NSData到Java字符串 [英] NSData to Java String

问题描述

我最近一直在写一个Web应用程序与iPhone进行交互。 iPhone iphone实际上将以plist的形式发送信息到服务器。因此，看到类似的东西并不少见...

I've been writing a Web Application recently that interacts with iPhones. The iPhone iphone will actually send information to the server in the form of a plist. So it's not uncommon to see something like...

<key>RandomData</key>
<data>UW31vrxbUTl07PaDRDEln3EWTLojFFmsm7YuRAscirI=</data>

现在我知道这些数据是以某种方式散列/加密的。当我用编辑器（属性列表编辑器）打开plist时，它显示了一个更加可读的格式。例如，上面的数据将被转换成类似...的内容。

Now I know this data is hashed/encrypted in some fashion. When I open up the plist with an editor (Property List Editor), it shows me a more "human readable" format. For example, the data above would be converted into something like...

任何想法转换的方法是什么？

Any idea what the method of converting it is? Mainly I'm looking to get this into a Java String.

谢谢！

推荐答案

在base64解码后，你需要对它进行十六进制编码。这是PL编辑器向你展示的。

After base64 decoding it you need to hex encode it. This is what PL Editor is showing you.

所以...

<key>SomeData</key>
<data>UW31ejxbelle7PaeRAEen3EWMLojbFmsm7LuRAscirI=</data?

可以用...表示

byte[] bytes = Base64.decode("UW31ejxbelle7PaeRAEen3EWMLojbFmsm7LuRAscirI=");
BigInteger bigInt = new BigInteger(bytes);
String hexString = bigInt.toString(16);
System.out.println(hexString);

获取...
