ECDiffieHellmanCngPublicKey Class

Specifies an Elliptic Curve Diffie-Hellman (ECDH) public key for use with the ECDiffieHellmanCng class.


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

[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]
public sealed class ECDiffieHellmanCngPublicKey : ECDiffieHellmanPublicKey

The ECDiffieHellmanCngPublicKey type exposes the following members.

Public propertyBlobFormatGets the key BLOB format for a ECDiffieHellmanCngPublicKey object.

Public methodDispose()Releases all resources used by the current instance of the ECDiffieHellman class. (Inherited from ECDiffieHellmanPublicKey.)
Protected methodDispose(Boolean)Releases the unmanaged resources used by the ECDiffieHellman class and optionally releases the managed resources. (Inherited from ECDiffieHellmanPublicKey.)
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 methodStatic memberFromByteArrayConverts a byte array that contains a public key to a ECDiffieHellmanCngPublicKey object according to the specified format.
Public methodStatic memberFromXmlStringConverts an XML string to an ECDiffieHellmanCngPublicKey object.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodImportConverts the ECDiffieHellmanCngPublicKey object to a CngKey object.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToByteArraySerializes the ECDiffieHellmanPublicKey key BLOB to a byte array. (Inherited from ECDiffieHellmanPublicKey.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodToXmlStringSerializes the ECDiffieHellmanCngPublicKey public key to an XML string in RFC 4050 format. (Overrides ECDiffieHellmanPublicKey.ToXmlString().)

ECDiffieHellmanCngPublicKey objects are used in key exchanges with ECDiffieHellmanCng objects.


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.
