSSL removal now belongs in version
+2.0.0.
+
+### Version 1.3.1 - 2016-03-18
+
+* Add more possible values to `open_basedir` check.
+
+### Version 1.3.0 - 2016-03-17
+
+* Removed `openssl_random_pseudo_bytes()` entirely. If you are using
+ random_compat in PHP on a Unix-like OS but cannot access
+ `/dev/urandom`, version 1.3+ will throw an `Exception`. If you want to
+ trust OpenSSL, feel free to write your own fallback code. e.g.
+
+ ```php
+ try {
+ $bytes = random_bytes(32);
+ } catch (Exception $ex) {
+ $strong = false;
+ $bytes = openssl_random_pseudo_bytes(32, $strong);
+ if (!$strong) {
+ throw $ex;
+ }
+ }
+ ```
+
+### Version 1.2.2 - 2016-03-11
+
+* To prevent applications from hanging, if `/dev/urandom` is not
+ accessible to PHP, skip mcrypt (which just fails before giving OpenSSL
+ a chance and was morally equivalent to not offering OpenSSL at all).
+
+### Version 1.2.1 - 2016-02-29
+
+* PHP 5.6.10 - 5.6.12 will hang when mcrypt is used on Unix-based operating
+ systems ([PHP bug 69833](https://bugs.php.net/bug.php?id=69833)). If you are
+ running one of these versions, please upgrade (or make sure `/dev/urandom` is
+ readable) otherwise you're relying on OpenSSL.
+
+### Version 1.2.0 - 2016-02-05
+
+* Whitespace and other cosmetic changes
+* Added a changelog.
+* We now ship with a command line utility to build a PHP Archive from the
+ command line.
+
+ Every time we publish a new release, we will also upload a .phar
+ to Github. Our public key is signed by our GPG key.
+
+### Version 1.1.6 - 2016-01-29
+
+* Eliminate `open_basedir` warnings by detecting this configuration setting.
+ (Thanks [@oucil](https://github.com/oucil) for reporting this.)
+* Added install instructions to the README.
+* Documentation cleanup (there is, in fact, no `MCRYPT_CREATE_IV` constant, I
+ meant to write `MCRYPT_DEV_URANDOM`)
+
+### Version 1.1.5 - 2016-01-06
+
+Prevent fatal errors on platforms with older versions of libsodium.
+
+### Version 1.1.4 - 2015-12-10
+
+Thanks [@narfbg](https://github.com/narfbg) for [critiquing the previous patch](https://github.com/paragonie/random_compat/issues/79#issuecomment-163590589)
+and suggesting a fix.
+
+### Version 1.1.3 - 2015-12-09
+
+The test for COM in disabled_classes is now case-insensitive.
+
+### Version 1.1.2 - 2015-12-09
+
+Don't instantiate COM if it's a disabled class. Removes the E_WARNING on Windows.
+
+### Version 1.1.1 - 2015-11-30
+
+Fix a performance issue with `/dev/urandom` buffering.
+
+### Version 1.1.0 - 2015-11-09
+
+Fix performance issues with ancient versions of PHP on Windows, but dropped
+support for PHP < 5.4.1 without mcrypt on Windows 7+ in the process. Since this
+ is a BC break, semver dictates a minor version bump.
+
+### Version 1.0.10 - 2015-10-23
+
+* Avoid a performance killer with OpenSSL on Windows PHP 5.3.0 - 5.3.3 that was
+ affecting [WordPress users](https://core.trac.wordpress.org/ticket/34409).
+* Use `$var = null` instead of `unset($var)` to avoid triggering the garbage
+ collector and slowing things down.
+
+### Version 1.0.9 - 2015-10-20
+
+There is an outstanding issue `mcrypt_create_iv()` and PHP 7's `random_bytes()`
+on Windows reported by [@nicolas-grekas](https://github.com/nicolas-grekas) caused by `proc_open()` and environment
+variable handling (discovered by Appveyor when developing Symfony).
+
+Since the break is consistent, it's not our responsibility to fix it, but we
+should fail the same way PHP 7 will (i.e. throw an `Exception` rather than raise
+an error and then throw an `Exception`).
+
+### Version 1.0.8 - 2015-10-18
+
+* Fix usability issues with Windows (`new COM('CAPICOM.Utilities.1')` is not
+ always available).
+* You can now test all the possible drivers by running `phpunit.sh each` in the
+ `tests` directory.
+
+### Version 1.0.7 - 2015-10-16
+
+Several large integer handling bugfixes were contributed by [@oittaa](https://github.com/oittaa).
+
+### Version 1.0.6 - 2015-10-15
+
+Don't let the version number fool you, this was a pretty significant change.
+
+1. Added support for ext-libsodium, if it exists on the system. This is morally
+ equivalent to adding `getrandom(2)` support without having to expose the
+ syscall interface in PHP-land.
+2. Relaxed open_basedir restrictions. In previous versions, if open_basedir was
+ set, PHP wouldn't even try to read from `/dev/urandom`. Now it will still do
+ so if you can.
+3. Fixed integer casting inconsistencies between random_compat and PHP 7.
+4. Handle edge cases where an integer overflow turns one of the parameters into
+ a float.
+
+One change that we discussed was making `random_bytes()` and `random_int()`
+strict typed; meaning you could *only* pass integers to either function. While
+most veteran programmers are probably only doing this already (we strongly
+encourage it), it wouldn't be consistent with how these functions behave in PHP
+7. Please use these functions responsibly.
+
+We've had even more of the PHP community involved in this release; the
+contributors list has been updated. If I forgot anybody, I promise you it's not
+because your contributions (either code or ideas) aren't valued, it's because
+I'm a bit overloaded with information at the moment. Please let me know
+immediately and I will correct my oversight.
+
+Thanks everyone for helping make random_compat better.
+
+### Version 1.0.5 - 2015-10-08
+
+Got rid of the methods in the `Throwable` interface, which was causing problems
+on PHP 5.2. While we would normally not care about 5.2 (since [5.4 and earlier are EOL'd](https://secure.php.net/supported-versions.php)),
+we do want to encourage widespread adoption (e.g. [Wordpress](https://core.trac.wordpress.org/ticket/28633)).
+
+### Version 1.0.4 - 2015-10-02
+
+Removed redundant `if()` checks, since `lib/random.php` is the entrypoint people
+should use.
+
+### Version 1.0.3 - 2015-10-02
+
+This release contains bug fixes contributed by the community.
+
+* Avoid a PHP Notice when PHP is running without the mbstring extension
+* Use a compatible version of PHPUnit for testing on older versions of PHP
+
+Although none of these bugs were outright security-affecting, updating ASAP is
+still strongly encouraged.
+
+### Version 1.0.2 - 2015-09-23
+
+Less strict input validation on `random_int()` parameters. PHP 7's `random_int()`
+accepts strings and floats that look like numbers, so we should too.
+
+Thanks [@dd32](https://github.com/@dd32) for correcting this oversight.
+
+### Version 1.0.1 - 2015-09-10
+
+Instead of throwing an Exception immediately on insecure platforms, only do so
+when `random_bytes()` is invoked.
+
+### Version 1.0.0 - 2015-09-07
+
+Our API is now stable and forward-compatible with the CSPRNG features in PHP 7
+(as of 7.0.0 RC3).
+
+A lot of great people have contributed their time and expertise to make this
+compatibility library possible. That this library has reached a stable release
+is more a reflection on the community than it is on PIE.
+
+We are confident that random_compat will serve as the simplest and most secure
+CSPRNG interface available for PHP5 projects.
+
+### Version 0.9.7 (pre-release) - 2015-09-01
+
+An attempt to achieve compatibility with Error/TypeError in the RFC.
+
+This should be identical to 1.0.0 sans any last-minute changes or performance enhancements.
+
+### Version 0.9.6 (pre-release) - 2015-08-06
+
+* Split the implementations into their own file (for ease of auditing)
+* Corrected the file type check after `/dev/urandom` has been opened (thanks
+ [@narfbg](https://github.com/narfbg) and [@jedisct1](https://github.com/jedisct1))
+
+### Version 0.9.5 (pre-release) - 2015-07-31
+
+* Validate that `/dev/urandom` is a character device
+ * Reported by [@lokdnet](https://twitter.com/lokdnet)
+ * Investigated by [@narfbg](https://github.com/narfbg) and [frymaster](http://stackoverflow.com/users/1226810/frymaster) on [StackOverflow](http://stackoverflow.com/q/31631066/2224584)
+* Remove support for `/dev/arandom` which is an old OpenBSD feature, thanks [@jedisct1](https://github.com/jedisct1)
+* Prevent race conditions on the `filetype()` check, thanks [@jedisct1](https://github.com/jedisct1)
+* Buffer file reads to 8 bytes (performance optimization; PHP defaults to 8192 bytes)
+
+### Version 0.9.4 (pre-release) - 2015-07-27
+
+* Add logic to verify that `/dev/arandom` and `/dev/urandom` are actually devices.
+* Some clean-up in the comments
+
+### Version 0.9.3 (pre-release) - 2015-07-22
+
+Unless the Exceptions change to PHP 7 fails, this should be the last pre-release
+version. If need be, we'll make one more pre-release version with compatible
+behavior.
+
+Changes since 0.9.2:
+
+* Prioritize `/dev/arandom` and `/dev/urandom` over mcrypt.
+[@oittaa](https://github.com/oittaa) removed the -1 and +1 juggling on `$range` calculations for `random_int()`
+* Whitespace and comment clean-up, plus better variable names
+* Actually put a description in the composer.json file...
+
+### Version 0.9.2 (pre-release) - 2015-07-16
+
+* Consolidated `$range > PHP_INT_MAX` logic with `$range <= PHP_INT_MAX` (thanks
+ [@oittaa](https://github.com/oittaa) and [@CodesInChaos](https://github.com/CodesInChaos))
+* `tests/phpunit.sh` now also runs the tests with `mbstring.func_overload` and
+ `open_basedir`
+* Style consistency, whitespace cleanup, more meaningful variable names
+
+### Version 0.9.1 (pre-release) - 2015-07-09
+
+* Return random values on integer ranges > `PHP_INT_MAX` (thanks [@CodesInChaos](https://github.com/CodesInChaos))
+* Determined CSPRNG preference:
+ 1. `mcrypt_create_iv()` with `MCRYPT_DEV_URANDOM`
+ 2. `/dev/arandom`
+ 3. `/dev/urandom`
+ 4. `openssl_random_pseudo_bytes()`
+* Optimized backend selection (thanks [@lt](https://github.com/lt))
+* Fix #3 (thanks [@scottchiefbaker](https://github.com/scottchiefbaker))
+
+### Version 0.9.0 (pre-release) - 2015-07-07
+
+This should be a sane polyfill for PHP 7's `random_bytes()` and `random_int()`.
+We hesitate to call it production ready until it has received sufficient third
+party review.

+## Rationale (Design Decisions)
+
+### Reasoning Behind the Order of Preferred Random Data Sources
+
+The order is:
+
+ 1. `libsodium if available`
+ 2. `fread() /dev/urandom if available`
+ 3. `mcrypt_create_iv($bytes, MCRYPT_DEV_URANDOM)`
+ 4. `COM('CAPICOM.Utilities.1')->GetRandom()`
+
+If libsodium is available, we get random data from it. This is the preferred
+method on all OSes, but libsodium is not very widely installed, so other
+fallbacks are available.
+
+Next, we read `/dev/urandom` (if it exists). This is the preferred file to read
+for random data for cryptographic purposes for BSD and Linux. This step
+is skipped on Windows, because someone could create a `C:\dev\urandom`
+file and PHP would helpfully (but insecurely) return bytes from it.
+
+Despite [strongly urging people not to use mcrypt in their projects](https://paragonie.com/blog/2015/05/if-you-re-typing-word-mcrypt-into-your-code-you-re-doing-it-wrong)
+(because libmcrypt is abandonware and the API puts too much responsibility on the
+implementor) we prioritize `mcrypt_create_iv()` with `MCRYPT_DEV_URANDOM` above
+the remaining implementations.
+
+The reason is simple: `mcrypt_create_iv()` is part of PHP's `ext/mcrypt` code,
+and is not part `libmcrypt`. It actually does the right thing:
+
+ * On Unix-based operating systems, it reads from `/dev/urandom` which
+ (unlike `/dev/random`) is the sane and correct thing to do.
+ * On Windows, it reads from `CryptGenRandom`, which is an exclusively Windows
+ way to get random bytes.
+
+If we're on Windows and don't have access to `mcrypt`, we use `CAPICOM.Utilities.1`.
+
+As of random_compat 2.0, we no longer fall through to OpenSSL.

+
+PHP 5.x polyfill for `random_bytes()` and `random_int()` created and maintained
+by [Paragon Initiative Enterprises](https://paragonie.com).
+
+Although this library *should* function in earlier versions of PHP, we will only
+consider issues relevant to [supported PHP versions](https://secure.php.net/supported-versions.php).
+**If you are using an unsupported version of PHP, please upgrade as soon as possible.**
+
+## Important
+
+Although this library has been examined by some security experts in the PHP
+community, there will always be a chance that we overlooked something. Please
+ask your favorite trusted hackers to hammer it for implementation errors and
+bugs before even thinking about deploying it in production.
+
+**Do not use the master branch, use a [stable release](https://github.com/paragonie/random_compat/releases/latest).**
+
+For the background of this library, please refer to our blog post on
+[Generating Random Integers and Strings in PHP](https://paragonie.com/blog/2015/07/how-safely-generate-random-strings-and-integers-in-php).
+
+### Usability Notice
+
+If PHP cannot safely generate random data, this library will throw an `Exception`.
+It will never fall back to insecure random data. If this keeps happening, upgrade
+to a newer version of PHP immediately.
+
+## Installing
+
+**With [Composer](https://getcomposer.org):**
+
+ # For libraries and frameworks that support PHP 5 but may be used by
+ # other software that only supports PHP 7:
+ composer require paragonie/random_compat:\>=2
+
+ # For software that explicitly needs PHP 5 support:
+ composer require paragonie/random_compat:\<9.99
+
+**Signed PHP Archive:**
+
+As of version 1.2.0, we also ship an ECDSA-signed PHP Archive with each stable
+release on Github.
+
+1. Download [the `.phar`, `.phar.pubkey`, and `.phar.pubkey.asc`](https://github.com/paragonie/random_compat/releases/latest) files.
+2. (**Recommended** but not required) Verify the PGP signature of `.phar.pubkey`
+ (contained within the `.asc` file) using the [PGP public key for Paragon Initiative Enterprises](https://paragonie.com/static/gpg-public-key.txt).
+3. Extract both `.phar` and `.phar.pubkey` files to the same directory.
+4. `require_once "/path/to/random_compat.phar";`
+5. When a new version is released, you only need to replace the `.phar` file;
+ the `.pubkey` will not change (unless our signing key is ever compromised).
+
+**Manual Installation:**
+
+1. Download [a stable release](https://github.com/paragonie/random_compat/releases/latest).
+2. Extract the files into your project.
+3. `require_once "/path/to/random_compat/lib/random.php";`
+
+The entrypoint should be **`lib/random.php`** directly, not any of the other files in `/lib`.
+
+## Usage
+
+This library exposes the [CSPRNG functions added in PHP 7](https://secure.php.net/manual/en/ref.csprng.php)
+for use in PHP 5 projects. Their behavior should be identical.
+
+### Generate a string of random bytes
+
+```php
+try {
+ $string = random_bytes(32);
+} catch (TypeError $e) {
+ // Well, it's an integer, so this IS unexpected.
+ die("An unexpected error has occurred");
+} catch (Error $e) {
+ // This is also unexpected because 32 is a reasonable integer.
+ die("An unexpected error has occurred");
+} catch (Exception $e) {
+ // If you get this message, the CSPRNG failed hard.
+ die("Could not generate a random string. Is our OS secure?");
+}
+
+var_dump(bin2hex($string));
+// string(64) "5787c41ae124b3b9363b7825104f8bc8cf27c4c3036573e5f0d4a91ad2eeac6f"
+```
+
+### Generate a random integer between two given integers (inclusive)
+
+```php
+try {
+ $int = random_int(0, 255);
+} catch (TypeError $e) {
+ // Well, it's an integer, so this IS unexpected.
+ die("An unexpected error has occurred");
+} catch (Error $e) {
+ // This is also unexpected because 0 and 255 are both reasonable integers.
+ die("An unexpected error has occurred");
+} catch (Exception $e) {
+ // If you get this message, the CSPRNG failed hard.
+ die("Could not generate a random int. Is our OS secure?");
+}
+
+var_dump($int);
+// int(47)
+```
+
+### Exception handling
+
+When handling exceptions and errors you must account for differences between
+PHP 5 and PHP7.
+
+The differences:
+
+* Catching `Error` works, so long as it is caught before `Exception`.
+* Catching `Exception` has different behavior, without previously catching `Error`.
+* There is *no* portable way to catch all errors/exceptions.
+
+#### Our recommendation
+
+**Always** catch `Error` before `Exception`.
+
+#### Example
+
+```php
+try {
+ return random_int(1, $userInput);
+} catch (TypeError $e) {
+ // This is okay, so long as `Error` is caught before `Exception`.
+ throw new Exception('Please enter a number!');
+} catch (Error $e) {
+ // This is required, if you do not need to do anything just rethrow.
+ throw $e;
+} catch (Exception $e) {
+ // This is optional and maybe omitted if you do not want to handle errors
+ // during generation.
+ throw new InternalServerErrorException(
+ 'Oops, our server is bust and cannot generate any random data.',
+ 500,
+ $e
+ );
+}
+```
+
+### Troubleshooting
+
+#### Exception: "Could not gather sufficient random data"
+
+If an Exception is thrown, then your operating system is not secure.
+
+1. If you're on Windows, make sure you enable mcrypt.
+2. If you're on any other OS, make sure `/dev/urandom` is readable.
+ * FreeBSD jails need to expose `/dev/urandom` from the host OS
+ * If you use `open_basedir`, make sure `/dev/urandom` is allowed
+
+This library does not (and will not accept any patches to) fall back to
+an insecure random number generator.
+
+#### Version Conflict with [Other PHP Project]
+
+If you're using a project that has a line like this in its composer.json
+
+ "require" {
+ ...
+ "paragonie/random_compat": "~1.1",
+ ...
+ }
+
+...and then you try to add random_compat 2 (or another library that explicitly
+requires random_compat 2, such as [this secure PHP encryption library](https://github.com/defuse/php-encryption)),
+you will get a version conflict.
+
+The solution is to get the project to update its requirement string to allow
+version 2 and above to be used instead of hard-locking users to version 1.
+
+```diff
+"require" {
+ ...
+- "paragonie/random_compat": "~1.1",
++ "paragonie/random_compat": ">=1",
+ ...
+}
+```
+
+#### Version 9.99.99
+
+**Note**: There is a special version called `9.99.99` which makes this
+library do nothing, but is only installable on PHP 7.
+
+If you're writing software (e.g. a library) that supports PHP 5, but may
+be used by software that doesn't, you'll want to allow `9.99.99` to be
+installed. The above diff is what you want.
+
+Conversely, if you're writing software that (in and of itself) supports
+PHP 5, you do not want 9.99.99 to be installed, so you'll want to make
+this change instead:
+
+```diff
+"require" {
+ ...
+- "paragonie/random_compat": "~1.1",
++ "paragonie/random_compat": ">=1 <9.99",
+ ...
+}
+```
+
+To avoid installing "empty" version `9.99.99` you can add `replace` section
+in your root `composer.json`:
+
+ "replace": {
+ "paragonie/random_compat": "9.99.99"
+ },
+
+#### Manifest Read Length Error
+
+If you're using the PHP Archive (Phar) approach rather than Composer, and
+you are getting an error message to the effect of "manifest read length
+was `{int1}` should be `{int2}`", the Phar extension may not be enabled.
+
+See [this comment](https://github.com/paragonie/random_compat/issues/134#issuecomment-365696289)
+for specific guidance on how to fix this issue.

+with a diverse community. We understand and appreciate the importance of Full
+Disclosure in the history and practice of security research.
+
+We would *like* to know about high-severity bugs before they become public
+knowledge, so we can fix them in a timely manner, but **we do not believe in
+threatening researchers or trying to enforce vulnerability embargoes**.
+
+Ultimately, if you discover a security-affecting vulnerability, what you do with
+it is your choice. We would like to work with people, and to celebrate and
+reward their skill, experience, and dedication. We appreciate being informed of
+our mistakes so we can learn from them and build a better product. Our goal is
+to empower the community.
+
+### Where to Send Security Vulnerabilities
+
+Our security email address is `security@paragonie.com`. Also feel free to open a
+new issue on Github if you want to disclose publicly.

+
+### We Will Reward Security Researchers
+
+**This process has not been formalized; nor have dollar amounts been
+discussed.**
+
+However, if you report a valid security-affecting bug, we will compensate you
+for the time spent finding the vulnerability and reward you for being a good
+neighbor.
+
+#### What does a "valid" bug mean?
+
+There are two sides to this:
+
+1. Some have spammed projects with invalid bug reports hoping to collect
+ bounties for pressing a button and running an automated analysis tool. This
+ is not cool.
+2. There is a potential for the developers of a project to declare all security
+ bug reports as invalid to save money.
+
+Our team members have an established history of reporting vulnerabilities to
+large open source projects. **We aren't in the business of ripping people off.**
+When in doubt, our policy is to err on the side of generosity.
+
+### No Proof-of-Concept Required
+
+We might ask for one if we feel we do not understand some of the details
+pertaining to a specific vulnerability. We certainly appreciate them if you
+include them in your report, but we believe **the burden lies with the developer
+to prove their software *is* secure** rather than with the researcher to prove
+that it isn't.
+
+In our experience, most bugs are simpler to fix than they are to exploit.

+# Sodium Compat
+
+[](https://travis-ci.org/paragonie/sodium_compat)
+[](https://ci.appveyor.com/project/paragonie-scott/sodium-compat)
+[](https://packagist.org/packages/paragonie/sodium_compat)
+[](https://packagist.org/packages/paragonie/sodium_compat)
+[](https://packagist.org/packages/paragonie/sodium_compat)
+[](https://packagist.org/packages/paragonie/sodium_compat)
+
+Sodium Compat is a pure PHP polyfill for the Sodium cryptography library
+(libsodium), a core extension in PHP 7.2.0+ and otherwise [available in PECL](https://pecl.php.net/package/libsodium).
+
+This library tentativeley supports PHP 5.2.4 - 7.x (latest), but officially
+only supports [non-EOL'd versions of PHP](https://secure.php.net/supported-versions.php).
+
+If you have the PHP extension installed, Sodium Compat will opportunistically
+and transparently use the PHP extension instead of our implementation.
+
+## IMPORTANT!
+
+This cryptography library has not been formally audited by an independent third
+party that specializes in cryptography or cryptanalysis.
+
+If you require such an audit before you can use sodium_compat in your projects
+and have the funds for such an audit, please open an issue or contact
+`security at paragonie dot com` so we can help get the ball rolling.
+
+However, sodium_compat has been adopted by high profile open source projects,
+such as [Joomla!](https://github.com/joomla/joomla-cms/blob/459d74686d2a638ec51149d7c44ddab8075852be/composer.json#L40)
+and [Magento](https://github.com/magento/magento2/blob/8fd89cfdf52c561ac0ca7bc20fd38ef688e201b0/composer.json#L44).
+Furthermore, sodium_compat was developed by Paragon Initiative Enterprises, a
+company that *specializes* in secure PHP development and PHP cryptography, and
+has been informally reviewed by many other security experts who also specialize
+in PHP.
+
+If you'd like to learn more about the defensive security measures we've taken
+to prevent sodium_compat from being a source of vulnerability in your systems,
+please read [*Cryptographically Secure PHP Development*](https://paragonie.com/blog/2017/02/cryptographically-secure-php-development).
+
+# Installing Sodium Compat
+
+If you're using Composer:
+
+```bash
+composer require paragonie/sodium_compat
+```
+
+### Install From Source
+
+If you're not using Composer, download a [release tarball](https://github.com/paragonie/sodium_compat/releases)
+(which should be signed with [our GnuPG public key](https://paragonie.com/static/gpg-public-key.txt)), extract
+its contents, then include our `autoload.php` script in your project.
+
+```php
+<?php
+require_once "/path/to/sodium_compat/autoload.php";
+```
+
+### PHP Archives (Phar) Releases
+
+Since version 1.3.0, [sodium_compat releases](https://github.com/paragonie/sodium_compat/releases) include a
+PHP Archive (.phar file) and associated GPG signature. First, download both files and verify them with our
+GPG public key, like so:
+
+```bash
+# Getting our public key from the keyserver:
+gpg --fingerprint 7F52D5C61D1255C731362E826B97A1C2826404DA
+if [ $? -ne 0 ]; then
+ echo -e "\033[33mDownloading PGP Public Key...\033[0m"
+ gpg --keyserver pgp.mit.edu --recv-keys 7F52D5C61D1255C731362E826B97A1C2826404DA
+ # Security <security@paragonie.com>
+ gpg --fingerprint 7F52D5C61D1255C731362E826B97A1C2826404DA
+ if [ $? -ne 0 ]; then
+ echo -e "\033[31mCould not download PGP public key for verification\033[0m"
+ exit 1
+ fi
+fi
+
+# Verifying the PHP Archive
+gpg --verify sodium-compat.phar.sig sodium-compat.phar
+```
+
+Now, simply include this .phar file in your application.
+
+```php
+<?php
+require_once "/path/to/sodium-compat.phar";
+```
+
+# Support
+
+[Commercial support for libsodium](https://download.libsodium.org/doc/commercial_support/) is available
+from multiple vendors. If you need help using sodium_compat in one of your projects, [contact Paragon Initiative Enterprises](https://paragonie.com/contact).
+
+Non-commercial report will be facilitated through [Github issues](https://github.com/paragonie/sodium_compat/issues).
+We offer no guarantees of our availability to resolve questions about integrating sodium_compat into third-party
+software for free, but will strive to fix any bugs (security-related or otherwise) in our library.
+
+## Support Contracts
+
+If your company uses this library in their products or services, you may be
+interested in [purchasing a support contract from Paragon Initiative Enterprises](https://paragonie.com/enterprise).
+
+# Using Sodium Compat
+
+## True Polyfill
+
+If you're using PHP 5.3.0 or newer and do not have the PECL extension installed,
+you can just use the [standard ext/sodium API features as-is](https://paragonie.com/book/pecl-libsodium)
+and the polyfill will work its magic.
+
+```php
+<?php
+require_once "/path/to/sodium_compat/autoload.php";
+
+$alice_kp = \Sodium\crypto_sign_keypair();
+$alice_sk = \Sodium\crypto_sign_secretkey($alice_kp);
+$alice_pk = \Sodium\crypto_sign_publickey($alice_kp);
+
+$message = 'This is a test message.';
+$signature = \Sodium\crypto_sign_detached($message, $alice_sk);
+if (\Sodium\crypto_sign_verify_detached($signature, $message, $alice_pk)) {
+ echo 'OK', PHP_EOL;
+} else {
+ throw new Exception('Invalid signature');
+}
+```
+
+The polyfill does not expose this API on PHP < 5.3, or if you have the PHP
+extension installed already.
+
+## General-Use Polyfill
+
+If your users are on PHP < 5.3, or you want to write code that will work
+whether or not the PECL extension is available, you'll want to use the
+**`ParagonIE_Sodium_Compat`** class for most of your libsodium needs.
+
+The above example, written for general use:
+
+```php
+<?php
+require_once "/path/to/sodium_compat/autoload.php";
+
+$alice_kp = ParagonIE_Sodium_Compat::crypto_sign_keypair();
+$alice_sk = ParagonIE_Sodium_Compat::crypto_sign_secretkey($alice_kp);
+$alice_pk = ParagonIE_Sodium_Compat::crypto_sign_publickey($alice_kp);
+
+$message = 'This is a test message.';
+$signature = ParagonIE_Sodium_Compat::crypto_sign_detached($message, $alice_sk);
+if (ParagonIE_Sodium_Compat::crypto_sign_verify_detached($signature, $message, $alice_pk)) {
+ echo 'OK', PHP_EOL;
+} else {
+ throw new Exception('Invalid signature');
+}
+```
+
+Generally: If you replace `\Sodium\ ` with `ParagonIE_Sodium_Compat::`, any
+code already written for the libsodium PHP extension should work with our
+polyfill without additional code changes.
+
+Since this doesn't require a namespace, this API *is* exposed on PHP 5.2.
+
+Since version 0.7.0, we have our own namespaced API (`ParagonIE\Sodium\*`) to allow brevity
+in software that uses PHP 5.3+. This is useful if you want to use our file cryptography
+features without writing `ParagonIE_Sodium_File` every time. This is not exposed on PHP < 5.3,
+so if your project supports PHP < 5.3, use the underscore method instead.
+
+To learn how to use Libsodium, read [*Using Libsodium in PHP Projects*](https://paragonie.com/book/pecl-libsodium).
+
+## PHP 7.2 Polyfill
+
+As per the [second vote on the libsodium RFC](https://wiki.php.net/rfc/libsodium#proposed_voting_choices),
+PHP 7.2 uses `sodium_*` instead of `\Sodium\*`.
+
+```php
+<?php
+require_once "/path/to/sodium_compat/autoload.php";
+
+$alice_kp = sodium_crypto_sign_keypair();
+$alice_sk = sodium_crypto_sign_secretkey($alice_kp);
+$alice_pk = sodium_crypto_sign_publickey($alice_kp);
+
+$message = 'This is a test message.';
+$signature = sodium_crypto_sign_detached($message, $alice_sk);
+if (sodium_crypto_sign_verify_detached($signature, $message, $alice_pk)) {
+ echo 'OK', PHP_EOL;
+} else {
+ throw new Exception('Invalid signature');
+}
+```
+
+## Help, Sodium_Compat is Slow! How can I make it fast?
+
+There are three ways to make it fast:
+
+1. Use PHP 7.2.
+2. [Install the libsodium PHP extension from PECL](https://paragonie.com/book/pecl-libsodium/read/00-intro.md#installing-libsodium).
+3. Only if the previous two options are not available for you:
+ 1. Verify that [the processor you're using actually implements constant-time multiplication](https://bearssl.org/ctmul.html).
+ Sodium_compat does, but it must trade some speed in order to attain cross-platform security.
+ 2. Only if you are 100% certain that your processor is safe, you can set `ParagonIE_Sodium_Compat::$fastMult = true;`
+ without harming the security of your cryptography keys. If your processor *isn't* safe, then decide whether you
+ want speed or security because you can't have both.
+
+### How can I tell if sodium_compat will be slow, at runtime?
+
+Since version 1.8, you can use the `polyfill_is_fast()` static method to
+determine if sodium_compat will be slow at runtime.
+
+```php
+<?php
+if (ParagonIE_Sodium_Compat::polyfill_is_fast()) {
+ // Use libsodium now
+ $process->execute();
+} else {
+ // Defer to a cron job or other sort of asynchronous process
+ $process->enqueue();
+}
+```
+
+### Help, my PHP only has 32-Bit Integers! It's super slow!
+
+Some features of sodium_compat are ***incredibly slow* with PHP 5 on Windows**
+(in particular: public-key cryptography (encryption and signatures) is
+affected), and there is nothing we can do about that, due to platform
+restrictions on integers.
+
+For acceptable performance, we highly recommend Windows users to version 1.0.6
+of the libsodium extension from PECL or, alternatively, simply upgrade to PHP 7
+and the slowdown will be greatly reduced.
+
+This is also true of non-Windows 32-bit operating systems, or if somehow PHP
+was compiled where `PHP_INT_SIZE` equals `4` instead of `8` (i.e. Linux on i386).
+
+## Documentation
+
+First, you'll want to read the [Libsodium Quick Reference](https://paragonie.com/blog/2017/06/libsodium-quick-reference-quick-comparison-similar-functions-and-which-one-use).
+It aims to answer, "Which function should I use for [common problem]?".
+
+If you don't find the answers in the Quick Reference page, check out
+[*Using Libsodium in PHP Projects*](https://paragonie.com/book/pecl-libsodium).
+
+Finally, the [official libsodium documentation](https://download.libsodium.org/doc/)
+(which was written for the C library, not the PHP library) also contains a lot of
+insightful technical information you may find helpful.
+

+### Cryptography Primitives Provided
+
+* **X25519** - Elliptic Curve Diffie Hellman over Curve25519
+* **Ed25519** - Edwards curve Digital Signature Algorithm over Curve25519
+* **Xsalsa20** - Extended-nonce Salsa20 stream cipher
+* **ChaCha20** - Stream cipher
+* **Xchacha20** - Extended-nonce ChaCha20 stream cipher
+* **Poly1305** - Polynomial Evaluation Message Authentication Code modulo 2^130 - 5
+* **BLAKE2b** - Cryptographic Hash Function
+* **SipHash-2-4** - Fast hash, but not collision-resistant; ideal for hash tables.
+
+### Features Excluded from this Polyfill
+
+* `\Sodium\memzero()` - Although we expose this API endpoint, we can't reliably
+ zero buffers from PHP.
+
+ If you have the PHP extension installed, sodium_compat
+ will use the native implementation to zero out the string provided. Otherwise
+ it will throw a `SodiumException`.
+* `\Sodium\crypto_pwhash()` - It's not feasible to polyfill scrypt or Argon2
+ into PHP and get reasonable performance. Users would feel motivated to select
+ parameters that downgrade security to avoid denial of service (DoS) attacks.
+
+ The only winning move is not to play.
+
+ If ext/sodium or ext/libsodium is installed, these API methods will fallthrough
+ to the extension. Otherwise, our polyfill library will throw a `SodiumException`.
+
+ To detect support for Argon2i at runtime, use
+ `ParagonIE_Sodium_Compat::crypto_pwhash_is_available()`, which returns a
+ boolean value (`TRUE` or `FALSE`).
+
+### PHPCompatibility Ruleset
+
+For sodium_compat users and that utilize [`PHPCompatibility`](https://github.com/PHPCompatibility/PHPCompatibility)
+in their CI process, there is now a custom ruleset available which can be used
+to prevent false positives being thrown by `PHPCompatibility` for the native
+PHP functionality being polyfilled by this repo.
+
+You can find the repo for the `PHPCompatibilityParagonieSodiumCompat` ruleset
+here [on Github](https://github.com/PHPCompatibility/PHPCompatibilityParagonie)
+and [on Packagist](https://packagist.org/packages/phpcompatibility/phpcompatibility-paragonie).
