/**
 * This method creates an X509v3 certificate based on an an existing certificate.
 * It attempts to create as faithful a copy of the existing certificate as possible
 * by duplicating all certificate extensions.
 *
 * If you are testing an application that makes use of additional certificate
 * extensions (e.g. logotype, S/MIME capabilities) this method will preserve those
 * fields./*from   w  ww  .  j a va 2s  . c  o m*/
 *
 * You may optionally include a set of OIDs not to copy from the original certificate.
 * The most common reason to do this would be to remove fields that would cause inconsistency,
 * such as Authority Info Access or Issuer Alternative Name where these are not defined for
 * the MITM authority certificate.
 *
 * OIDs 2.5.29.14 : Subject Key Identifier and 2.5.29.35 : Authority Key Identifier,
 * are never copied, but generated directly based on the input keys and certificates.
 *
 * You may also optionally include maps of custom extensions which will be added to or replace
 * extensions with the same OID on the original certificate for the the MITM certificate.
 *
 * FUTURE WORK: JDK 1.5 is very strict in parsing extensions.  In particular, known extensions
 * that include URIs must parse to valid URIs (including URL encoding all non-valid URI characters)
 * or the extension will be rejected and not available to copy to the MITM certificate.  Will need
 * to directly extract these as ASN.1 fields and re-insert (hopefully BouncyCastle will handle them)
 *
 *
 * @param originalCert  The original certificate to duplicate.
 * @param newPubKey     The new public key for the MITM certificate.
 * @param caCert        The certificate of the signing authority fot the MITM certificate.
 * @param caPrivateKey  The private key of the signing authority.
 * @param extensionOidsNotToCopy  An optional list of certificate extension OIDs not to copy to the MITM certificate.
