int CRYPT_SHA_Finalize(
CRYPT_SHA_CTX* sha,
unsigned char* digest
);
This function finalizes the hash and puts the result into digest.
The SHA context must be initialized prior to calling this function. The context must not be modified by code outside of this function.
| Parameters | Description |
|---|---|
| sha | Pointer to CRYPT_SHA_CTX structure which holds the hash values. |
| digest | Pointer to byte array to store hash result. |
BAD_FUNC_ARG - An invalid pointer was passed to the function. either sha or digest.
0 - An invalid pointer was not passed to the function.
In order to preserve the validity of the SHA hash, nothing must modify the context hoding variable between calls to CRYPT_SHA_DataAdd and CRYPT_SHA_Finalize.
