新人急请IPA高手指导，关于info.plist那些事

麻烦您能给我一段加密的字符串吗，我想利用自己的UDID码简单的通过info.plist文件给这个应用加密，就是让软件不被第三方软件备份后安装到其他IPAD上用，这个程序是在越狱后的IPAD上用的，我自己能用编辑软件打开info.plist 的文件，我自己添加进去，至于命令和编程我一窍不通，真的麻烦您了，在此感谢您，我是个菜鸟，没办法，只会些简单的操作，如果需要付费我会付给您，我的这个要求真的很着急，谢谢您给指导一下吧，我的UDID是:1a2c11229a20c20030fec5294b0b6b8f70149db8
再最后感谢您的帮助，真心的希望您发大财，全家幸福健康
这个是info.plist的打开后的字符串
