Securing Communication: A Guide to Encryption in cPanel

cPanel supports GnuPG, an open-source software that uses cryptographic algorithms to encrypt and decrypt messages. It uses public and private key infrastructure to enhance the security of sensitive emails by allowing the sender to encode the message using the recipient’s public key and decrypt it using the recipient’s private key.

a) How to create a GnuPG key in cPanel

1. Log into cPanel and navigate to the Email section to select Encryption tool or search for the Encryption tool in the search bar.

2. Then, enter your name, email and a comment or nickname to differentiate between multiple keys.

3. After that, enter a strong-key password and specify a specific date to set an expiration date like:

• y represents the year; 1y represents 1 year.
• w means week; 2w means 2 weeks.
• d stands for day; 4d stands for 4 days.

4. Next, select a secure key size from the drop-down list, as larger sizes are more secure.

5. Finally, click the “Generate Key” button and it will take a few minutes to generate the key.

b) How to import a key in cPanel

1. Log into cPanel and navigate to the Email section to select Encryption tool or search for the Encryption tool in the search bar.
