The web site has a graphics file that displays as a "CipherKnight" certificate; however, that file is encrypted using CipherSaber with a known key published alongside the file. Users can view the graphic (and optionally print it out for framing) by first writing their own CipherSaber implementation to decrypt the file. By writing their own implementation and performing a few other small tasks, the user becomes a CipherKnight and the decrypted certificate attests to their knighthood. So, rather than providing a ready-made tool, CipherSaber's designer hopes to help computer users understand that they're capable of making their own strong cryptography programs without having to rely on professional developers or the permission of the government.
