SVC_HMACSHA1Update

Syntax

#include <twl/os/common/systemCall.h>
void SVC_HMACSHA1Update( SVCHMACSHA1Context *context,
                          const void* data,
                          u32 len );

Arguments

context Pointer to the context structure for HMAC-SHA1 generation.
data Pointer to the input data.
len Size of the input data.

Return Values

None.

Description

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.
