ECDiffieHellman Class
Provides an abstract base class that Elliptic Curve Diffie-Hellman (ECDH) algorithm implementations can derive from. This class provides the basic set of operations that all ECDH implementations must support.

Assembly: System.Core (in System.Core.dll)
The ECDiffieHellman type exposes the following members.
| Name | Description | |
|---|---|---|
 | KeyExchangeAlgorithm | Gets the name of the key exchange algorithm. (Overrides AsymmetricAlgorithm.KeyExchangeAlgorithm.) |
| KeySize | Gets or sets the size, in bits, of the key modulus used by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.) |
| LegalKeySizes | Gets the key sizes that are supported by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.) |
| PublicKey | Gets the public key that is being used by the current Elliptic Curve Diffie-Hellman (ECDH) instance. |
| SignatureAlgorithm | Gets the name of the signature algorithm. (Overrides AsymmetricAlgorithm.SignatureAlgorithm.) |
| Name | Description | |
|---|---|---|
 | Clear | Releases all resources used by the AsymmetricAlgorithm class. (Inherited from AsymmetricAlgorithm.) |
 | Create() | Creates a new instance of the default implementation of the Elliptic Curve Diffie-Hellman (ECDH) algorithm. |
| Create(String) | Creates a new instance of the specified implementation of the Elliptic Curve Diffie-Hellman (ECDH) algorithm. |
| DeriveKeyMaterial | Derives bytes that can be used as a key, given another party's public key. |
| Dispose() | Releases all resources used by the current instance of the AsymmetricAlgorithm class. (Inherited from AsymmetricAlgorithm.) |
 | Dispose(Boolean) | Releases the unmanaged resources used by the AsymmetricAlgorithm class and optionally releases the managed resources. (Inherited from AsymmetricAlgorithm.) |
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| FromXmlString | When overridden in a derived class, reconstructs an AsymmetricAlgorithm object from an XML string. (Inherited from AsymmetricAlgorithm.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| ToXmlString | When overridden in a derived class, creates and returns an XML string representation of the current AsymmetricAlgorithm object. (Inherited from AsymmetricAlgorithm.) |
| Name | Description | |
|---|---|---|
 | KeySizeValue | Represents the size, in bits, of the key modulus used by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.) |
| LegalKeySizesValue | Specifies the key sizes that are supported by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.) |
This class serves as the abstract base class for ECDH implementations.

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: MayLeakOnAbort. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes. |
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
