TLS uses an XOR of an MD5 over the first 128 bits, and then an
unmodified remaining 32 bits for SHA-1.
However, please note that a successful attack against TLS would
require the ability to generate a plaintext that would make both the
MD5 and the SHA1 come out to the same value.

Out of pure curiosity -
I have recently been told that all existing/used protocols had been
designed without taking into account the eventual need to adapt to new
hash lengths. How true is that ? It seems to be a topic of concern for
some people since all commonly used hashes have been broken
