For topics dealing with general Windows Communication Foundation (WCF) security-related topics, for example, SecurityAlgorithmSuite. see System.ServiceModel.Security.

For security topics that overlap with the service model, for example TcpTransportSecurity, see System.ServiceModel.

 Classes

	Class	Description
	BinarySecretSecurityToken	Represents a binary secret security token.
	ClaimTypeRequirement	Specifies the types of required and optional claims expected to appear in the federated credential.
	InitiatorServiceModelSecurityTokenRequirement	Specifies security property requirements specific to channel creation in the Windows Communication Foundation (WCF).
	IssuedSecurityTokenParameters	Represents the parameters for a security token issued in a Federated security scenario.
	IssuedSecurityTokenProvider	Token provider for issued security tokens.
	KerberosSecurityTokenParameters	Represents the parameters for a Kerberos security token.
	RecipientServiceModelSecurityTokenRequirement	Specifies security property requirements specific to the listener service in the Windows Communication Foundation (WCF).
	RsaSecurityTokenParameters	Represents the parameters for an RSA security token.
	SecureConversationSecurityTokenParameters	Represents the parameters for a secure conversation security token.
	SecurityContextSecurityToken	Represents the token defined by the WS-SecureConversation specification.
	SecurityContextSecurityTokenAuthenticator	Validates tokens and extracts claims.
	SecurityContextSecurityTokenResolver	Resolves security context tokens.
	SecurityTokenParameters	An abstract class that when implemented represents security token parameters.
	ServiceModelSecurityTokenRequirement	An abstract class that when implemented specifies security property requirements of the token being requested or authenticated that are specific to Windows Communication Foundation (WCF). The security token manager constructs security token providers and security token authenticators that are used by the WCF security processor based on the token requirement.
	ServiceModelSecurityTokenTypes	Represents the types of security tokens recognized by WCF.
	SslSecurityTokenParameters	Represents the parameters for an SSL security token that is obtained when doing the SOAP-level SSL protocol with the server.
	SspiSecurityToken	Represents an SSPI security token.
	SspiSecurityTokenParameters	Represents the parameters for an SSPI security token that is obtained during the SOAP-level SPNEGO protocol with the server.
	SupportingTokenParameters	Represents the parameters for supporting security tokens required by the security binding element.
	UserNameSecurityTokenParameters	Represents the parameters for a user name security token.
	WrappedKeySecurityToken	Represents a security token whose key is wrapped inside another token.
	X509SecurityTokenParameters	Represents the parameters for an X.509 security token.

 Interfaces

	Interface	Description
	IIssuanceSecurityTokenAuthenticator	Specifies the contract that should be implemented by a custom security token authenticator that issues tokens to the client.
	ILogonTokenCacheManager	This interface enables an application to clear the Windows token cache on demand.
	ISecurityContextSecurityTokenCache	When implemented, this interface specifies a contract for a security context token cache.

 Delegates

	Delegate	Description
	IssuedSecurityTokenHandler	This delegate points to a method that when implemented will be called by the Authenticators before the token is issued to the client.
	RenewedSecurityTokenHandler	The delegate when implemented is called before a renewed token is returned to the client.

 Enumerations

	Enumeration	Description
	SecurityTokenInclusionMode	A list of token inclusion requirements for messages.
	SecurityTokenReferenceStyle	This enumeration sets the desired referencing style that is used to generate security token references (STR) to the security tokens from the signature and encryption elements in the message.
	X509KeyIdentifierClauseType	An enumeration listing the possible types of X.509 key identifier clauses.
