将NSUserDefaults转换为钥匙串? [英] Converting NSUserDefaults to Keychain?

问题描述

因此，NSUserDefaults非常易于使用.但是显然，它不是太安全-没有加密.当然，客户端希望应用程序安全，因为它包含敏感数据.

So, NSUserDefaults is quite easy to use. But apparently, it is not too secure - there is no encryption. And of course the client wants the app prefs to be secure because it contains sensitive data.

但是钥匙链是安全的，尽管很难编码(显然).那么有没有一种方法可以轻松地将NSUserDefaults代码转换为Keychain代码?换句话说，我想将应用程序偏好存储在钥匙串中.还是我吠错了树?

But the Keychain is secure, though hard to code (apparently). So is there a way to easily convert NSUserDefaults code to Keychain code? In other words, I want to store app prefs within the Keychain. Or am I barking up the wrong tree?

推荐答案

以下两种解决方案都是KeyChain API的包装器.通过在NSUserDefaults类别中使用它们，您可以拥有一种干净的方法来访问和存储密码.

Both of the below solutions are wrappers around KeyChain API. By using them in a NSUserDefaults category, you can have clean way to access and store passwords.

您可以尝试 EMKeyChain 库，该库以友好的方式包装了钥匙串.如果您需要存储密码，则就像NSUserDefaults一样简单.

You can try the EMKeyChain library that wraps the keychain in a friendly manner. If you need to store passwords, it is as simple as NSUserDefaults.

有一个简单的包装器:简单的iPhone钥匙串代码.

There is a simple wrapper: Simple iPhone Keychain Code.
