B_KeyAgreePhase1
326 RSA BSAFE Crypto-C Library Reference Manual
B_KeyAgreePhase1
Description
B_KeyAgreePhase1 uses
algorithmObject
to generate the initial value for the other
party, writing it to
output,
which is a buffer supplied by the caller of at least
maxOutputLen
bytes, and setting
outputLen
to the number of bytes written to
output
.
The algorithm object for supplying random numbers is
randomAlgorithm
. 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. See
B_KeyAgreeInit.
Return value
int B_KeyAgreePhase1 (
B_ALGORITHM_OBJ algorithmObject, /* algorithm object */
unsigned char *output, /* output data buffer */
unsigned int *outputLen, /* length of output data */
unsigned int maxOutputLen, /* 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”
