Finish Method

Completes the hash and returns the resulting message digest.

Syntax

• C++
• Objective-C
• C

ANSI (Cross Platform)
char* Finish(int *lpSize = NULL);

Unicode (Windows)
LPSTR Finish(LPINT lpSize = NULL);

- (NSData*)finish;

#define MID_HASHFUNCTION_FINISH 3

SECUREBLACKBOX_EXTERNAL int SECUREBLACKBOX_CALL SecureBlackbox_HashFunction_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

This method finalizes the hashing operation and returns the message digest of the input data. Use it in conjuction with Reset and Update methods to process data in chunks.

Error Handling (C++)

This method returns a Byte Array value (with length lpSize); after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
