Parallel md5 & sha1 hashing...

Subject: Parallel md5 & sha1 hashing...
Date: Tue, 14 Sep 2004 15:04:56 -0400
Everyone,

http://www.crossrealm.com/2hash
I created this a few months ago, but with the recent md5 collision
issues, thought I'd go ahead an release it. It's a tool that does md5
and sha1 hashing in parallel. It runs with only about an 8% increase in
time over md5 alone, and only about a 2% increase over sha1 alone. It is
definitely much faster (90-95%) than running a md5 hash and then a sha1
hash serially... I've published the source, and windows and linux
binaries at http://www.crossrealm.com/2hash. Let me know what you think
or if you have any suggestions for improvement...

Thanks!
