Sigh. You can't encrypt Perl scripts.
Well, you can, but it won't help. At least not against someone who is bored, has a little bit of spare time, or a little bit of motivation.
In any case, you have to deliver the encypted script, the decryption key, and the decryption algorithm. Delivering all three part means that anyone can replace the call to "evaluate this script" with "print this script". Omit any of the three parts and you can not execute the script. There is no way to change that.
Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)
