GnuPG is a publicly available encryption scheme that uses the "public key" approach. With GnuPG, messages are encrypted using a "public key" however, they can only be decrypted by a "private key", which is retained by the intended recipient of the message.
- Login to cPanel and click on the GnuPG Keys icon in the Security section.
- Next, to Your Name, enter the name you want to be seen during secure communications.
- Next, to Your Email, enter the full email address you will use with the pair of keys.
- Next to Comment/Nickname, enter a short reminder about the purpose of this key pair.
- Next to Key Password, enter the password you desire for the encryption. Be sure to enter the same password, again, on the next line.
- Next to Expire Date, enter a value in years or weeks or days, but not a combination of those. So, if you need 1 year and 3 weeks, enter "55w". If you need 1 year, 3 weeks, and 2 days, enter "388d".
- Next to Key Size, select the size of the encryption key. A bigger number means better encryption.
- Hit the "Generate Key" button and you will be able to view both keys.
