SRTP Code question

Hello,

I am new to Asterisk, and I have a question about the files associated with the Asterisk server-server SRTP encryption. Can someone tell me which file actually has the SRTP encryption algorithm in it. If not can someone point me in the right direction to someone or some site that does? I am trying to implement my own encryption algorithm and am wondering where in Asterisk would I be able to make it.

Thanks

Use the developer mailing list or IRC channel. (The actual encryption algorithm will not be in the Aterisk source code, although the call to it will be.)

Thank you.
