X509SubjectKeyIdentifierClause Class

Represents a key identifier clause that identifies a X509SecurityToken security token using the X.509 certificate's subject key identifier extension.

Namespace:  System.IdentityModel.Tokens
Assembly:  System.IdentityModel (in System.IdentityModel.dll)
public class X509SubjectKeyIdentifierClause : BinaryKeyIdentifierClause

The X509SubjectKeyIdentifierClause type exposes the following members.

  NameDescription
Public methodX509SubjectKeyIdentifierClauseInitializes a new instance of the X509SubjectKeyIdentifierClause class using the specified subject key identifier.

  NameDescription
Public propertyCanCreateKeyGets a value that indicates whether a key can be created. (Inherited from SecurityKeyIdentifierClause.)
Public propertyClauseTypeGets the key identifier clause type. (Inherited from SecurityKeyIdentifierClause.)
Public propertyDerivationLengthGets the size of the derived key. (Inherited from SecurityKeyIdentifierClause.)
Public propertyIdGets or sets the key identifier clause ID. (Inherited from SecurityKeyIdentifierClause.)

  NameDescription
Public methodStatic memberCanCreateFromGets a value that indicates whether a key identifier clause can be created for the specified X.509 certificate.
Public methodCreateKeyCreates a key based on the parameters passed into the constructor. (Inherited from SecurityKeyIdentifierClause.)
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 methodGetBufferGets the binary data that represents the key identifier. (Inherited from BinaryKeyIdentifierClause.)
Public methodGetDerivationNonceGets the nonce that was used to generate the derived key. (Inherited from SecurityKeyIdentifierClause.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Protected methodGetRawBufferGets the binary data that represents the key identifier. (Inherited from BinaryKeyIdentifierClause.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetX509SubjectKeyIdentifierGets the subject key identifier.
Public methodMatches(Byte[])Returns a value that indicates whether the binary data for the current instance matches the specified binary data. (Inherited from BinaryKeyIdentifierClause.)
Public methodMatches(SecurityKeyIdentifierClause)Returns a value that indicates whether the key identifier for this instance is equivalent to the specified key identifier clause. (Inherited from BinaryKeyIdentifierClause.)
Public methodMatches(X509Certificate2)Returns a value that indicates whether the key identifier for this instance is equivalent to the key identifier of the specified X.509 certificate.
Public methodMatches(Byte[], Int32)Returns a value that indicates whether the binary data for the current instance is equivalent to the specified binary data at the specified offset. (Inherited from BinaryKeyIdentifierClause.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Overrides Object.ToString().)
Public methodStatic memberTryCreateFromCreates a key identifier clause using the specified X.509 certificate.

Typically, the X509SubjectKeyIdentifierClause does not need to be used, other than when a custom security token service is created. When a security token service returns a security token, the issued security token contains references to attached and unattached security tokens. Attached references refer to security tokens that are contained within the security header of a SOAP message and unattached references are security tokens that are not included within the security header of a SOAP message. These references typically affirm the authenticity of the issued security token. Use the X509ThumbprintKeyIdentifierClause class to reference a X509SecurityToken security token using the X.509 certificate's subject key identifier extension. The GetX509SubjectKeyIdentifier method returns the subject key identifier extension.

Windows Communication Foundation (WCF) supports the following types of security token references for X509SecurityToken security tokens.
