…in bytes preceding. Hashes are computed in accordance with [FIPS-180-4] A HMAC [RFC2104] is encoded as a hash. The size of the hash and HMAC functions used in the protocol depend on the size of the keys used for device and owner attestation. The following table lists the mapping.…

…6 To sign and verify using this algorithm, the signer applies the HMAC function RFC2104 with the shared signing key ( ) and the signature base ( text ) ( Section 2.5 ). The hash function SHA-256 RFC6234 is applied to the signature base to create the digest content to which the HM…
