Bcrypt for AmigaOS4 encrypts and decrypts files using the blowfish algorithm. Encrypted files will be saved with an extension of .bfe. Any files ending in .bfe will be assumed to be encrypted with bcrypt and will attempt to decrypt them. Any other input files will be encrypted. If more than one type of file is given, bcrypt will process all files which are the same as the first filetype given. By default, bcrypt will compress input files before encryption, remove input files after they are processed and overwrite input files with random data to prevent data recovery. Passphrases may be between 8 and 56 characters.
