Section 8.2.2 says:
Similar to item (9), (16), and (17) above, the Description of SHA224_256ResultN contains improper wording. Additionally, counting 28/32 elements as ranging from the "0th" up to the "28th/32nd" is unpleasant and wrong -- that erroneously indicates 29/33 elements (octets) ! Near the bottom of page 44, the RFC says: * Description: * This helper function will return the 224-bit or 256-bit message * digest into the Message_Digest array provided by the caller. * NOTE: The first octet of hash is stored in the 0th element, * the last octet of hash in the 28th/32nd element. For correctness and consistency, it should say: * Description: * This helper function will return the 224-bit or 256-bit message * digest into the Message_Digest array provided by the caller. * NOTE: * The first octet of the hash is stored in the element with index 0, * the last octet of the hash in the element with index 27/31.
