C# Class Renci.SshNet.Security.Cryptography.Ciphers.DesCipher

Implements DES cipher algorithm.

Inheritance: BlockCipher

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.
DesCipher ( byte key, CipherMode mode, CipherPadding padding ) : System	Initializes a new instance of the DesCipher class.
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
DesFunc ( int wKey, byte input, int inOff, byte outBytes, int outOff ) : void	Performs DES function.
GenerateWorkingKey ( bool encrypting, byte key ) : int[]	Generates the working key.
ValidateKey ( ) : void	Validates the key.
