void SVC_SHA1GetHash( SVCSHA1Context *context,
void* md );
| context | Pointer to the context structure used for SHA-1 generation. |
| md | Pointer to the memory location that holds the message digest value. |
None.
Gets the digest value using SHA-1.
Use the SVC_SHA1Init function to initialize the context argument and then use the SVC_SHA1Update function to provide the input data.
The length of the generated message digest value is 160 bits, or SVC_SHA1_DIGEST_SIZE (= 20) bytes. Use the md argument to pass an area that can store a value of this size.
This function rewrites context internally, so you cannot continue to use the same context with the SVC_SHA1Update function.
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).
