Hi PerlMonks,

I have a perl script which I'd like to encrypt before it is further distributed, I came across the "Module::Crypt" module and now i'm trying to install it but running into errors, please see below the cpan install log.

My Questions are:

1- Is "Module::Crypt" good enough to encrypt a perl script?

2- Would the script's execution slow down after it is encrypted?

3- I couldn't find good info or examples on how to use this module, can you please help share any info you have on the Crypt module?

Thank You...!
