The only advantage over MD5 seems to be the length of the hash (160 bits
in favor of 128). Otherwise, SHA has the same advantages as MD5 over MD4,
excluding the improved bit-hashing.
"The simple Perl implementation" from the URL above is not available anymore,
unfortunately. Are there any legal concerns about a new hash algorithm in the
community? (I'm not volunteering)
