在JAVA中使用PKCS11创建PKCS10证书请求

标签: java cryptography provider pkcs#11

我必须为存储在cryptocard上的RSA密钥对创建PKCS10证书请求,并通过PKCS11接口进行访问。问题是我不能在PKCS10创建过程中使用标准的RSA算法而且我无法从密码卡中获取私钥,因此应该在密码卡方面进行加密操作。如何使用PKCS11接口准备(可能手动)PKCS10请求进行签名?

@Edit 现在我有这样的错误:

Exception in thread "main" java.security.ProviderException: Initialization failed

和代码:

    String zawartoscPlikuKonfiguracyjnego = new String(
            "name=PKCS11\n" +
            "library=" + sciezkaDoBibliotekiPkcs11);

    FileOutputStream plikKonfiguracyjny = new FileOutputStream("pkcs11.cfg");
    plikKonfiguracyjny.write(zawartoscPlikuKonfiguracyjnego.getBytes());
    plikKonfiguracyjny.close();

    File test = new File("pkcs11.cfg");
    dostawcaPkcs11 = new SunPKCS11("pkcs11.cfg");
    Security.addProvider(dostawcaPkcs11);

    interfejsPkcs11 = KeyStore.getInstance("PKCS11",dostawcaPkcs11);        
    pin = new JPasswordField();
    JOptionPane.showConfirmDialog(null, pin, "Podaj pin do tokena", JOptionPane.OK_CANCEL_OPTION);

    interfejsPkcs11.load(null, pin.getPassword());

    Key kluczPrywatny = null;
    Key kluczPubliczny = null;

    Enumeration<String> aliasy = interfejsPkcs11.aliases();
    while(aliasy.hasMoreElements()) {
        String alias = aliasy.nextElement();
        if(interfejsPkcs11.isKeyEntry(alias)) {
            kluczPrywatny = interfejsPkcs11.getKey(alias, pin.getPassword());
        } else {
            kluczPubliczny = interfejsPkcs11.getCertificate(alias).getPublicKey();
        }
    }

    PKCS10 pkcs10 = new PKCS10((PublicKey) kluczPubliczny );
    Signature sygnatura = Signature.getInstance("SHA1WithRSA", dostawcaPkcs11);
    sygnatura.initSign((PrivateKey) kluczPrywatny);
    X500Name nazwaX500 = new X500Name("Certyfikat testowy", "Developer", "Developer", "Warszawa", "Mazovia", "PL");
    pkcs10.encodeAndSign(nazwaX500, sygnatura);

我建议您尝试使用Sun PKCS#11提供程序。您需要按照the documentation了解如何配置提供程序以使用您的cryptocard供应商提供的DLL。 (另外值得向他们询问他们推荐的从Java访问密码卡的方法)。

一旦你有了这个工作,你应该能够从密钥库加载你的公钥和私钥(再次参见文档,了解它的工作原理)。最后,您可以使用JCE库来生成签名请求:

String CN = "Mr Foo";
String OU = "Foo Department";
String O = "Foo Ltd.";
String L = "Foosville";
String S = "Foouisiana";
String C = "GB";

PublicKey publicKey = //... load public key from keystore
PrivateKey privateKey = //... load private key from keystore

PKCS10 pkcs10 = new PKCS10(publicKey);
Signature signature = Signature.getInstance("SHA1WithRSA"); // or whatever
signature.initSign(privateKey);    
X500Name x500Name = new X500Name(CN, OU, O, L, S, C);
pkcs10.encodeAndSign(new X500Signer(signature, x500Name));

try (ByteArrayOutputStream bs = new ByteArrayOutputStream(); 
     PrintStream ps = new PrintStream(bs)) {
  pkcs10.print(ps);
  byte[] c = bs.toByteArray(); // <-- this is it! (save to disk maybe?)
}
