I believe it -conforms to the sun version. - -The Imakefile is setup for use in the kerberos distribution. - -These routines are best compiled with gcc or any other good -optimising compiler. -Just turn you optimiser up to the highest settings and run destest -after the build to make sure everything works. - -I believe these routines are close to the fastest and most portable DES -routines that use small lookup tables (4.5k) that are publicly available. -The fcrypt routine is faster than ufc's fcrypt (when compiling with -gcc2 -O2) on the sparc 2 (1410 vs 1270) but is not so good on other machines -(on a sun3/260 168 vs 336). It is a function of CPU on chip cache size. -[ 10-Jan-97 and a function of an incorrect speed testing program in - ufc which gave much better test figures that reality ]. - -It is worth noting that on sparc and Alpha CPUs, performance of the DES -library can vary by upto %10 due to the positioning of files after application -linkage. - -Eric Young (eay@cryptsoft.com) - |
