public class PEPClientKeySelector
extends KeySelector

Implements the KeySelector interface for the DOMValidateContext in the method PEPClient.validateSignature(InputStream). Currently, this implementation supports only validation of X509Certificates as KeyInfo Content objects.

                          throws NoSuchAlgorithmException,
                                 CertificateException,

                                 CertPathBuilderException
Validates an X509Certificate. The validation comprises a validity check and the certification path. The validation takes places according to the default PKIX validation process. It uses the default (SSL)trust store defined in the system properties "javax.net.ssl.trustStore" and "javax.net.ssl.trustStorePassword".

Parameters:
cert - The X509Certificate to validate.
Throws:
NoSuchAlgorithmException
CertificateException
IOException
KeyStoreException
CertPathValidatorException
InvalidAlgorithmParameterException
CertPathBuilderException
