GnuPG keys use the “public key approach” to encryption. Messages are sent once they have been encrypted by a public key. The messages can only be decrypted by a private key, held by the intended recipient.
Add a Key
To add a GnuPG key:
• Fill in the fields below the Create a New Key heading.
• Click Generate Key.
Make sure to use an appropriate expiration date. The expiration date is defined in years and describes when the key will no longer work; 1 year is the default.
Remember: Use a secure password. A secure password is one that is not a dictionary word and contains upper- and lower-case letters, numbers, and symbols.
Import a GnuPG Key
An existing key can be imported using the Import Key button.
To import a GnuPG key:
• Copy and paste the key into the available text box.
• Click Import.
The key will automatically be installed onto your web server.
Delete or View a GnuPG Key
Once a key-set has been added to the server, it can be deleted or viewed for copy from the main GnuPG page under the Public Keys and Private Keys heading.
