GnuPG

The ease of use is one of the best feature in this product. It is very easy to guide a very new user through usage of this tool, and a quick 2 minutes demo is enough to start using this. I personally like the speed of encrypting/decrypting files.

GnuPG worked well for users who were familiar with the software. I used this program on a daily basis when I was responsible for handling digital codes with a large monetary value.

- Steady workhorse encryption, available on every/any platform. - Can automated and used to sign tings like data from sensors, processes, etc. - Doesn't require an expensive enterprise tool suite to run and can even be embedded inside applications. -
