If this issue seems to be a problem for a particular cypher, there are a couple of ways to try to solve it: * Compress out the eighth bit (requiring 10 characters for a 64 bit block cypher instead of 8). * Remember a pattern of high order bits. Something like 11110000 would be relatively easy to remember, and would help mitigate signed vs. unsigned number problems on 32 bit machines.
