' The credit card token is not capable of any cryptography. Throw New ArgumentNullException("cardInfo") Public Sub New(ByVal cardInfo As CreditCardInfo, _ Me.New(cardInfo, Guid.NewGuid().ToString()) Public Sub New(ByVal cardInfo As CreditCardInfo) Private _securityKeys As ReadOnl圜ollection(Of SecurityKey) Private _effectiveTime As DateTime = DateTime.UtcNow Public CreditCardToken(CreditCardInfo cardInfo) : this(cardInfo, Guid.NewGuid().ToString()) class CreditCardToken : SecurityTokenĭateTime effectiveTime = DateTime.UtcNow In this example, the credit card security token has only an expiration date, so the ValidFrom property returns a DateTime that represents the date and time of the instance creation. These properties are used by WCF to determine the validity of the security token instance. Override the ValidFrom and ValidTo properties. In this example, the credit card security token cannot contain any security keys therefore, the implementation always returns an empty collection. Such keys can be used by WCF to sign or encrypt parts of the SOAP message. This property returns a collection of security keys that the security token instance represents. In this example, a token identifier can be either passed to it as a constructor parameter or a new random one is generated every time a security token instance is created. This property is used to get the local identifier of the security token that is used to point to the security token XML representation from other elements inside the SOAP message. This example creates a class named CreditCardToken. To create a custom security token classĭefine a new class derived from the SecurityToken class. This class is used by the security token provider, authenticator, and serializer classes to pass information about the security token to and from the WCF security infrastructure. Next, a class that represents the custom security token must be created. Public ReadOnly Property ExpirationDate() As DateTime Public ReadOnly Property CardIssuer() As String Public ReadOnly Property CardNumber() As String Public Sub New(ByVal cardNumber As String, ByVal cardIssuer As String, _ Public CreditCardInfo(string cardNumber, string cardIssuer, DateTime expirationDate) In this example, the class has three properties: CardNumber, CardIssuer, and ExpirationDate. The following example names the class CreditCardInfo.Īdd appropriate properties to the class to allow an application set the necessary information required for the custom token. To create a class that represents credit card information inside client credentialsĭefine a new class that represents the credit card information for the application. The first step is to create a class to represent the credit card information for custom client credentials. This information is made available to the application by a custom client credentials class. ProceduresĪ client application must be provided with a way to specify credit card information for the security infrastructure. See the namespace for more classes that represent security tokens. This topic creates a credit card token that is used to pass information about the client's credit card to the server.įor more information about custom credentials and security token manager, see Walkthrough: Creating Custom Client and Service Credentials. The following procedures show how to create a custom security token and how to integrate it with the WCF security infrastructure. In that case, it is necessary to create a custom security token to provide an XML representation of the custom credential inside the SOAP message. Sometimes an authentication mode or credential is not supported by the provided types. Examples include an X.509 certificate security token represented by the X509SecurityToken class or a Username security token represented by the UserNameSecurityToken class. WCF security provides various tokens for system-provided authentication modes. For a complete code example see the Custom Token sample.Ī security token is essentially an XML element that is used by the Windows Communication Foundation (WCF) security framework to represent claims about a sender inside the SOAP message. This topic shows how to create a custom security token using the SecurityToken class, and how to integrate it with a custom security token provider and authenticator.
