Cross platform file encryption utility using blowfish - Bcrypt

Bcrypt is a cross platform file encryption utility. Encrypted files are portable across all supported operating systems and processors. Pass-phrases must be between 8 and 56 characters and are hashed internally to a 448 bit key.

In addition to encrypting your data, bcrypt will by default overwrite the original input file with random garbage three times before deleting it in order to thwart data recovery attempts by persons who may gain access to your computer.

Bcrypt uses the blowfish encryption algorithm published by Bruce Schneier in 1993. More information on the algorithm can be found at Counterpane. Specifically, bcrypt uses Paul Kocher's implementation of the algorithm.
