Function request_digest_unsigned
pub fn request_digest_unsigned(
nonce: &RequestNonce,
payload: &[u8],
) -> RequestDigestExpand description
The request digest of a response to an unsigned request: SHA-256
over the 16 nonce bytes followed by the request payload exactly as
received (empty for a bodiless request), marked
RequestKind::Unsigned. The nonce has a fixed length, so the split
between the two is unambiguous.
