One tip: DO NOT USE Online tools, like the ones shown in the right-hand column. Download the PGP software onto your computer and learn to use it. The previous poster was absolutely right -- PGP is likely to save your ass, so don't cut corners when learning how to use it. Read the Darknet user's Bible -- it has a section on using PGP.
Rock-it like its hot.
Do you have a PGP Public Key?
