4.6.5 HMAC Request Structures
The following sections provide structure definitions for HMAC requests.
4.6.5.1 HMAC_PAD_STATIC_REQ
unsigned long opId;
unsigned long channel;
PMPC18x_NOTIFY_ROUTINE notify;
PMPC18x_NOTIFY_CTX pNotifyCtx;
PMPC18x_NOTIFY_ON_ERROR_ROUTINE notify_on_error;
MPC18x_NOTIFY_ON_ERROR_CTX ctxNotifyOnErr;
int status;
void* nextReq;
unsigned long keyBytes;
unsigned char* keyData;
Dynamic channels are not valid for this request. A channel value of zero is invalid.
NUM_HMAC_STATIC_PAD_DESC defines the number of descriptors within the DPD_HMAC_SA_PAD_GROUP
that use this request.
DPD_HMAC_SA_PAD_GROUP (0x4600) defines the group for all descriptors within this request.
Table 26. HMAC_PAD_STATIC_REQ Valid Descriptors (opId)
Descriptors Value Function Description
DPD_HMAC_SA_SHA256_PAD 0x4600 Perform a HMAC operation on a static channel to using
an SHA-256 hash algorithm with padding
DPD_HMAC_SA_MD5_PAD 0x4601 Perform a HMAC operation on a static channel to using
an MD5 hash algorithm with padding
DPD_HMAC_SA_SHA_PAD 0x4602 Perform a HMAC operation on a static channel to using
an SHA-1 hash algorithm with padding
DPD_HMAC_SA_SHA256_PAD_IDGS 0x4603 Perform a HMAC operation on a static channel to using
an SHA-256 hash algorithm with IDGS padding
DPD_HMAC_SA_MD5_PAD_IDGS 0x4604 Perform a HMAC operation on a static channel to using
an MD5 hash algorithm with IDGS padding
DPD_HMAC_SA_SHA_PAD_IDGS 0x4605 Perform a HMAC operation on a static channel to using
an SHA-1 hash algorithm with IDGS padding
