There's something wrong with:
@k = unpack( 'C*', pack( 'H*', shift ) );
I tried with key "ciao" and
@k ends up with only two elements instead of 4 as in the C version, which operates on all 4 characters. I really don't know anything about pack/unpack, so I cannot solve the problem without studying it, and it's friday afternoon :)
Update: sorry, fried in friday, I completely missed the pre-calculations over the input key, ikegami answer forced me to take a deeper look. I swear I'll re-read it, in the meantime "--" me!
Flavio (perl -e 'print(scalar(reverse("\nti.xittelop\@oivalf")))')
Don't fool yourself.
