GnuPG

Gnupg is a tool that helps you keep your secrets safe. You know how you have a secret diary where you write all your secrets? Gnupg helps you keep your online secrets safe in the same way.

Sometimes, you will write a message that you only want your friend to read, but you don't want anyone else to see it. Gnupg makes that message secret by turning it into a secret code that only your friend can read.

Just like you need a key to open your diary, your friend needs a key to read the secret message. Gnupg helps you create these keys and keeps them safe so that only the right people can read your secrets.
