Authenticates a security token.
Assembly: System.IdentityModel (in System.IdentityModel.dll)
Thetype exposes the following members.
|CanValidateToken||Gets a value indicating whether the specified security token can be validated by this security token authenticator.|
|CanValidateTokenCore||When overridden in a derived class, gets a value indicating whether the specified security token can be validated by this security token authenticator.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|ValidateToken||Authenticates the specified security token and returns the set of authorization policies for the security token.|
|ValidateTokenCore||When overridden in a derived class, authenticates the specified security token and returns the set of authorization policies for the security token.|
The class and the classes that derive from it authenticate security tokens. Typically, you would only derive a class directly from when you create a custom security token. If you wanted to override the default authentication or authorization behaviors for built-in security tokens, derive from one of the classes that derive from , such as SamlSecurityTokenAuthenticator.
When you derive a class from , override the following two methods: ValidateTokenCore and CanValidateTokenCore. The CanValidateTokenCore method determines whether this security token authenticator can authenticate a specific security token. The ValidateTokenCore method authenticates the security token and establishes a set of authorization policies for authorization. The authorization policies map the claims found in the security token to claims required by the application.
