About
-----

[](#about)

This package allow to convert common cryptographic structures from binary ASN.1 format to PHP Objects.

- CMS (according to [RFC3852](https://datatracker.ietf.org/doc/html/rfc3852))
- CAdES (according to [RFC5126](https://datatracker.ietf.org/doc/html/rfc5126))
- x.509 Certificates, CRLs (according to [RFC 5280](https://datatracker.ietf.org/doc/html/rfc5280))
- etc.

This is a pure PHP library and does not require any cryptographic extensions (like ext-openssl) to be installed.

You can find examples, how to use this library [here](example)

How to extend
-------------

[](#how-to-extend)

You can create your own Map (see examples under `Adapik\CMS\Maps` namespace) and Object (see examples under `Adapik\CMS`namespace) and decode any ASN.1 structure.

What this package is not
------------------------

[](#what-this-package-is-not)

It's not a tool to create or validate CMS or CAdES, but you can build your own tool, using objects from this library.
