Re: 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...

thx

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