CounterSignature

A signed receipt transmitted in the synchronous Ack response body, proving that the receiver authenticated, received, and processed the inbound request.

CounterSignature shares the same wire format as Signature but differs:

• Signer: the response receiver (not the request sender)
• Location: transmitted in the Ack response body (not in the Authorization header)
• digest: covers the Ack response body (not the inbound request body)
• (request-digest) and (message-id) MUST be included in the signing string

Signing string format:

(created): {unixTimestamp}
(expires): {unixTimestamp}
digest: BLAKE-512={base64DigestOfAckBody}
(request-digest): BLAKE-512={base64DigestOfInboundRequestBody}
(message-id): {messageId}
