- This directory contains the sources for the DES encryption library and
- test programs.

- Two precautions--
-
- 1) under US law, DES software and hardware may not be
- exported without license from the US Dept of Commerce.
-
- 2) The only way to get a significant speedup of the algorithm is to
- use considerably more space, traded against time. Dont play
- with the code -- there is a high probability you will either
- make it slower, or wrong, or both. This implementation was
- optimized for the UVAX 2. Other architectures could benefit from
- some "asm" tweaking.
-
- 3) If you do play with the code, make sure that the test program
- "verify" still yields the expected answers. Otherwise, your
- ciphertext will not decrypt under a standard implementation, such
- as on the VLSI chips that have been certified.
