This recipe enables you to sign and verify messages received from external systems using either Oracle or customer-managed keys in OCI Vault.

The recipe uses the OCI Vault REST APIs to sign and verify messages received from external applications. It contains two integration flows:

• Sign Message: Accepts message in string format as part of the request payload and invokes the OCI Vault Sign REST API, which generates a message signature and sends the signed message as part of the response.
• Verify Message: Accepts signed message as part of the request payload and invokes the OCI Vault Verify REST API, which verifies the message signature and sends the response as true or false.
