Introduction ------------ [](#introduction) This library provides a pure PHP implementation of X.509 certificates. The class hierarchy adapts to the ASN.1 types, which makes it easy to use corresponding RFC's as a reference documentation. Features -------- [](#features) - X.509 certificates ([RFC 5280](https://tools.ietf.org/html/rfc5280)) - Certificate decoding and encoding - Certificate signing - Certification requests ([PKCS #10](https://tools.ietf.org/html/rfc2986)) - CSR decoding and encoding - Certification path - Path building - Path validation - Attribute certificates ([RFC 5755](https://tools.ietf.org/html/rfc5755)) - AC decoding and encoding - AC signing Requirements ------------ [](#requirements) - PHP >=7.0 - gmp - [sop/asn1](https://github.com/sop/asn1) - [sop/x501](https://github.com/sop/x501) - [sop/crypto-types](https://github.com/sop/crypto-types) - [sop/crypto-bridge](https://github.com/sop/crypto-bridge) - [sop/crypto-encoding](https://github.com/sop/crypto-encoding) Installation ------------ [](#installation) This library is available on [Packagist](https://packagist.org/packages/et-nik/x509). ``` composer require knik/x509 ``` Code examples ------------- [](#code-examples) Examples are located in [`/examples`](https://github.com/et-nik/x509/tree/master/examples)directory. - [Create a CA certificate](https://github.com/et-nik/x509/blob/master/examples/create-ca-cert.php) - [Create a CSR](https://github.com/et-nik/x509/blob/master/examples/create-csr.php) - [Issue a certificate](https://github.com/et-nik/x509/blob/master/examples/issue-cert.php) - [Validate a certification path](https://github.com/et-nik/x509/blob/master/examples/path-validate.php) License ------- [](#license) This project is licensed under the MIT License. ### Health Score 29 — LowBetter than 60% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity20 Limited adoption so far Community8 Small or concentrated contributor base Maturity55 Maturing project, gaining track record Bus Factor1 Top contributor holds 97.5% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
