Decrypt an Information Message Body

The Decrypt Information Message feature allows you to decrypt the body of a Secure Channel information message. If an authenticator instance is activated, the integrating application is able to send Secure Channel messages that can be decrypted and parsed via the OneSpan Cloud Authentication REST API. Such messages are generally considered as information messages sent by the client to the server. The body of such a Secure Channel information message contains a payload which is encrypted with the payload key of an MDL authenticator instance. The information message body is decrypted with the following endpoint:

• POST /authenticators/{serialNumber}/decrypt-information-message

This endpoint accepts informationMessage as payload, the responses include:

• 200: Decrypted information message.

• 400: The input is invalid.

• 404: Authenticator not found.

• 409: Failed to decode information message.

• 500: Unexpected server error.
