SecurityTokenParameters Class

Specifies an abstract class that when implemented represents security token parameters.

Namespace:  System.ServiceModel.Security.Tokens
Assemblies:   System.ServiceModel.Security (in System.ServiceModel.Security.dll)
  System.ServiceModel (in System.ServiceModel.dll)

public abstract class SecurityTokenParameters

The SecurityTokenParameters type exposes the following members.

  NameDescription
Protected methodSecurityTokenParameters()Initializes a new instance of the SecurityTokenParameters class.
Protected methodSecurityTokenParameters(SecurityTokenParameters)Initializes a new instance of the SecurityTokenParameters class from another instance.

  NameDescription
Protected propertyHasAsymmetricKeyWhen overridden in a derived class, gets a value that indicates whether the token has an asymmetric key.
Public propertyInclusionModeGets or sets the token inclusion requirements.
Public propertyReferenceStyleGets or sets the token reference style.
Public propertyRequireDerivedKeysGets or sets a value that indicates whether keys can be derived from the original proof keys.
Protected propertySupportsClientAuthenticationWhen overridden in a derived class, gets a value that indicates whether the token supports client authentication.
Protected propertySupportsClientWindowsIdentityWhen overridden in a derived class, gets a value that indicates whether the token supports a Windows identity for authentication.
Protected propertySupportsServerAuthenticationWhen overridden in a derived class, gets a value that indicates whether the token supports server authentication.

Security token parameters provide information about the tokens (for example, token type, issuer, and so on) required by the security binding element.

The security token parameter classes derived from this one are a collection of token properties and methods, and are used in creating different kinds of security binding elements and tokens. Not all of the properties are relevant to all derived classes. For example, the ReferenceStyle has no relevance in an issued token (SAML token) case.

The following code shows a custom override of this class called CreditCardTokenParameters.

public class CreditCardTokenParameters : SecurityTokenParameters
{
    public CreditCardTokenParameters()
    {
    }

    protected CreditCardTokenParameters(CreditCardTokenParameters other)
        : base(other)
    {
    }

    protected override SecurityTokenParameters CloneCore()
    {
        return new CreditCardTokenParameters(this);
    }

    protected override void InitializeSecurityTokenRequirement(SecurityTokenRequirement requirement)
    {
        requirement.TokenType = Constants.CreditCardTokenType;
        return;
    }

    // A credit card token has no cryptography, no windows identity, and supports only client authentication. 
    protected override bool HasAsymmetricKey 
    { 
        get { return false; } 
    }

    protected override bool SupportsClientAuthentication 
    { 
        get { return true; } 
    }

    protected override bool SupportsClientWindowsIdentity 
    { 
        get { return false; } 
    }

    protected override bool SupportsServerAuthentication 
    { 
        get { return false; } 
    }

    protected override SecurityKeyIdentifierClause CreateKeyIdentifierClause(SecurityToken token, SecurityTokenReferenceStyle referenceStyle)
    {
        if (referenceStyle == SecurityTokenReferenceStyle.Internal)
        {
            return token.CreateKeyIdentifierClause<LocalIdKeyIdentifierClause>();
        }
        else
        {
            throw new NotSupportedException("External references are not supported for credit card tokens");
        }
    }
}
