Email Encryption:

The email encryption in cPanel protects your outgoing email messages from reaching unauthorized recipients. When an encrypted message is sent, then the recipient needs to decrypt it with a private key. It enhances the message security and privacy as other readers will not be able to read the message. The sender encrypts the message using ‘public key’ and the corresponding recipient can decrypt it with ‘private key’.

cPanel uses the feature GNU Privacy Guard or GnuPG for creating keys to encrypt the messages. It utilizes two ways such as the public and private key cryptography scheme. It ensures email security to prevent sensitive information. The below steps helps to create email encryption on your cPanel account by using GnuPG cryptographic algorithms.

Steps to Encrypt Email Using cPanel:

Step 1: Login to the cPanel with username and password.
