PuzzlePalace is a drag and drop way to use the strong encryption tools built-in to MacOS X. By providing a graphic user interface to the system's standard openssl tools, PuzzlePalace allows all Mac OS X users to easily drag and drop encrypted files to and from Mail messages (using Mail.app) or the Desktop. PuzzlePalace also provides strong file encryption to other applications through an encryption/decryption service. Files encrypted by PuzzlePalace can by decrypted (with the pass phrase) on any platform where the OpenSSL Toolkit, and more specifically the Blowfish CBC, Triple DES CBC, IDEA CBC, CAST128 CBC and/or RC5 CBC ciphers are available. Files that are encrypted on other platforms using these standard ciphers can be decrypted by PuzzlePlace if the pass phrase is known.
