 You can retrieve the {% data variables.product.prodname_dotcom %} secret scanning public key from https://api.github.com/meta/public_keys/secret_scanning and validate the message using the `ECDSA-NIST-P256V1-SHA256` algorithm. The endpoint

 The following code snippets demonstrate how you could perform signature validation.
 The code examples assume you've set an environment variable called `GITHUB_PRODUCTION_TOKEN` with a generated [{% data variables.product.pat_generic %}](https://github.com/settings/tokens) to avoid hitting rate limits. The {% data variables.product.pat_generic %} does not need any scopes/permissions.
