+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.
