koontz-des.tar.Z David G. Koontz <2004ktz%ucsbuxa@hub.ucsb.edu> Fast but large DES C functions and main program. Dates to March 1991, at which time it was one of the fastest around. Good verification suite included.

I have three or four faster versions, when I think about it I try and produce smaller code (Cache size limits, don't you know)
