That part's easy - DES source is available on ftp.ox.ac.uk, and also on ftp.dsi.unimi.it and ftp.funet.fi. There may be specific triple-DES code there, but if not, triple DES is just Encrypt(Key1, Decrypt(Key2, Encrypt(Key3, Message))) so you can easily write a subroutine to do that.
I got carried away with adding triple DES to libdes v 3.21+ (listed at most of the above mentioned sites) back in november. It has routines for triple DES in ecb, cbc, cfb64 and ofb64 modes. The SSLeay package builds a utility called 'enc' which can encrypt/decrypt with optional base64 conversion in any of the above mentioned modes (plus more). Infact, SSLeay has much nicer higher level 'by parts' finctions for the ciphers that are much easier to use. eric -- Eric Young | Signature removed since it was generating AARNet: eay@mincom.oz.au | more followups than the message contents :-)
