Examples of sun.security.x509.X509CertImpl.sign()

sun.security.x509.X509CertImpl.sign()
Creates an X.509 certificate, and signs it using the given key (associating a signature algorithm and an X.500 name). This operation is used to implement the certificate generation functionality of a certificate authority. @param key the private key used for signing. @param algorithm the name of the signature algorithm used. @exception InvalidKeyException on incorrect key. @exception NoSuchAlgorithmException on unsupported signaturealgorithms. @exception NoSuchProviderException if there's no default provider. @exception SignatureException on signature errors. @exception CertificateException on encoding errors.
