Message Level Encryption {#wc-message-level-encryption}
=======================================================

Message-Level Encryption (MLE) enables you to store information or communicate with other parties while helping to prevent uninvolved parties from understanding the stored information. MLE is optional and supported only for payments services. A REST certificate is required for MLE.  
Follow these steps to enable MLE,:

1. Check **Message Level Encryption**.
2. Enter the **Key Directory Path** where you have stored the certificate in your `WooCommerce`/WordPress environment.
3. Enter the **Key File Name**.
4. Enter the **Key Password** which you set when generating the REST certificate.
