In this post, we will show how to configure Horde Groupware to use email encryption.
Horde Groupware is a free webmail program that you can access via cPanel at yourdomainname.com/webmail.
We will assume that you already generated your key pair in cPanel->Encryption. Look at this KB post: Create public and private GnuPG keys for email encryption in cPanel
- Login with your credentials at yourdomain.com/webmail and select the Horde option.
2. From the Horde menu go to Preferences->Mail
3. Then choose PGP
4. On the PGP page, check the Enable PGP functionality? option and click Save.
5. Now on the Horde PGP page you will see more options.
- Use the Import Public Key button to import public keys. A new entry will be created in the Address Book – entry that will contain the public key of that email.
- Use the Import Key button to import your private key. It will be used to encrypt messages that you send.
Do not give your private key to anyone! Send only your public key.
6. When sending messages you can select if you want to encrypt or not the message. Don’t forget that only recipients that have your public key will be able to read the messages you choose to encrypt.
A public/private key looks like:
