   ↳ java.security.cert.CertPathValidator

Class Overview

This class provides the functionality for validating certification paths (certificate chains) establishing a trust chain from a certificate to a trust anchor.

Throws
NoSuchAlgorithmException if no installed provider provides the specified algorithm.
NullPointerException if algorithm is null.

public final Provider getProvider ()

Since: API Level 1

Returns the security provider.

Returns
  • the provider.

public final CertPathValidatorResult validate (CertPath certPath, CertPathParameters params)
