B_DecryptFinal
300 RSA BSAFE Crypto-C Library Reference Manual
B_DecryptFinal
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.
Return value
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 */
);
Value Description
0 Operation was successful.
non-zero see Appendix A, ”Crypto-C Error Types”
