NitroKeychain

NitroKeychain is a thin, yet powerful, abstraction layer on top of iOS keychain that provides commonly needed features. NitroKeychain is also thread safe.

There are 3 operations: save, load and delete, as you can see below:

Saving

Objective-C

[TNTKeychain save: @"com.myapp.service.id" 
             data: @"my-ultra-secret-token"];
             
// Or, if you want to make this item available across apps, specify 
// an access group:
[TNTKeychain save: @"com.myapp.service.id" 
             data: @"my-ultra-secret-token"
      accessGroup: @"super-company"];

Swift

TNTKeychain.save("com.myapp.service.id", data: "my-ultra-secret-token")
             
// Or, if you want to make this item available across apps, specify 
// an access group:
TNTKeychain.save("com.myapp.service.id", 
                  data: "my-ultra-secret-token", 
                  accessGroup: "super-company")

• All keychain items are stored using the kSecClassGenericPassword Keychain Item class.
• data can be any value compatible with NSKeyedArchiver/NSKeyedUnarchiver.
• If there is already some data associated with a keychain item ID, it will be updated.

Loading

Objective-C

NSString *token = [TNTKeychain load: @"com.myapp.service.id"];
NSLog( @"%@", token );

• load will return nil if no keychain item is found with such id.

Swift

let token = TNTKeychain.load("com.myapp.service.id")
print(token)

Deleting

Objective-C

[TNTKeychain delete: @"com.myapp.service.id"];

• delete does nothing if no keychain item is found with such id.

Swift

TNTKeychain.delete("com.myapp.service.id")

Simple as that 👍

Requirements

iOS 6.0 or higher, ARC only
