Description
B_VerifyFinal finalizes the digesting process for algorithmObject and verifies the digital signature supplied by signature of signatureLen bytes. The algorithm object for supplying random numbers is randomAlgorithm; it may be (B_ALGORITHM_OBJ)NULL_PTR for signature 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
, so that another verifying process may be performed. See
