You could take advantage of Perl's Bitwise String Operators to XOR your data against a shared key. This is completely useless against any hacker with half a clue, but is a popular method for obfuscation where true security is not critical. It's marginally more secure than ROT-N, and arguably simpler to implement -- I suspect it may be more efficient too, though I haven't bothered to benchmark anything.
