Practical public-key cryptography with GnuPG, part 1 of 2

These days you simply can’t just ignore privacy issues on the Internet. Good news is that there are certain, mathematically proven, super-strong methods of encryption, which you can readily apply whenever you feel that the privacy of your communications is of paramount importance.

The method of encryption we’re talking about is based on public-key cryptography, and the freely available tool we can use to apply those methods is the GNU Privacy Guard. In this two-part mini-series we first discuss the ideas behind public-key crypto. We then go on to learn how we can actually benefit from these ideas with the use of GnuPG. Thanks to that wonderful software suite we can strongly encrypt our email or any kind of file, and be absolutely certain that only the intended recipients will be able to read our email or open our files.
