There are blowfish assembler generation scripts.

bf-586.pl version is for the pentium and

bf-686.pl is my original version, which is faster on the pentium pro.

When using a bf-586.pl, the pentium pro/II is %8 slower than using

bf-686.pl. When using a bf-686.pl, the pentium is %16 slower

than bf-586.pl

So the default is bf-586.pl
