The DESTester sample uses wires, triggers, and pipes to perform a simple processing task: encrypting or decrypting a block of data using DES. The DES engine used is available from OpenCores.org.

Usage: DESTester [d|e] key infile outfile
   [d|e]   - d to decrypt the input file.  e to encrypt it.
   key     - 64-bit hexadecimal string used for the key.
   infile  - an input file to encrypt/decrypt.
   outfile - destination output file.
