A PHP library for X.509 public key certificates, attribute certificates,

certification requests and certification path validation.

## 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

- 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

- PHP >=7.2

- 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)
