RSA Security 5 manual Int BDecryptFinal

B_DecryptFinal

B_DecryptFinal

int B_DecryptFinal (
B_ALGORITHM_OBJ	algorithmObject,	/* algorithm object */
unsigned char	*partOut,	/* output data buffer */
unsigned int	*partOutLen,	/* length of output data */
unsigned int	maxPartOutLen,	/* size of output data buffer */
B_ALGORITHM_OBJ	randomAlgorithm,	/* random byte source */
A_SURRENDER_CTX *surrenderContext		/* surrender context */
);

Description

B_DecryptFinal finalizes the decrypting process specified by algorithmObject, writing any remaining decrypted output to partOut, which is a buffer supplied by the caller of at least maxPartOutLen bytes, and setting partOutLen to the number of bytes written to partOut. The algorithm object for supplying random numbers is randomAlgorithm; it may be (B_ALGORITHM_OBJ)NULL_PTR for decrypting algorithms that do not need random numbers. The surrender context for processing and canceling during lengthy operations is surrenderContext; if its value is (A_SURRENDER_CTX *)NULL_PTR, Crypto-C does not use it. algorithmObject is reset to the state it was in after the call to B_DecryptInit, so that another decrypting process may be performed. See B_DecryptInit.
