        }
        System.out.println();

        return pfx;
    }
}

当我使用此代码编写p12时，我尝试使用openssl或钥匙串将其打开，并提示我输入密码。我用他们的密码

public static char[] KEY_PASSWD = "keyPassword".toCharArray();

尝试打开P12，但是它不起作用。此外，当我按原样运行此主要功能时，将执行此行

System.err.println("PKCS#12 MAC test failed!");

为了正确地在p12上输入密码，他们的示例有问题吗？我基本上是想做相当于

openssl pkcs12 -export -des3

如果有其他想法，也可以使用Bouncy Castle在Java中使用。

问题答案：

元：这是一种解决方法，不能解决所提出的Q问题，但需要格式化。

要创建PKCS12的简单方法， 只需KeyStore按照其javadoc中的说明 使用即可 ，它应该在您的IDE
或Oracle网站上提供。这是一个最小的示例，结合了javadoc中的代码。由于您的Q不会显示您
从 何处获取createCredentials数据，对于本示例，我只是从现有的JKS中读取；根据需要更改此设置。并使用更好的密码！ __

我将使用默认提供程序（SunJSSE）和BC提供程序进行演示。我在最终测试中发现了一个警告：BC需要在Oracle
Java上安装“无限强度策略”-至少到j8。据说这个“功能”终于在j9中被删除了，但是我还没有测试。即使TDES 强度
只有112，应该允许，它也可能将168的TDES密钥大小视为超过128 。

char[] pw = "password".toCharArray(); // dummy for test
boolean useBC = System.getProperty("useBC")!=null;
KeyStore jks = KeyStore.getInstance("JKS");
InputStream f1 = new FileInputStream ("old.jks"); jks.load(f1, pw); f1.close();
PrivateKey pkey = (PrivateKey)jks.getKey("mykey", pw);
Certificate[] chain = jks.getCertificateChain("mykey");

// only needed once, and not at all if pre-configured in java.security  
if(useBC) Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());

// then do something like this
KeyStore p12 = useBC? KeyStore.getInstance("PKCS12","BC"): KeyStore.getInstance("PKCS12");
p12.load(null); p12.setKeyEntry("mykey", pkey, pw, chain);
OutputStream f2 = new FileOutputStream ("new.p12"); p12.store(f2,pw); f2.close();
