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

public class CreditCardTokenParameters : SecurityTokenParameters

    public CreditCardTokenParameters()

    }

    protected CreditCardTokenParameters(CreditCardTokenParameters other)

    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

Remarks

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.
