DES binaries for Mac -

I'm looking for DES encryption software for a Mac that can read cbc-encrypted data created with the "des" command on a UNIX box. I found one version of DES for Macs (powers-MacDES.sit.hqx) that appears to do DES properly but uses the resource fork in some way such that it won't try to decrypt files it didn't create. Anyone out there a Mac wizard who can point me at a compatible binary? I've no access to a compiler, and I'm under too tight a schedule to port something myself. Please, buddy, can you spare some crypto? mjr.
