Hi,
To be able to decode SigComp messages not containing byte code  a SHA-1 signature is needed:
RFC3320:
" The UDVM then calculates a 20-byte SHA-1 hash [RFC-3174] over the
byte string formed by concatenating the state_length, state_address,
state_instruction, minimum_access_length and state_value (in the
order given). This is the state_identifier."
Currently we do not have a SHA-1 function in Ethereal, is any one interested in helping out to provide one ? For SigComp I'd like
to pas the function a buff[] and get the 20byte digest back, perhaps we'd also like to pas it a tvb ?
Possible candidates to use or build on:

Ideas or comments welcome.
Best regards
