Interscope BlackBox is a Windows shell enhancement that allows you to encrypt or decrypt files with only two quick clicks of the mouse.

With BlackBox, simply right-click on any encrypted file, select Encrypt or Decrypt, and type a password. BlackBox uses the very secure DES (Data Encryption Standard). Besides the standard 56-bit key version of DES, BlackBox also offers a speedier implementation that doesn't perform the initial and final key permutations.

In addition to DES encryption, you can download additional encryption engine plug-ins from the author's site, including Blowfish, RC4, and IDEA. A software development kit is also available from the author's site.
