Triple DES Wanted

I'm looking for a Triple DES file encryption program that takes arguments in the same form as /bin/crypt or /usr/bin/des. Is there a /bin/3des out there somewhere? Has anyone come across 3des.c? And if so, can you point me in the direction where it may be found. Thanks.. If no such program exists, I think it would be very useful to the cypherpunks community if it were made available. I'd also like to see a similar stand-alone version of IDEA (/usr/bin/idea?), but since it is patented, that's probably not going to happen, which is why I'm looking for something like /bin/3des. l8r, thug
