Security Engine (SEC) 3.0
To generate an HMAC for a message that is spread across a sequence of descriptors, the following mode
register bit settings should be used:
All descriptors other than the final descriptor must output the intermediate message digest for the next
descriptor to reload as MDEU context.
SSL-MAC operations cannot be spread across a sequence of descriptors.
Additional information on descriptors can be found in
10.7.6.4

HMAC generation. MDEU supports at most one block of key. MDEU generates a key size error if the
value written to this register exceeds 64 bytes for MD5, SHA-1, SHA-224, or SHA-256. If algorithms
SHA-384 or SHA-512 are selected, then MDEU generates a key size error if the value written to this
register exceeds 128 bytes.
