将证书链保存在pkcs12密钥库中

Question

以下代码:

//used Bouncy Castle provider for keyStore
keyStore.setKeyEntry(alias, (Key)keyPair.getPrivate(), pwd, certChain);  

certChain持有结束证书和颁发者证书(即两个证书)
的情况下,如果keyStore是一个实例,则不会将发行者证书保存为保存到文件系统密钥库文件中的链的一部分PKCS12.

如果密钥库类型是,它确实保存两个证书PKCS12-3DES-3DES.为什么是这样？PKCS12是否假设两个证书都是链的一部分？

编辑:这是一个SSCCE.这很好用"JKS",失败的原因是"PKCS12":只有链中的第一个证书可以访问getCertificateChain(String).可以打开保存的文件,同时openssl pkcs12显示两个证书.

    public void testKeyStore() {
    try {
        KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");
        keyPairGenerator.initialize(1024);
        KeyPair keyPair = keyPairGenerator.generateKeyPair();
        PublicKey publicKey = keyPair.getPublic();
        PrivateKey privateKey = keyPair.getPrivate();
        Certificate[] outChain = { createCertificate("CN=CA", publicKey, privateKey), createCertificate("CN=Client", publicKey, privateKey) };

        KeyStore outStore = KeyStore.getInstance("PKCS12");
        outStore.load(null, "secret".toCharArray());
        outStore.setKeyEntry("mykey", privateKey, "secret".toCharArray(), outChain);            
        OutputStream outputStream = new FileOutputStream("c:/outstore.pkcs12");
        outStore.store(outputStream, "secret".toCharArray());
        outputStream.flush();
        outputStream.close();

        KeyStore inStore = KeyStore.getInstance("PKCS12");      
        inStore.load(new FileInputStream("c:/outstore.pkcs12"), "secret".toCharArray());
        Key key = outStore.getKey("myKey", "secret".toCharArray());
        assertEquals(privateKey, key);

        Certificate[] inChain = outStore.getCertificateChain("mykey");
        assertNotNull(inChain);
        assertEquals(outChain.length, inChain.length);
    } catch (Exception e) {
        e.printStackTrace();
        fail(e.getMessage());
    }
}

private static X509Certificate createCertificate(String dn, PublicKey publicKey, PrivateKey privateKey) throws Exception {
    X509V3CertificateGenerator certGenerator = new X509V3CertificateGenerator();
    certGenerator.setSerialNumber(new BigInteger("1"));
    certGenerator.setIssuerDN(new X509Name(dn));
    certGenerator.setSubjectDN(new X509Name(dn));
    certGenerator.setNotBefore(Calendar.getInstance().getTime());
    certGenerator.setNotAfter(Calendar.getInstance().getTime());
    certGenerator.setPublicKey(publicKey);
    certGenerator.setSignatureAlgorithm("SHA1withRSA");
    X509Certificate certificate = (X509Certificate)certGenerator.generate(privateKey, "BC");
    return certificate;
}

您的代码有2个错误:

第一:您没有为证书设置Issuer(客户证书应由CA颁发以生成有效链).

第二:创建证书链时使用错误的顺序(应该是客户端ferts,CA last)

这里是重写的SSCCE,它没有错误.

根据您使用的 JDK，有不同的方法来打包您的应用程序。当一些人使用 Linux 和 OpenJDK，而另一些人使用 SunJDK (Oracle) 在 Windows 上进行开发时，这种情况就会发生在我们身上。

最新的需要进行一些额外的配置才能使用最强大的算法。如果您的问题与 JCE 策略相关，本文可以为您提供帮助。
