How to set up email encryption in cPanel

This guide explains how to set up email encryption in cPanel. The Encryption interface in cPanel allows you to generate and manage GnuPG/OpenPGP keys that can be used for encrypted email communication. To actually encrypt and decrypt email messages, these keys must be used with compatible email clients or other supported applications.

Follow the steps:

Log in to cPanel.
Select the “Email” section and click on the “Encryption” sub-option.
You will head towards a new page. Fill the form as given below-
1. Enter the name in the “Your Name” field.
2. Enter email address under the “Your Email” field.
3. Add a “Comment or Nickname”.
4. Enter the “Key Password” and then again “Confirm Password”. Remember to add a strong password. You can leverage a “Password Generator”.
5. In the “Expiration Date” field, specify a period for the keys to remain valid. Use “0” for no expiration, and years, weeks, or days, respectively.
6. Next, select a “Key Size.”
  Note- A larger key size improves mathematical security. However, a 2048-bit key is generally sufficient. Note that larger key sizes may lead to issues with unsupported systems or recipients.
  Note: Some WordPress installations restrict .js file uploads through the Media Library for security reasons. If the upload is blocked, you may need to allow the JavaScript MIME type, use a plugin that supports custom JavaScript, or add the script through your theme or website management tools instead.
7. Click the “Generate Key” button. It may take a moment to generate the key.
8. Upon success, you will receive a message stating, “The Key has been successfully created.”
  Note: Generating a GnuPG/OpenPGP key in cPanel does not automatically encrypt your email messages. To send and receive encrypted emails, you must configure and use a compatible email client or application that supports GnuPG/OpenPGP encryption and import the appropriate keys.
9. Finally, refresh the page and scroll to the bottom.
