Class SAMLProtocolMessageXMLSignatureSecurityHandler

All Implemented Interfaces:
Component, DestructableComponent, InitializableComponent, MessageHandler

public class SAMLProtocolMessageXMLSignatureSecurityHandler extends BaseSAMLXMLSignatureSecurityHandler
SAML security message handler which validates the signature (if present) on the SAMLObject which represents the SAML protocol message being processed.

If the message is not an instance of SignableSAMLObject, then no processing is performed. If signature validation is successful, and the SAML message context issuer was not previously authenticated, then the context's authentication state will be set to true.

If an optional SAMLSignatureProfileValidator or subclass is supplied, this validator will be used to validate the XML Signature element prior to the actual cryptographic validation of the signature. This might for example be used to enforce certain signature profile requirements or to detect signatures upon which it would be unsafe to attempt cryptographic processing. The validator will default to SAMLSignatureProfileValidator.

      @Nullable public SignaturePrevalidator getSignaturePrevalidator()
      Get the prevalidator for XML Signature instances.
      Returns the prevalidator.

    • doInvoke

      public void doInvoke(@Nonnull MessageContext messageContext) throws MessageHandlerException
      Performs the handler logic.
      Specified by:
      doInvoke in class AbstractMessageHandler
      messageContext - the message context on which to invoke the handler
      MessageHandlerException - if there is an error invoking the handler on the message context
    • doEvaluate

      protected void doEvaluate(@Nonnull Signature signature, @Nonnull SignableSAMLObject signableObject, @Nonnull MessageContext messageContext) throws MessageHandlerException
      Perform cryptographic validation and trust evaluation on the Signature token using the configured Signature trust engine.
      signature - the signature which is being evaluated
      signableObject - the signable object which contained the signature
      messageContext - the SAML message context being processed
      MessageHandlerException - thrown if the signature fails validation
    • performPrevalidation

      protected void performPrevalidation(@Nonnull Signature signature) throws MessageHandlerException
      Perform pre-validation on the Signature token.
      signature - the signature to evaluate
      MessageHandlerException - thrown if the signature element fails pre-validation
