    075     * Signs a PKCS#10 certificate request using a token. The actual PKCS#10
    076     * specific operations are in the last section of this demo.
    077     * The hash is calculated outside the token. This implementation just uses raw
    078     * RSA.
    079     * This example works as follows. In general, the
    080     * <code>CertificateRequest</code> class from the IAIK JCE toolkit works with
    081     * JCA private keys only. To get it to work with the wrapper, we need a special
    082     * <code>AlgorithmID</code> class (see {@link demo.pkcs.pkcs11.AlgorithmIDAdapter })
    083     * which provides a special <code>Signature</code> engine object
    084     * (see {@link demo.pkcs.pkcs11.PKCS11SignatureEngine }) to the certificate
    085     * request object. This signature engine only accepts keys of type
    086     * {@link demo.pkcs.pkcs11.TokenPrivateKey }, which just wraps PKCS#11 key
    087     * objects. All these helper classes are required if you want to sign a
    088     * certificate request with the PKCS#11 wrapper. If you use the IAIK PKCS#11
    089     * provider, everything is much easier. In this case, you do not need any
    090     * of these helper classes.
