Transliteration is what you're trying to do- map one set of characters onto another set. Specifically, you're trying to implement rot6, a transliteration cipher (not much of an encryption, btw).

tr///, aka y///, uses the second set of characters to replace their counterparts from the first set.

my $word = "abc";
$abc =~ tr/acb/llo/;
print $word;
