This article describes how to manage email encryption with GNU Privacy Guard keys in cPanel.
The GNU Privacy Guard, also known as GnuPG or GPG, is an open-source implementation for public-key cryptography. Public-key cryptography systems use public and private keys (keypairs) to encrypt and decrypt e-mail messages, files, and so on. Senders use recipients' public keys to encrypt items, and recipients use their own private keys to decrypt the items.
You can easily create, import, view, and delete keys by using cPanel.
To use GnuPG encryption, you must first create a new keypair.
To create a new GnuPG keypair, follow these steps:
In the Comment or Nickname text box, type a comment or nickname for the key.
In the Password (Again) text box, retype the password.
In the Key Size list box, select a key size.
If you already have a keypair, you can import your public key.
To import a public key, follow these steps:
Copy and paste the key text into the text box.
When you copy and paste the key text, make sure that you include the beginning and ending lines of the key:
-----BEGIN PGP PUBLIC KEY BLOCK----- Key data -----END PGP PUBLIC KEY BLOCK-----
You can view or delete keys that you have created or imported.
To view or delete a key, follow these steps:
Locate the key that you want to view or delete. For each email address there will be a private key and a public key.
