in reply to Personal crypting algorithm

Don't print the results. Returning them instead is a much better idea. What if the caller doesn't want the encrypted / decrypted string printed, but instead wants to do something else with it? Sure, they could do something obfuscated like tie STDOUT so its output goes into a variable, but the idea here (assuming this is not for obfuscation) is to not require the caller to do things like that.

    well; then you just have to change print $result; with $_ = $result; I suppose... But i don't know how the $_ variable is handled with packages (yeah it's my first one) so, if you could tell me if it's the right way to re use the encrypted string...


      Er... no. return $result; Then, caller could do (after importing the functions) $ciphertext = acrypt($plaintext, $key); (or similarly for adecrypt). See perlvar, perlmod, perlsub.
