9 2) The only way to get a significant speedup of the algorithm is to
10 use considerably more space, traded against time. Dont play
11 with the code -- there is a high probability you will either
12 make it slower, or wrong, or both. This implementation was
13 optimized for the UVAX 2. Other architectures could benefit from
16 3) If you do play with the code, make sure that the test program
17 "verify" still yields the expected answers. Otherwise, your
18 ciphertext will not decrypt under a standard implementation, such
19 as on the VLSI chips that have been certified.
