The **Encryption** tool uses GnuPG (GNU Privacy Guard) to create encryption keys, so you can exchange email that only the intended recipient can read. GnuPG uses a matched pair of keys: a **public key** that you share with people so they can encrypt messages to you, and a **private key**, kept secret, that you use to decrypt those messages.

## Open the Encryption tool

Log in to cPanel and, in the **Email** section, click **Encryption**.

## Generate a new key

In the **Create a New Key** section, fill in:

- **Your Name** - the name to attach to the key.
- **Your Email** - the email address the key is for.
- **Comment or Nickname** - an optional label to help you identify the key.
- **Key Password** and **Confirm Password** - a strong passphrase that protects the private key. Use the **Password Generator** if you would like cPanel to create one.
- **Expiration Date** - choose **1 Year**, or select **Do not expire**.
- **Key Size** - a larger key is more secure; `2048` is a sensible default.

When you are happy, click **Generate Key**. cPanel creates the key pair and lists it on the page, where you can view the public key to share it, or delete the key later.

:::tip
Share your **public** key freely so others can send you encrypted email, but never share your **private** key or its password - they are what keep your messages secure.
:::

You can also bring in a key you already hold using the **Import Key** section further down the page.
