void SVC_SHA1Update( SVCSHA1Context *context,
const void* data,
unsigned long len );
| context | Pointer to the context structure used for SHA-1 generation. |
| data | Pointer to the input data. |
| len | Size of the input data. |
None.
This function updates the SHA-1 digest value based on the input data.
context must be initialized beforehand with SVC_SHA1Init().
Call this function as many times as needed, and then use the SVC_SHA1GetHash function to obtain the digest value. Specify the input data using data and len. Any size and alignment position can be used.
SHA-1 is an algorithm to find the message digest value. For details, see RFC (Request For Comments) 3174, which is published by IETF (the Internet Engineering Task Force).
