Description Aleix Conchillo Flaqué 2013-12-13 22:16:13 UTC 
Currently, srtpenc and srtpdec only support AES-128. libSRTP also support 256-bit keys so it would be great to have that available as well.

    srtp: add 256-bit key support
    
    * ext/srtp/gstsrtp.[ch]: added GST_SRTP_CIPHER_AES_256_ICM to
      GstSrtpCipherType and new function cipher_key_size.
    
    * ext/srtp/gstsrtpenc.c: maximum key size is now 46 characters (14 for
      the salt plus the key). If different ciphers are chosen for RTP and
      RTCP the maximum needed key size is expected.
    
    * ext/srtp/gstsrtpdec.c: minor documentation updates.
