void SVC_HMACSHA1Update( SVCHMACSHA1Context *context,
const void* data,
u32 len );
| context | Pointer to the context structure for HMAC-SHA1 generation. |
| data | Pointer to the input data. |
| len | Size of the input data. |
None.
This function updates the HMAC-SHA1 digest value based on the input data.
context must be initialized beforehand with SVC_HMACSHA1Init().
Call this function as many times as needed, and then use the SVC_HMACSHA1GetHash function to obtain the digest value. Specify the input data using data and len. Any size and alignment position can be used.
