void	configure(ConfigurationBean configuration)
org.opensaml.saml2.core.Assertion	getAssertionObject(String assertionString) Generates an assertion object from a string
org.opensaml.saml2.core.Assertion	validateAssertions(String xml) This method is invoked by the clients/stubs to validate the signature of assertions using the public key of the signed entity read from a file, returns null if signature is not valid

Description copied from interface: IAssertionValidator

This method is invoked by the clients/stubs to validate the signature of assertions using the public key of the signed entity read from a file, returns null if signature is not valid

Specified by:

validateAssertions in interface IAssertionValidator

Parameters:

xml - SAML assertion in String

Returns:

Assertion object if signature is valid or null if the signature is invalid

Throws:

AssertionValidationException - in case of any exceptions

org.opensaml.xml.ConfigurationException - if an invalid configuration has been inserted

getAssertionObject

public org.opensaml.saml2.core.Assertion getAssertionObject(String assertionString)

Description copied from interface: IAssertionValidator

Generates an assertion object from a string

Specified by:

getAssertionObject in interface IAssertionValidator

Returns:

an assertion object if the generation process has been correctly completed, null otherwise

validateTimeInterval

public boolean validateTimeInterval(org.opensaml.saml2.core.Assertion assertion)

Description copied from interface: IAssertionValidator

Validates the lifetime of the assertion basing on the notBefore and notOnOrAfter properties

Specified by:

validateTimeInterval in interface IAssertionValidator

Returns:

true if the validation is OK, false otherwise

validateSignature

public boolean validateSignature(org.opensaml.saml2.core.Assertion assertion)
                          throws org.opensaml.xml.ConfigurationException

Description copied from interface: IAssertionValidator

Validates the signature of the assertion

Specified by:

validateSignature in interface IAssertionValidator

Parameters:

assertion - the assertion

Returns:

true if the signature is valid, false otherwise

Throws:

org.opensaml.xml.ConfigurationException
