A category adding support for AES encrypted key-value pairs to NSUserDefaults.
[NSUserDefaults setPassword:<#password#>];
[[NSUserDefaults standardUserDefaults] setEncryptedFloat:1.0 forKey:@"1.0"];Add
pod 'NSUserDefaults+Encryption', :git => 'https://github.com/b-andris/NSUserDefaults-Encryption.git', :tag => '1.0.0'
to your Podfile and run pod install in your project's root folder
Copy the NSUserDefaults+Encryption.h and the NSUserDefaults+Encryption.m files into your Xcode project.
All encryption is performed by RNCryptor.
NOTE: In order to enable lookup the sha256 hashes of all encrypted keys are stored in plain text making them vulnerable to dictionary attacks.
(Key meaning the argument of methods such as -[NSUserDefaults objectForKey:] and not the encryption key)
A discussion on the security implications of this can be found [here](A discussion on the security aspects of using a plaintext hash as IV : http://security.stackexchange.com/questions/4594/when-using-aes-and-cbc-can-the-iv-be-a-hash-of-the-plaintext).
- 1.0.0 Implemented a encrypted version of many documented NSUserDefaults methods.
