Fully portable command line file encryption.

Note: this tool has nothing to do with the Linux bcrypt utility.

It's a completely independent development, written during my time at the internet banking company Brokat Infosystems in 1999.

The goal was to provide a fully portable command line tool that does secure single file en/decryption on every operating system with good security. Open bcrypt uses RC4 and, most important, dynamic passphrase stretching which converts a passphrase to a long hash in as many cycles as possible within 500 milliseconds.
