Public Methods

Method	Description
DecryptBlock ( byte inputBuffer, int inputOffset, int inputCount, byte outputBuffer, int outputOffset ) : int	Decrypts the specified region of the input byte array and copies the decrypted data to the specified region of the output byte array.
EncryptBlock ( byte inputBuffer, int inputOffset, int inputCount, byte outputBuffer, int outputOffset ) : int	Encrypts the specified region of the input byte array and copies the encrypted data to the specified region of the output byte array.
TwofishCipher ( byte key, CipherMode mode, CipherPadding padding ) : System	Initializes a new instance of the TwofishCipher class.
