did not know much about cryptography back then, beyond what I learned
in a Helman seminar. The algorithm was intended to address what was a
concern at the time for DES - the transparency of the design. People
were concerned about the possibility of trap-doors known only to the
designers. For that reason I chose to develop a random S-box based on
the text of the Declaration of Independence, as described in the
original Cryptologia article. A carefully crafted S-box may have
produced a stronger algorithm, but it would not have passed the test
of transparent design.
I must admit that NEWDES is not very good, especially in light of all
