加密/解密.plist文件ios [英] Encrypt/decrypt .plist file ios

问题描述

我有一个plist与一些存储的数据，并希望加密解密，所以它不可读使用目标c。我已经阅读了关于AES加密等等，但我希望整个plist被加密一些如何不是plist中的字符串....

任何帮助将非常感谢

解决方案

由howanghk提供的链接包含有错误的代码。在该网页上应用由InoriXu提供的修复以解决问题。您必须修改加密和解密功能。​​

所以在一行之后：

  const char * password = [pass UTF8String]; 
  

add：

 code> const int passwordLen = [pass length]; 
  

更改行：

  key [i] = password！= 0？ *密码++：0; 
  

into：

 code> key [i] = i< passwordLen！= 0？ *密码++：0; 
  

代码本身仍然添加了一些空格填充，但如果需要加密属性列表，你会很好。

i have a plist with some stored data and want to encrypt decrypt so it's not readable using objective c. i've read about AES encryption etc but i want the whole plist to be encrypted some how not the strings in the plist....

any help will be really appreciated.

解决方案

The link provided by howanghk contains code with a bug. Apply fix provided by InoriXu on that webpage to resolve the issue. You have to modify both encrypt and decrypt functions.

So after a line:

const char *password = [pass UTF8String];

add:

const int passwordLen = [pass length];

And change line:

key[i] = password != 0 ? *password++ : 0;

into:

key[i] = i < passwordLen != 0 ? *password++ : 0;

The code itself still adds some space padding behind, but if you need it to encrypt a property list, you'll be fine.
