Another TokenValidator implementation that ships with the STS is the X509TokenValidator. This class validates an X.509 V.3 certificate (received as a BinarySecurityToken). The BinarySecurityToken must use Base-64 encoding. The received cert must be known (or trusted) by the STS crypto object, that is set on the STSPropertiesMBean object. The X509TokenValidator has a single property that can be configured:

  • void setValidator(Validator validator) - Set the WSS4J Validator instance to use to validate the received certificate. The default is SignatureTrustValidator.

No proof-of-possession is done with the received certificate. The subject principal of the certificate is set on the response, if validation is successful. Note that no caching is used in this TokenValidator implementation.
