1There are blowfish assembler generation scripts.
2bf-586.pl version is for the pentium and
3bf-686.pl is my original version, which is faster on the pentium pro.
4
5When using a bf-586.pl, the pentium pro/II is %8 slower than using
6bf-686.pl. When using a bf-686.pl, the pentium is %16 slower
7than bf-586.pl
8
9So the default is bf-586.pl
