HashFile Method

Calculates a message digest over data contained in a file.

Syntax

ANSI (Cross Platform)
char* HashFile(const char* lpszSourceFile, int *lpSize = NULL);

Unicode (Windows)
LPSTR HashFile(LPCWSTR lpszSourceFile, LPINT lpSize = NULL);
- (NSData*)hashFile:(NSString*)sourceFile;
#define MID_HASHFUNCTION_HASHFILE 5

SECUREBLACKBOXLITE_EXTERNAL int SECUREBLACKBOXLITE_CALL SecureBlackboxLite_HashFunction_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

This method calculates and returns a message digest over the data contained in file SourceFile. This is a quick way to calculate a hash over a file content in one go.

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.
