The - * permutations and shifts have been done at compile time, resulting - * in a direct one-step mapping from the input key to the key - * schedule. - * - * Also checks parity and weak keys. - * - * Watch out for the subscripts -- most effectively start at 1 instead - * of at zero. Maybe some bugs in that area. - * - * DON'T change the data types for arrays and such, or it will either - * break or run slower. This was optimized for Uvax2. - * - * In case the user wants to cache the computed key schedule, it is - * passed as an arg. Also implies that caller has explicit control - * over zeroing both the key schedule and the key. - * - * All registers labeled imply Vax using the Ultrix or 4.2bsd compiler. - * - * Originally written 6/85 by Steve Miller, MIT Project Athena. */ |
