       ## Introduction
       
       I don't use gpg a lot but it seems the only tool out there for
       encrypting data
       which "works" and widely used.
       
       So this is my personal cheatsheet for everyday use of gpg.
       
       In this post, I use the command `gpg2` which is the binary to GPG
       version 2.
       On your system, "gpg" command could be gpg2 or gpg1.
       You can use `gpg --version `if you want to check the real version
       behind gpg
       binary.
       
       In your *~/.profile* file you may need the following line:
       
           export GPG_TTY=$(tty)
       
       
       ## Install GPG
       
       The real name of GPG is GnuPG, so depending on your system the package
       can be
       either gpg2, gpg, gnupg, gnugp2 etc...
       
       On OpenBSD, you can install it with: `pkg_add gnupg--%gnupg2`
       
       
       ## GPG Principle using private/public keys
       
       - YOU make a private and a public key (associated with a mail)
       - YOU give the public key to people
       - PEOPLE import your public key into they keyring
       - PEOPLE use your public key from the keyring
       - YOU will need your password everytime
       
       I think gpg can do much more, but read the manual for that :)
       
       
       ## Initialization
       
       We need to create a public and a private key.
