i downvoted you because this question shows no work on your part.

A few thoughts:

• It is presumptuous to assume that everyone knows about CPAN.
• Even if he did know about CPAN, he could have run into other problems (search was down, etc.) or he was just looking for opinions on the Crypt::* modules, which brings us to our next point.
• When reading a post, remember english isn't everyone's first language. Just because a post seems poorly worded to you doesn't mean the poster was lazy.
• I like short, to the point questions. Five paragraphs of irrelevant background information just distracts from the actual question.

As for the original question: see derby's Getting Started with GnuPG and GPG and The GNU Privacy Handbook.
