ECDiffieHellmanCng(ECCurve)

Source:
Cng.NotSupported.cs
Source:
Cng.NotSupported.cs
Source:
Cng.NotSupported.cs

Creates a new instance of the ECDiffieHellmanCng class whose public/private key pair is generated over the specified curve.

public:
 ECDiffieHellmanCng(System::Security::Cryptography::ECCurve curve);
public ECDiffieHellmanCng (System.Security.Cryptography.ECCurve curve);
