NUM_HMAC_PAD_DESC defines the number of descriptors within the DPD_HASH_LDCTX_HMAC_ULCTX_GROUP that
use this request.
DPD_HASH_LDCTX_HMAC_ULCTX_GROUP (0x4A00) defines the group for all descriptors within this request.
Table 12. HASH_REQ Valid Descriptors (0x4500) (opId)
Descriptors Value Function Description
DPD_SHA256_LDCTX_HASH_PAD_ULCTX 0x4500 Compute digest with pre-padded data using an
SHA-256 hash algorithm then store the resulting
context

SHA-1 hash algorithm then store the resulting context
DPD_SHA256_LDCTX_IDGS_HASH_PAD_ULCTX 0x4503 Compute digest with pre-padded data using an
SHA-256 IDGS hash algorithm then store the
resulting padded context
