HMAC-SHA2 (husha2.h)

Here, SHA-2 is used to produce a MAC tag value.

The HMAC-SHA-2 MAC tag lengths are defined in husha2.h as follows:

SB_HMAC_SHA224_224_TAG_LEN
SB_HMAC_SHA224_112_TAG_LEN
SB_HMAC_SHA256_256_TAG_LEN
SB_HMAC_SHA256_128_TAG_LEN
SB_HMAC_SHA384_384_TAG_LEN
SB_HMAC_SHA384_192_TAG_LEN
SB_HMAC_SHA512_512_TAG_LEN
SB_HMAC_SHA512_256_TAG_LEN

hu_HMACSHA224Begin()
