This library is a reference implementation of PASETO in the PHP language. Please refer to the [**PASETO Specification**](https://github.com/paseto-standard/paseto-spec)for design considerations. How to Use this Library ----------------------- [](#how-to-use-this-library) See [the documentation](https://github.com/paragonie/paseto/tree/master/docs). The [PASETO specification](https://github.com/paseto-standard/paseto-spec) may also be useful for understanding why things are designed the way they are. ### PASETO Extensions [](#paseto-extensions) #### PASERK [](#paserk) For key wrapping, serialization, and canonical identification, please see the [PHP implementation of PASERK](https://github.com/paragonie/paserk-php). If you're not sure what that means, please refer to the [PASERK specification](https://github.com/paseto-standard/paserk). Since PASERK is a PASETO extension, PASERK support is not automatically included with PASETO, but PASETO is bundled with PASERK. ### Requirements [](#requirements) #### PHP PASETO Library Version 3 [](#php-paseto-library-version-3) - Requires PHP 8.1 or newer. - For v3 tokens, the GMP and OpenSSL extensions are required. - For v4 tokens, the Sodium extension is strongly recommended (but this library will use [sodium\_compat](https://github.com/paragonie/sodium_compat) if it's not). - PASETO Protocol versions: `v3`, `v4` #### PHP PASETO Library Version 2 [](#php-paseto-library-version-2) - Requires PHP 7.1 or newer. - For v3 tokens, the GMP and OpenSSL extensions are required. - For v4 tokens, the Sodium extension is strongly recommended (but this library will use [sodium\_compat](https://github.com/paragonie/sodium_compat) if it's not). - PASETO Protocol versions: `v1`, `v2`, `v3`, `v4` #### PHP PASETO Library Version 1 [](#php-paseto-library-version-1) - Requires PHP 7.0 or newer. - For v1 tokens, the OpenSSL extension is required. - For v2 tokens, the Sodium extension is strongly recommended (but this library will use [sodium\_compat](https://github.com/paragonie/sodium_compat) if it's not). - PASETO Protocol versions: `v1`, `v2` Support Contracts ----------------- [](#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). ### Health Score 28 — LowBetter than 54% of packages Maintenance34 Infrequent updates — may be unmaintained Popularity6 Limited adoption so far Community19 Small or concentrated contributor base Maturity49 Maturing project, gaining track record Bus Factor1 Top contributor holds 71.8% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
