Dynamic channels are valid for this request. A channel value of zero is valid.

NUM_MDHA_DESC defines the number of descriptors within the DPD_HASH_LDCTX_HASH_ULCTX_GROUP

that use this request.

DPD_HASH_LDCTX_HASH_ULCTX_GROUP (0x4400) defines the group for all descriptors within this

request.

Table 24. HASH_REQ Valid Descriptors (0x4400) (opId)

Descriptors Value Function Description

DPD_SHA256_LDCTX_HASH_ULCTX 0x4400 Load context in a dynamic channel to using an

SHA-256 hash algorithm then get the resulting context

DPD_MD5_LDCTX_HASH_ULCTX 0x4401 Load context in a dynamic channel to using an MD5

hash algorithm then get the resulting context

DPD_SHA_LDCTX_HASH_ULCTX 0x4402 Load context in a dynamic channel to using an SHA-1

hash algorithm then get the resulting context

DPD_SHA256_LDCTX_IDGS_HASH_ULCTX 0x4403 Load context in a dynamic channel to using an

SHA-256 IDGS hash algorithm then get the resulting

context

DPD_MD5_LDCTX_IDGS_HASH_ULCTX 0x4404 Load context in a dynamic channel to using an MD5

IDGS hash algorithm then get the resulting context

DPD_SHA_LDCTX_IDGS_HASH_ULCTX 0x4405 Load context in a dynamic channel to using an SHA-1

IDGS hash algorithm then get the resulting context
