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.
