I'll point out that we're nearing the end of a selection process for
SHA-3, with a winner expected to be announced some time this year. The
winner may wind up being faster than SHA-256 or even SHA-1. (For
instance, one of the five finalists, Skein, is performance-competitive
with SHA-1 according to numbers in a paper by its authors:
It sounds like wc-ng is somewhat hash-agile by virtue of the format
number and upgrade process. It sounds like Ev2 may not be very
hash-agile. If so, it's probably a bad idea to carve SHA-1 in stone, as
it is already showing weaknesses. SHA-256 is likely to have a much
longer useful lifetime, SHA-3 even more so.
In a pinch, SHA-256 implementations can be pretty small; the one I have
on hand is about 200 lines of code.
