Hello,

We're currently developing a system that uses OAuth protocol to identify the users. The service provider is developed in PHP and uses OpenSSL to verify the access token. Unfortunately the identity provider, which is managed by another company, uses ecdsa with sha256 to sign the access tokens. Although the constants for this method (SN_ecdsa_with_SHA256 and NID_ecdsa_with_SHA256) are defined in OpenSSL, this method is currently not supported by OpenSSL.

To solve our problem I've added the required functions to OpenSSL, did few more changes, built a new shared library and gave it to our PHP developer. Now it works.

My question is, what can I do, to add my changes to the official OpenSSL sources. I'm new to github and OpenSSL development and I did not find a documentation suitable for me. We would appreciate if this method would become part of the official OpenSSL distribution.

Thanks in advance

Martin
