The security of TLS also rests on the security of
MD5 and SHA1 (used in HMAC) and these are hard-coded.

Hi,
I hope that I'm not too off topic but recently I was reading
the draft
'AES Ciphersuites for TLS' and encountered
the folloing sentence:
'The overall strength of TLS is such that
there is no gain from using a key length longer than 128 bits.
Accordingly the AES will use 128 bit keys.'
Why not? The server and client secrets are big enough and the
keylength
of the asymmetric algorithms could be
increased. So what am I missing?
Where is the bottle
neck?
Kind regards,
Armin
