Method Details

DecryptBlock() public method

Decrypts the specified region of the input byte array and copies the decrypted data to the specified region of the output byte array.
public DecryptBlock ( byte inputBuffer, int inputOffset, int inputCount, byte outputBuffer, int outputOffset ) : int
inputBuffer byte The input data to decrypt.
inputOffset int The offset into the input byte array from which to begin using data.
inputCount int The number of bytes in the input byte array to use as data.
outputBuffer byte The output to which to write decrypted data.
