ECDiffieHellmanOpenSsl(Int32)

Initializes a new instance of the ECDiffieHellmanOpenSsl class defaulting to the NIST prime curve of the specified size.

ECDiffieHellmanOpenSsl(IntPtr)

Initializes a new instance of the ECDiffieHellmanOpenSsl class from an existing OpenSSL key represented as an EC_KEY*.

ECDiffieHellmanOpenSsl(ECCurve)

Initializes a new instance of the ECDiffieHellmanOpenSsl class and generates a new key on the specified curve.

ECDiffieHellmanOpenSsl()

Source:
ECDiffieHellmanOpenSsl.cs
Source:
ECDiffieHellmanOpenSsl.cs
Source:
ECDiffieHellmanOpenSsl.cs

Initializes a new instance of the ECDiffieHellmanOpenSsl class with a default curve of NIST P-521/secp521r1.

public:
 ECDiffieHellmanOpenSsl();
public ECDiffieHellmanOpenSsl ();
[System.Runtime.Versioning.UnsupportedOSPlatform("android")]

[System.Runtime.Versioning.UnsupportedOSPlatform("windows")]
public ECDiffieHellmanOpenSsl ();
Public Sub New ()
Attributes

Remarks

This constructor does not generate a new public/private keypair immediately, it just sets the size which will be used to generate a key when one is needed. If key is loaded via the ImportParameters method, or other key import method, the key size from this constructor has no meaning.

ECDiffieHellmanOpenSsl(Int32)

Source:
ECDiffieHellmanOpenSsl.cs

ECDiffieHellmanOpenSsl.cs

Initializes a new instance of the ECDiffieHellmanOpenSsl class defaulting to the NIST prime curve of the specified size.

public:

new System.Security.Cryptography.ECDiffieHellmanOpenSsl : int -> System.Security.Cryptography.ECDiffieHellmanOpenSsl
Public Sub New (keySize As Integer)

Parameters

keySize
Int32

The size of the key to generate, when a key is needed.

Attributes

Exceptions

The keySize value is not supported by this implementation.

Remarks

Only three key sizes are supported by this constructor: 256 (NIST P-256/secp256r1), 384 (NIST P-384/secp384r1), and 521 (NIST P-521/secp521r1). To generate keys For any other curve, use the ECDiffieHellmanOpenSsl(ECCurve) constructor or the GenerateKey(ECCurve) method.

This constructor does not generate a new public/private keypair immediately, it just sets the size which will be used to generate a key when one is needed. If key is loaded via the ImportParameters method, or other key import method, the key size from this constructor has no meaning.
