EncryptUpdate Method

Encrypts the next block of data.

Syntax

ANSI (Cross Platform)
char* EncryptUpdate(const char* lpBuffer, int lenBuffer, int *lpSize = NULL);

Unicode (Windows)
LPSTR EncryptUpdate(LPCSTR lpBuffer, INT lenBuffer, LPINT lpSize = NULL);
- (NSData*)encryptUpdate:(NSData*)buffer;
#define MID_SYMMETRICCRYPTO_ENCRYPTUPDATE 14

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

Remarks

Use this method to encrypt the next block of data contained in Buffer.

Call this method after calling EncryptInit for as many times as needed, until the wholevolume of data is processed. Having done that, call EncryptFinal to complete the encryptionand get the terminating encrypted trailer.

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.
