Uploading Your Key Pair {#uc-upload-key}
========================================

When you have generated your encryption key pairs, you can upload your key to the `Unified Checkout` platform. Keys can be loaded at any hierarchy that is enabled for them and are used for all child entities that do not have keys loaded. You can upload a key at parent and child levels, but child keys override parent keys.  
Follow these steps to upload your key pair:

1. Navigate to Payment Configuration \> Unified Checkout. The `Unified Checkout` configuration page opens.

3. Upload the public encryption key in JWK format, and click Save.
