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. 091 * 092 * 093 * @author <a href="mailto:Karl.Scheibelhofer@iaik.at"> Karl Scheibelhofer </a> 094 * @version 0.1 095 * @invariants 096 */ 097 public class SignCertificateRequest { 098 099 static PrintWriter output_; 100 101 static BufferedReader input_; 102 103 static { 104 try { 105 //output_ = new PrintWriter(new FileWriter("GetInfo_output.txt"), true); 106 output_ = new PrintWriter(System.out, true); 107 input_ = new BufferedReader(new InputStreamReader(System.in)); 108 } catch (Throwable thr) { 109 thr.printStackTrace(); 110 output_ = new PrintWriter(System.out, true); 111 input_ = new BufferedReader(new InputStreamReader(System.in)); 112 } 113 } 114 115 public static void main(String[] args) { 116 if (args.length != 4) { 117 printUsage(); 118 System.exit(1); 119 } 120 121 try { 122 123 Module pkcs11Module = Module.getInstance(args[0]); 124 pkcs11Module.initialize(null); 125 126 Token token = Util.selectToken(pkcs11Module, output_, input_); 127 if (token == null) { 128 output_.println("We have no token to proceed.
