Implements CAST cipher algorithm

Inheritance: BlockCipher

Public Methods

Method	Description
CastCipher ( byte key, CipherMode mode, CipherPadding padding ) : System	Initializes a new instance of the CastCipher class.
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.

Method	Description
Bits32ToInts ( uint inData, int b, int offset ) : void
CastDecipher ( uint L16, uint R16, uint result ) : void
CastEncipher ( uint L0, uint R0, uint result ) : void	Does the 16 rounds to encrypt the block.
F1 ( uint D, uint Kmi, int Kri ) : uint	The first of the three processing functions for the encryption and decryption.
F2 ( uint D, uint Kmi, int Kri ) : uint	The second of the three processing functions for the encryption and decryption.
F3 ( uint D, uint Kmi, int Kri ) : uint	The third of the three processing functions for the encryption and decryption.
IntsTo32bits ( int b, int i ) : uint
SetKey ( byte key ) : void	Sets the subkeys using the same nomenclatureas described in RFC2144.

Initializes a new instance of the CastCipher class.
