-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
