Examples of java.security.cert.Certificate.verify()

java.security.cert.Certificate.verify()
Verifies that this certificate was signed using the private key that corresponds to the specified public key. @param key the PublicKey used to carry out the verification. @exception NoSuchAlgorithmException on unsupported signaturealgorithms. @exception InvalidKeyException on incorrect key. @exception NoSuchProviderException if there's no default provider. @exception SignatureException on signature errors. @exception CertificateException on encoding errors.
