An interesting comment from Snowden

[guohua]

@senona PGP is the most common method of encryption.  It stands for Pretty Good Privacy (nice huh?), and has been around for a while. Now it has become commercial but there is a free version called GnuPG. 

There are other ways as well to use PGP, eg Thuderbird (mail client) and Enigmail, you just need then everyone else to be using PGP so you can encrypt your emails to them, well yoiu can encrypt them anyway but without your public key and PGP they will be unable to read the email

Yes, GnuPG is a Very Good program.
But getting others to be in the same frame of mind and worried about their Personal information will drive you crazy.
The older you are the more you understand, No One Will Take Care Of You Nor Do They Care!
The younger Sheeple (up to 30 something) think that the Government and Mark Elliot Zuckerberg (facebook) and others Care About Them,,, YES, Really!
