NSUserDefaults-AESEncryptor is a NSUserDefaults category. Its purpose to encrypt/decrypt keys and values with AES encryptor.

Requirements

NSUserDefaults-AESEncryptor works on iOS 5.0+ version and is compatible with ARC projects. It depends on the following Apple frameworks, which should already be included with most Xcode templates:

• Foundation.framework

You will need LLVM 3.0 or later in order to build NSUserDefaults-AESEncryptor.

NSUserDefaults-AESEncryptor uses CocoaSecurity to encrypt/decrypt.

Adding NSUserDefaults-AESEncryptor to your project

Source files

Alternatively you can directly add source files to your project.

1. Download the latest code version or add the repository as a git submodule to your git-tracked project.
2. Open your project in Xcode, then drag and drop all files at NSUserDefaults-AESEncryptor folder onto your project (use the "Product Navigator view"). Make sure to select Copy items when asked if you extracted the code archive outside of your project.
3. Install CocoaSecurity.

Usage

• Import NSUserDefaults+AESEncryptor.h and add this to Prefix.pch

// Set a key. (If no key is set, a default key will be used)
[[NSUserDefaults standardUserDefaults] setAESKey:@"World Cup 2014"];

// Encrypt
[[NSUserDefaults standardUserDefaults] encryptValue:@"Brazil" withKey:@"country"];

// Decrypt
NSString value = [[NSUserDefaults standardUserDefaults] decryptedValueForKey:@"country"];

// Remove object
[[NSUserDefaults standardUserDefaults] removeObjectForAESKey:@"country"];
