When you need to keep your email messages private, encrypting it is one of the safest ways to do this.

The cPanel interface allows you to create, manage and save GnuPG keys. GnuPG keys use the public key approach for encryption

Programs that use GnuPG keys encrypt outbound email messages with a public key. In this way only the intended recipient that possess the private key, can decrypt and read the message.

Creating a New Key


To add a GnuPG key follow these steps:

  • 1) Enter your information in the Create a New Key text boxes
  • 2) Select the key size, in bits, from the Key Size menu. The key size defaults to 2048.
  • 3) Click "Generate Key"

The system defaults to one year (1year) if you do not set your own expiration date

Use a secure password. A secure password may contain uppercase and lowercase letters, numbers, and symbols.

After you create a new GnuPG key, you can add the key to other programs or interfaces that require GnuPG keys, for example, a mail client.

Import a key

To import an existing GnuPG key, follow these steps:

  • 1) Copy and paste the GnuPG key into the available text box.
  • 2) Click "Import"

The system will then add the key to your server

Delete or View Your Keys

After you add a GnuPG key set to the Web Server, you can delete it or view it in the Public Keys or Private Keys tables.

Delete a key

To delete a GnuPGkey, follow these steps:

  • 1) Locate the key that you wish to delete in the Public Keys or Private Keys tables.
  • 2) Click "Delete GnuPG Key" for that key. A new interface will appear.
  • 3) Click Yes. A success or error message will appear.

You must delete a private key before you delete the corresponding public key.

View a key

To view a GnuPG key, follow these steps:

  • 1) Locate the certificate that you wish to edit in the Certificates on Server table
  • 2) Click "View". A new interface will appear that displays the GnuPG key block
  • 3) Click Go Back to return to the Encryption interface.
