I'm interested in a 256 bits (or more) message digest algorithm (C source is better). Any URLs ? Try HAVAL. It is a variable one-way hash function that is apparently secure against collisions. It should be on any of the standard crypto FTP sites.

Or there's the simple "MD5(x),SHA(x)", which is 288 bits long and has the advantage that the two parts have different characteristics and have been looked at (separately) by many people, so concatenating them should be fairly strong. Or "MD5(SHA(x)),SHA(MD5(x))" if you're paranoid. # Thanks; Bill # Bill Stewart, +1-415-442-2215 stewarts@ix.netcom.com # <A HREF="http://idiom.com/~wcs"> # You can get PGP software outside the US at ftp.ox.ac.uk/pub/crypto
