Unicode (Windows)
LPSTR EncryptBlock(LPCSTR lpInputBuffer, INT lenInputBuffer, LPINT lpSize = NULL);
- (NSData*)encryptBlock:(NSData*)inputBuffer;
#define MID_RC4_ENCRYPTBLOCK 6

IPWORKSENCRYPT_EXTERNAL int IPWORKSENCRYPT_CALL IPWorksEncrypt_RC4_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

EncryptBlock will encrypt the input data and return the encrypted block. The encrypted block will always be the same length as the decrypted data. The following properties are applicable:

  • IV (required)
  • Key (required)

InputBuffer specifies the input data to encrypt.

Error Handling (C++)

This method returns a Binary String 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.
