Class CertPathValidator

public class CertPathValidator extends Object

A class for validating certification paths (also known as certificate chains).

This class uses a provider-based architecture. To create a CertPathValidator, call one of the static getInstance methods, passing in the algorithm name of the CertPathValidator desired and optionally the name of the provider desired.

Once a CertPathValidator object has been created, it can be used to validate certification paths by calling the validate method and passing it the CertPath to be validated and an algorithm-specific set of parameters. If successful, the result is returned in an object that implements the CertPathValidatorResult interface.

The getRevocationChecker() method allows an application to specify additional algorithm-specific parameters and options used by the CertPathValidator when checking the revocation status of certificates. Here is an example demonstrating how it is used with the PKIX algorithm:

 CertPathValidator cpv = CertPathValidator.getInstance("PKIX");
 PKIXRevocationChecker rc = (PKIXRevocationChecker)cpv.getRevocationChecker();
 rc.setOptions(EnumSet.of(Option.SOFT_FAIL));
 params.addCertPathChecker(rc);
 CertPathValidatorResult cpvr = cpv.validate(path, params);
 

Every implementation of the Java platform is required to support the following standard CertPathValidator algorithm:

• PKIX

This algorithm is described in the CertPathValidator section of the Java Security Standard Algorithm Names Specification. Consult the release documentation for your implementation to see if any other algorithms are supported.

Concurrent Access

The static methods of this class are guaranteed to be thread-safe. Multiple threads may concurrently invoke the static methods defined in this class with no ill effects.

However, this is not true for the non-static methods defined by this class. Unless otherwise documented by a specific provider, threads that need to access a single CertPathValidator instance concurrently should synchronize amongst themselves and provide the necessary locking. Multiple threads each manipulating a different CertPathValidator instance need not synchronize.
