Hi All,
  I'm not sure this is really the right mail list for this question.  But I see SHA2 being added to many security protocols (IPsec, TLS, etc) and discussion of other algorithms fading such as MD5.

I know SRTP supports AES-CM (128, 192, 256), AES-f8, and there is a draft for AES-CCM and AES-GCM (128 and 256).

Has anyone considered or is looking at using/adding SHA2 to the SRTP protocol?     Just curious.

I know the digest size is larger but it could still be truncated.

Thanks,
Christine
