What are GnuPG Keys?

GnuPG allows you to encrypt and sign data. This means that any data you transmit that is encrypted with your GnuPG public key, can only be decoded with your GnuPG private key. This means that you can provide your public key for others to encrypt information and send it to you but only you can decrypt that information. Please be careful to never give out your private key because this will allow anyone to read your encrypted data. you can find out more about GnuPG Keys here.
