GnuPG keys use the public key approach for encryption. Programs that use GnuPG keys encrypt outbound messages with a public key. Only the intended recipient, who possesses the private key, can decrypt the message. # Create a New Key To add a GnuPG key, perform the following steps: 1. Enter your information in the *Create a New Key* text boxes. !! Important\ Use a secure password. A secure password is **not** a dictionary word, and it contains uppercase and lowercase letters, numbers, and symbols. !! Note\ Use an appropriate expiration date for your key. The system defaults to one year (`1y`). 1. Select the key size, in bits, from the *Key Size* menu. The key size defaults to *2048*. 2. Click *Generate Key*. 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, perform the following steps: 1. Copy and paste the GnuPGkey into the available text box. 2. Click *Import*. The system will add the key to your server. # Delete or view keys After you add a GnuPG key set to the server, you can delete it or view it in the *Public Keys* or *Private Keys* tables. ## Delete a key To delete a GnuPGkey, perform the following 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. !! Important\ You must delete a private key before you delete the corresponding public key. ## View a key To view a GnuPG key, perform the following 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. !! More !! For more information on how to install encryption keys for your specific mail client, refer to their documentation: !!
