This feature allows you to create, store, and manage GnuPG keys. 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.
Use an appropriate expiration date for your key. The system defaults to one year (1year)

2) Select the key size, in bits, from the Key Size menu. The key size defaults to 2048.

3) Click "Generate Key"

Important: Use a secure password. A secure password is not a dictionary word, and it contains 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, perform the following 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 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.
