示例1: Validate
/**
* Validates an attribute certificate with the given certificate path.
*
* <p>
* <code>params</code> must be an instance of
* <code>ExtendedPkixParameters</code>.
* </p><p>
* The target constraints in the <code>params</code> must be an
* <code>X509AttrCertStoreSelector</code> with at least the attribute
* certificate criterion set. Obey that also target informations may be
* necessary to correctly validate this attribute certificate.
* </p><p>
* The attribute certificate issuer must be added to the trusted attribute
* issuers with {@link ExtendedPkixParameters#setTrustedACIssuers(Set)}.
* </p>
* @param certPath The certificate path which belongs to the attribute
* certificate issuer public key certificate.
* @param params The PKIX parameters.
* @return A <code>PKIXCertPathValidatorResult</code> of the result of
* validating the <code>certPath</code>.
* @throws InvalidAlgorithmParameterException if <code>params</code> is
* inappropriate for this validator.
* @throws CertPathValidatorException if the verification fails.
