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.

Namespace:  System.Security.Cryptography
Assembly:  System.Core (in System.Core.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]
public abstract class ECDiffieHellman : AsymmetricAlgorithm

The ECDiffieHellman type exposes the following members.

  NameDescription
Protected methodECDiffieHellmanInitializes a new instance of the ECDiffieHellman class.
Top

  NameDescription
Public propertyKeyExchangeAlgorithmGets the name of the key exchange algorithm. (Overrides AsymmetricAlgorithm.KeyExchangeAlgorithm.)
Public propertyKeySizeGets or sets the size, in bits, of the key modulus used by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.)
Public propertyLegalKeySizesGets the key sizes that are supported by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.)
Public propertyPublicKeyGets the public key that is being used by the current Elliptic Curve Diffie-Hellman (ECDH) instance.
Public propertySignatureAlgorithmGets the name of the signature algorithm. (Overrides AsymmetricAlgorithm.SignatureAlgorithm.)
Top

  NameDescription
Public methodClearReleases all resources used by the AsymmetricAlgorithm class. (Inherited from AsymmetricAlgorithm.)
Public methodStatic memberCreate()Creates a new instance of the default implementation of the Elliptic Curve Diffie-Hellman (ECDH) algorithm.
Public methodStatic memberCreate(String)Creates a new instance of the specified implementation of the Elliptic Curve Diffie-Hellman (ECDH) algorithm.
Public methodDeriveKeyMaterialDerives bytes that can be used as a key, given another party's public key.
Public methodDispose()Releases all resources used by the current instance of the AsymmetricAlgorithm class. (Inherited from AsymmetricAlgorithm.)
Protected methodDispose(Boolean)Releases the unmanaged resources used by the AsymmetricAlgorithm class and optionally releases the managed resources. (Inherited from AsymmetricAlgorithm.)
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodFromXmlStringWhen overridden in a derived class, reconstructs an AsymmetricAlgorithm object from an XML string. Otherwise, throws a NotImplementedException. (Inherited from AsymmetricAlgorithm.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodToXmlStringWhen overridden in a derived class, creates and returns an XML string representation of the current AsymmetricAlgorithm object. Otherwise, throws a NotImplementedException. (Inherited from AsymmetricAlgorithm.)

  NameDescription
Protected fieldKeySizeValueRepresents the size, in bits, of the key modulus used by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.)
Protected fieldLegalKeySizesValueSpecifies the key sizes that are supported by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.)

This class serves as the abstract base class for ECDH implementations.

NoteNote

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.
