int CRYPT_SHA384_DataAdd(
CRYPT_SHA384_CTX* sha384,
const unsigned char* input,
unsigned int sz
);
This function updates the hash with the data provided.
The SHA384 context must be initialized prior to the first call of this function. The context must not be modified by code outside of this function.
| Parameters | Description |
|---|---|
| sha384 | Pointer to CRYPT_SHA384_CTX structure which holds the hash values. |
| input | Pointer to the data to use to update the hash. |
| sz | Size of the data (in bytes) to use to update the hash. |
BAD_FUNC_ARG - An invalid pointer was passed to the function, either in sha384 or input.
0 - An invalid pointer was not passed to the function.
In order to preserve the validity of the SHA384 hash, nothing must modify the context holding variable between calls to CRYPT_SHA384_DataAdd.
