As far as I can tell, the real-world MTI for SSL/TLS as deployed is RC4. I dislike it when the real world MTI and the specified MTI differ and the specification fails to explain the difference. It's my belief that AES-CBC is more likely to result in future alignment of the real-world MTI and the specified MTI than 3DES and thus I support a change from 3DES to AES as MTI. I would also support a change from 3DES to RC4 as MTI despite some concerns about the cryptographic longevity of that cipher. - Chris Eric Rescorla wrote on 9/12/07 16:26 -0700: > At Wed, 12 Sep 2007 19:27:17 -0400, > Yee, Peter wrote: >> >> Just AES in general or a specific key size and mode?
