Méthodes publiques

Méthode	Description
CreateKeyExchange ( ) : byte[]	Creates the key exchange data.
DecryptKeyExchange ( byte keyEx ) : byte[]	Extracts secret information from the key exchange data.
DiffieHellmanManaged ( ) : System	Initializes a new DiffieHellmanManaged instance. The default length of the shared secret is 1024 bits.
DiffieHellmanManaged ( byte p, byte g, byte x ) : System	Initializes a new DiffieHellmanManaged instance.
DiffieHellmanManaged ( byte p, byte g, int l ) : System	Initializes a new DiffieHellmanManaged instance.
DiffieHellmanManaged ( int bitlen, int l, DHKeyGeneration keygen ) : System	Initializes a new DiffieHellmanManaged instance. The larger the bit length, the more secure the algorithm is. The default is 1024 bits. The minimum bit length is 128 bits. The size of the private value will be one fourth of the bit length specified.
ExportParameters ( bool includePrivateParameters ) : DHParameters	Exports the DHParameters.
ImportParameters ( DHParameters parameters ) : void	Imports the specified DHParameters.

Méthodes protégées

Méthode	Description
Dispose ( bool disposing ) : void	Releases the unmanaged resources used by the SymmetricAlgorithm and optionally releases the managed resources.

Method Details

CreateKeyExchange() public méthode

Creates the key exchange data.

public CreateKeyExchange ( ) : byte[]
Résultat	byte[]

DecryptKeyExchange() public méthode

Extracts secret information from the key exchange data.

public DecryptKeyExchange ( byte keyEx ) : byte[]
keyEx	byte	The key exchange data within which the shared key is hidden.
Résultat	byte[]

DiffieHellmanManaged() public méthode

Initializes a new DiffieHellmanManaged instance.

The default length of the shared secret is 1024 bits.

public DiffieHellmanManaged ( ) : System
Résultat	System

DiffieHellmanManaged() public méthode

Initializes a new DiffieHellmanManaged instance.

or is a null reference (Nothing in Visual Basic). or is invalid.

public DiffieHellmanManaged ( byte p, byte g, byte x ) : System
p	byte	The P parameter of the Diffie-Hellman algorithm. This is a public parameter.
g	byte	The G parameter of the Diffie-Hellman algorithm. This is a public parameter.
x	byte	The X parameter of the Diffie-Hellman algorithm. This is a private parameter. If this parameters is a null reference (Nothing in Visual Basic), a secret value of the default size will be generated.
Résultat	System

p	byte	The P parameter of the Diffie-Hellman algorithm.
g	byte	The G parameter of the Diffie-Hellman algorithm.
l	int	The length, in bits, of the private value. If 0 is specified, the default value will be used.
Résultat	System

DiffieHellmanManaged() public méthode

Initializes a new DiffieHellmanManaged instance.

The larger the bit length, the more secure the algorithm is. The default is 1024 bits. The minimum bit length is 128 bits.
The size of the private value will be one fourth of the bit length specified.

The specified bit length is invalid.

public DiffieHellmanManaged ( int bitlen, int l, DHKeyGeneration keygen ) : System
bitlen	int	The length, in bits, of the public P parameter.
l	int	The length, in bits, of the secret value X. This parameter can be set to 0 to use the default size.
keygen	DHKeyGeneration	One of the values.
Résultat	System

Dispose() protected méthode
