我认为有两大问题
1. 通过 私钥 和 证书可以任意的产生 pfx，就算不是匹配的私钥和证书都可以产生pfx证书，我认为可能是私钥对证书进行了加密，此处可能涉及到 证书链的东西。
2. 在对 私钥的获取中，我采用的是 字符串的形式获取，直接读取字符串，然后进行了类型强转：通过字符串转成 字节数组，再通过PKCS8EncodeedKeySpec的方式 转换，最后通过KeyFactory的方法以RSA的形式获取，再产生 私钥。可能不妥。
09/25 又在网上找了个文章，看了一下，发现差不太多.原来：
2. 在进行 私钥转换时，也是采用 字符串 BASE64编码，然后 keyFactory转换成私钥。rsaPrivateKey也是使用PKCS8的标准。后来看了下， pkcs8 是私钥的标准。
1. 至于使用到了 chain，
X509Certificate[] chain = { x509Certificate }; 考虑可能是证书的一种表示形式，通过序列的形式表示出来。然后使用keyStore将 证书 和 私钥 合并起来，形成pfx。
对上面的程序进行了改进，就是排排版，看起来更顺眼一些。v2.0
