iPhone - AES256加密使用内置库 [英] iPhone - AES256 Encryption Using Built In Library

问题描述

嗯，我所有的使用 http://pastie.org/966473 作为参考需要做的是加密使用AES256加密的东西。我创建了一个类，将实现放在我的类的实现之上的pastie中。

  @implementation 
 // pastie code 
 @end 
 
 @implementation 
 //我的类代码
 @end 
  

在我的类代码中，我创建一个NSMutableData并尝试调用EncryptAES方法，我收到一个警告，说它可能不会响应。我在这里做错了什么？我需要在其他地方实现pastie代码吗？感谢任何帮助。

解决方案

这只是 @implementation 块。您还需要定义类别。将它放在你的头文件中：

  @interface NSMutableData（AES）
  - （NSMutableData *）EncryptAES：（NSString *）键; 
  - （NSMutableData *）DecryptAES :( NSString *）key 
 andForData：（NSMutableData *）objEncryptedData; 
 @end 
  

Hey all, I am using http://pastie.org/966473 as a reference as all I need to do is encrypt something using AES256 encrypting. I created a class and put the implementation in the pastie on top of the implementation for my class.

@implementation
//pastie code
@end

@implementation 
//my class code
@end

In my class code I create a NSMutableData and try to call the EncryptAES method and I get a warning saying it might not respond to that. What am I doing wrong here? do I need to implement the pastie code elsewhere? Thanks for any help.

解决方案

That's just the @implementation block. You also need to define the category. Put this in your header file:

@interface NSMutableData (AES)
    - (NSMutableData*)EncryptAES:(NSString *)key;
    - (NSMutableData*)DecryptAES:(NSString *)key
                      andForData:(NSMutableData*)objEncryptedData;
@end
