 *            {@link CertificateService.newX509Certificate} and made available
 *            as a property of the returned {@link X509Certificate} object.
 * @property {boolean} digitalSignature <code>true</code> if the
 *           <code>digital signature</code> flag is set, <code>false</code>
 *           otherwise.
 * @property {boolean} nonRepudiation <code>true</code> if the
 *           <code>non-repudiation</code> flag is set, <code>false</code>
 *           otherwise.
 * @property {boolean} keyEncipherment <code>true</code> if the
 *           <code>key encipherment</code> flag is set, <code>false</code>
 *           otherwise.
 * @property {boolean} dataEncipherment <code>true</code> if the
 *           <code>data encipherment</code> flag is set, <code>false</code>
 *           otherwise.
 * @property {boolean} keyAgreement <code>true</code> if the
