Usage

Learn about more advanced features in Examples ↗

See all the available features in the API documentation ↗

let simpleKeychain = SimpleKeychain()

You can specify a service name under which to save items. By default the bundle identifier of your app is used.

let simpleKeychain = SimpleKeychain(service: "Auth0")

Store a string or data item

try simpleKeychain.set(accessToken, forKey: "auth0-access-token")

Check if an item is stored

let isStored = try simpleKeychain.hasItem(forKey: "auth0-access-token")

Retrieve a string item

let accessToken = try simpleKeychain.string(forKey: "auth0-access-token")

Retrieve a data item

let accessToken = try simpleKeychain.data(forKey: "auth0-credentials")

Retrieve the keys of all stored items

let keys = try simpleKeychain.keys()

Remove an item

try simpleKeychain.deleteItem(forKey: "auth0-access-token")

Remove all items

try simpleKeychain.deleteAll()

Error handling

All methods will throw a SimpleKeychainError upon failure.

catch let error as SimpleKeychainError {
    print(error)
}

Support Policy

This Policy defines the extent of the support for Xcode, Swift, and platform (iOS, macOS, tvOS, and watchOS) versions in SimpleKeychain.

Xcode

The only supported versions of Xcode are those that can be currently used to submit apps to the App Store. Once a Xcode version becomes unsupported, dropping it from SimpleKeychain will not be considered a breaking change, and will be done in a minor release.

Swift

The minimum supported Swift minor version is the one released with the oldest-supported Xcode version. Once a Swift minor becomes unsupported, dropping it from SimpleKeychain will not be considered a breaking change, and will be done in a minor release.

Platforms

We support only the last four major versions of any platform, including the current major version.

Once a platform version becomes unsupported, dropping it from SimpleKeychain will not be considered a breaking change, and will be done in a minor release. For example, iOS 14 will cease to be supported when iOS 18 gets released, and SimpleKeychain will be able to drop it in a minor release.

In the case of macOS, the yearly named releases are considered a major platform version for the purposes of this Policy, regardless of the actual version numbers.

Missing nullable annotation for method keyRefOfRSAKeyWithTag:

Description

The method - (SecKeyRef)keyRefOfRSAKeyWithTag:(NSString *)keyTag; in the class extension A0SimpleKeychain (KeyPair) can return NULL but has no nullable annotation.

Reproduction

Choose Analyze from the Product menu in Xcode for any project with the Simplekeychain Library:

Pods/SimpleKeychain/SimpleKeychain/A0SimpleKeychain+KeyPair.m:120:9: warning: Null returned from a method that is expected to return a non-null value return NULL; ^~~~~~~~~~~

Environment

• SimpleKeychain (0.10.0)
• Target platform iOS 10

TouchID does not show up

I've tried to implement A0SimpleKeychain in my project - but for some reason the TouchID does not show up. It seems like I'm not able to store anything in the Keychain - as the id changes every time I execute the app.

Here's my code:

var error: NSError?
let message = "Please login"
let keychain = A0SimpleKeychain()
var defaultAccount = keychain.stringForKey("default.account", promptMessage: message)

if defaultAccount == nil {
    let uuid = NSUUID().UUIDString.stringByReplacingOccurrencesOfString("-", withString: "", options: nil, range: nil).lowercaseString

    defaultAccount = NSString(string: uuid)

    let keychain = A0SimpleKeychain()
    keychain.useAccessControl = true
    keychain.defaultAccessiblity = .WhenPasscodeSetThisDeviceOnly
    keychain.setString(defaultAccount, forKey: "default.account")
}

println(split( defaultAccount ){ $0 == "$" })

What I'm doing wrong?

'keychain()' is unavailable error with Swift

Hi guys,

This line from the README :
A0SimpleKeychain.keychain().setString(jwt, forKey:"auth0-user-jwt")
gives me the following error :
'keychain()' is unavailable: use object construction 'A0SimpleKeychain()'

After reading the code a bit more, I changed the line to this and it works :
A0SimpleKeychain().setString(jwt, forKey:"auth0-user-jwt")

I'm not too sure why but it looks like the conversion from obj-c to swift is not working as expected, any ideas?

I'm using Xcode 6.1

No way to disable useAccessControl

Description

I'm trying to request Biometric only once, for that I deal with biometric by my own and use the keychain without access control, but there is no way, I ended by prompting for FaceId several times and is very annoying.

I guess it is related to #78.

Reproduction

final class KeychainManager {
    static let shared = KeychainManager()
    // MARK: - private methods
    private lazy var defaultKeychain: A0SimpleKeychain = {
        let keychain = A0SimpleKeychain(service: App.shared.isProductionRunEnvironment ? "Auth0" : "Auth0-STAGE")
        keychain.useAccessControl = false
        return keychain
    }()
    private lazy var context: LAContext = {
        var context = LAContext()
        context.touchIDAuthenticationAllowableReuseDuration = 60
        return context
    }()

    // MARK: Public methods
    func getPasswordWithBiometricAuth(_ completion: @escaping (String?) -> Void) {
        var error: NSError?
        if context.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: &error) {
            log.debug("canEvaluatePolicy")
            context.evaluatePolicy(.deviceOwnerAuthenticationWithBiometrics,
                                   localizedReason: NSLocalizedString("KeychainManager.shared.passwordPromptMessage",
                                                                      comment: "")
            ) { (success, _) in
                log.debug("policy with \(success ? "success":"failure")")
                if success,
                    let email = Defaults[.rememberedEmail],
                    let password = self.defaultKeychain.string(forKey: "\(email).password") {
                    completion(password)
                } else {
                    completion(nil)
                }
            }
        } else {

Starting in spring 2024, you must include the privacy manifest for any SDK listed below when you submit new apps in App Store Connect that include those SDKs, or when you submit an app update that adds one of the listed SDKs as part of the update. Signatures are also required in these cases where the listed SDKs are used as binary dependencies.

Could you please add a privacy manifest for this library?

Update dependency (Quick)

Trying to add latest versions of Quick & Nimble frameworks into my project via SPM. But getting following error:

Dependencies could not be resolved because root depends on 'Quick' 4.0.0..<5.0.0 and root depends on 'SimpleKeychain' 0.12.2..<1.0.0.
'SimpleKeychain' >= 0.12.2 practically depends on 'Quick' 3.0.0..<4.0.0 because 'SimpleKeychain' 0.12.2 depends on 'Quick' 3.0.0..<4.0.0 and no versions of 'SimpleKeychain' match the requirement 0.12.3..<1.0.0.

Could you please update SimpleKeychain to use latest Quick & Nimble versions?

Also I was wondering if it is worth having these dependencies (Quick & Nimble) in such a small framework like SimpleKeychain. It contains only 20± unit tests. Please consider rewriting them using XCTest. Framework will become lighter and you will lose additional 3rd party dependencies.

Migration ObjC SimpleKeychain to Swift

Hello Guys I'm migrating old app wrote in ObjC to Swift, When I try to access to the stored keys but I can't access to the value. But In ObjC app I can, I'm no sure why, I check all possibilities and all is OK could you help me?

Describe the problem you'd like to have solved

From Spring 2024, apps that don’t describe their use of required reason API in their privacy manifest file won’t be accepted by App Store Connect.

Although Pushwoosh SDK isn't mentioned in Apple's provided list of SDKs (see link below), considering Apple's strict privacy policies, you should add the Privacy Manifest file on your own before it comes into their notice. Lots of the SDKs (Firebase, Facebook, Alamofire, etc.) have already updated their SDKs and added the required privacy manifest file.

Keychain data getting lost on app upgrade

Description

I am storing JWT token in keychain using -

A0SimpleKeychain().setString(token, forKey:"user-jwt")

And using the following to retrieve it back -

A0SimpleKeychain().string(forKey: key)

I am seeing in production logs that for some users, token is not getting fetched from keychain after app upgrade. Is it iOS issue or anything I am missing out here. Please suggest.

Environment

• Version of SimpleKeychain used: 0.9.0
• Version of OS used: 12.4
• Additional dependencies that might be relevant:
• If using Carthage or CocoaPods, please include your Cartfile or Podfile
  Podfile.txt
• Xcode version: 10.3

Cannot set string in simulator.

Hello;

I am trying this code in simulator. But it doesn't work. token is nil.

 [[A0SimpleKeychain keychain] setString:value forKey:key];
 NSLog(@"token is %@", [[A0SimpleKeychain keychain] stringForKey:key]);

If I run this in a device, it works.

What is wrong?

Crash on setData Auth0.Profile

Using this
keychain.setData(NSKeyedArchiver.archivedDataWithRootObject(profile), forKey: "profile")
from the Auth0 documentation: https://auth0.com/docs/quickstart/native/ios-swift/03-session-handling#validate-an-existent-idtoken

The application is crashing and returning this:

Xcode 8 / Swift 2.3 : keychain.setString returns false

Hi,

My code was working fine until I migrated to XCode 8 / Swift 2.3.
It is inspired from the Auth0 documentation.
Basically, now, keychain.setString always return false.
So my class property currentIdToken is nil.

Any ideas ?

Thanks
Fred

Describe the problem you'd like to have solved

The primary issue I'm encountering involves the lack of a feature for handling privacy manifests within the JWTDecode.swift library. As per the new App Store guidelines effective from May 1, 2024, all applications are required to include a privacy manifest. This is crucial for ensuring that our app remains compliant with App Store policies and avoids any potential disruption in service or availability on the App Store.

Describe the ideal solution

The optimal solution would be for JWTDecode.swift to integrate a feature that allows for easy creation and management of privacy manifests in accordance with the upcoming App Store requirements. This would ideally include functionalities to specify the data types accessed or collected by our application and any third-party integrations, ensuring a seamless process for developers to declare their app's privacy practices transparently. Such an update would greatly assist in maintaining the app's compliance and streamline the development process for all users of your library.

Carthage - "dyld: Library not loaded"

I have attempted to install SimpleKeychain via Carthage via the following steps:

1. Add "github "auth0/SimpleKeychain"
   " to Cartfile
2. Run "Carthage update"
3. Link build phases Carthage to directory "$(SRCROOT)/Carthage/Build/iOS/SimpleKeychain.framework"

When I try to build the project in Xcode I receive the following compiler error:

dyld: Library not loaded: @rpath/SimpleKeychain.framework/SimpleKeychain
Referenced from: /Users//Library/Developer/Xcode/DerivedData//Build/Products/Debug-iphonesimulator/Login.framework/Login
Reason: image not found

Has anyone found a way around this and installing Simple Keychain via Carthage?

Move to Circle CI

Enhancement: Update to swift 1.2

It would be nice to have the framework updated to 1.2

User Presence Missing SecAccessControl options

Currently the .useAccessControl property sets the kSecAccessControlUserPresence access control option.

There are stronger options that are not currently supported:

kSecAccessControlTouchIDCurrentSet
kSecAccessControlTouchIDAny

The full list can be found here: https://developer.apple.com/reference/security/secaccesscontrolcreateflags?language=objc

Code Errors in Your README.

You should update this project's README to fix the typos when documenting code.

Particularly when you are talking about using Touch ID, the code provided has errors:

keychain.useAcessControl = true keychain.defaultAccesiblity = .WhenPasscodeSetThisDeviceOnly

They should be:

keychain.useAccessControl = true keychain.defaultAccessiblity = .WhenPasscodeSetThisDeviceOnly

The differences are subtle but naturally they don't allow the code to compile. Please update the snippet I mentioned with the one I just gave you. Thanks!

Xcode analysis raises 'nil value' issue

Here's the message I'm getting from Xcode CI.

Bot Issue: analyzerWarning. API Misuse (Apple).
Issue: Value stored into 'NSMutableDictionary' cannot be nil.
File: A0SimpleKeychain.m.
Description: Value stored into 'NSMutableDictionary' cannot be nil.

It takes me to line 285 of A0SimpleKeychain.m.

-[A0SimpleKeychain queryNewKey:value:] leaks accessControl

On iOS 8, accessControl is created, added to the query, and then it's never released. The query dictionary takes it's retain, but the method does not give up its retain.

Xcode 7, beta 5 analyzer will show the issue as well.

Keychain values stay after deleting the app

When I login with Auth0, I save the profile and the id_token using A0SimpleKeychain. Is it normal that once I delete the app and reinstall it, the keychain is still there? If it's normal, it's only available from my app right?

Thanks

how to disable touch ID dialog

Hi, I would like to access the keychain on iOS 8 without the keychain showing up. Do you know how i can achieve this?

This is me accessing it in swift. I know the sample project works in objective c, and you can access the keychain without the touchID prompt. Doesn't seem to work the same way with swift.

Let me know.
Cheers :)

Does not work in iOS13.4 simulator

Description

When using the iOS13.4 simulator, SimpleKeychain reports that it saved successfully. When I try to retrieve the saved object, I get empty data.

Reproduction

• Add this to a fresh Xcode project , e.g. in the AppDelegate.

let keychain = A0SimpleKeychain()
keychain.setString("foo", forKey: "f")
let string = keychain.string(forKey: "f")!
assert(string == "foo")

• Run on iOS 12.4 sim, no assert.
• Run on iOS 13.4 sim, assertion failed.

Environment

• Version of this library used: 0.11.0
• Version of the platform or framework used, if applicable: iOS 13.4 simulator

App transfer, keychain loss

Hi,

I have transferred my app to another account.
I was using SimpleKeychain without setting service name and access group.

Nevertheless, i cannot reach my keychain data which is saved before transferring my app.
How can i solve this problem?

stringForKey always returns null on iOS8

I'm using a cordova plugin that leverages this project and I'm encountering an issue where stringForKey always returns null, I've experienced this on iOS 8 and there is a report of it happening on iOS 9.2, but it seems ok on iOS 9.3. I'm also seeing an exception on a iOS 9.2 device (as a bonus issue). Any chance I could get your input?

Nullability Static Analysis warnings in Xcode 8 (8A218a)

All of the methods in the A0SimpleKeychain header are enclosed in NS_ASSUME_NONNULL_BEGIN/NS_ASSUME_NONNULL_END but several of the data/string setter methods allow for nil handling in the implementation.

This generates static analysis warnings in Xcode 8.

Problem setting custom prompt message when app asks for Touch ID/Passcode

Hi,

I'm having trouble trying to set a custom prompt message when accessing Keychain.

I followed the documentation and set a new NSString with my custom message:

NSString *message = NSLocalizedString(@"msg.keychain.prompt", nil);
NSString *savedValue = [keychain stringForKey:@"value" promptMessage:message];

The problem is: The message doesn't show up. I tried to debug to see if I can find the problem and when the code reaches the method - (NSDictionary *)queryFetchOneByKey:(NSString *)key message:(NSString *)message { everything is nil, including message. Therefore the message isn't displayed.

I'm running pod version 0.7.0.

Any help is appreciated. Thanks!

Always getting "Error trying to access to non available kSecUseOperationPrompt in iOS7" log

I'm trying to use this on ios 7 and 8, so if I'm not using user access control and kSecUseOperationPrompt either, but I'm always getting this error log in the query.
Shouldnt it be like this? :

• (NSDictionary *)queryFetchOneByKey:(NSString *)key message:(NSString *)message {
  NSMutableDictionary *query = [self baseQuery];
  [query addEntriesFromDictionary:@{
  (__bridge id)kSecReturnData: @yES,
  (__bridge id)kSecMatchLimit: (__bridge id)kSecMatchLimitOne,
  (__bridge id)kSecAttrAccount: key,
  }];

  if TARGET_OS_IPHONE

  if (message) {
  if (self.useAccessControl && floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_7_1) {
  query[(__bridge id)kSecUseOperationPrompt] = message;
  } else {
  NSLog(@"Error trying to access to non available kSecUseOperationPrompt in iOS7");
  }
  }

  endif

  return query;
  }

EXC_BAD_ACCESS in dataForKey - release 0.11.0

Description

When calling .dataForKey, I intermittently crash my app on the following EXC_BAD_ACCESS. I am always passing the same Key into the method to retrieve the user's "token" from KeyChain. I expect to always receive my token, or nil.

Reproduction

I seem to see this crash after one of two things:

1. High frequency requests from the UI to retrieve the user's token, OR
2. A certain number of requests to retrieve the user's token has been reached

The reason I raise item 2 is that the issue only happens after a while in my app's lifecycle, (i.e. after it has been used to do a certain number of things).

Environment

• SimpleKeyChain version 0.11.0
• Xcode version 11.3.1 (11C504)
• iOS version 13.3.1

Thank you. Please let me know if I can provide any further information?

Default accessiblity should be kSecAttrAccessibleWhenUnlockedThisDeviceOnly

Right now accessibility is kSecAttrAccessibleAfterFirstUnlock which basically means always available even when device locked is and has not been rebooted recently....

A more sensible default should be kSecAttrAccessibleWhenUnlockedThisDeviceOnly otherwise it's easy for a programmer to leave the default assume it's protected well.

No Swift interface for new additions

Description

I'm not able to access to some the new features added with #74 on Swift code.

Reproduction

I'm trying to deal with biometric authentication by my own, so I want to pass my own LAContext to the A0SimpleKeychain instance but there is no way, the interface isn't accessible in Swift.

Environment

In my Podifle:

    pod 'Auth0', '~> 1.21'
    pod 'SimpleKeychain', '~> 0.10'

My project supports iOS 11.4 in advance.

Under swift, do I need to import the security framework manually to use the keychain?

Hello there,
I'm using the KeychainWrapper in my project and everything works fine but now I wonder about the need for the security framework which I didn't import manually. Is this something I still need to do in swift? I can Cmd+click those kSec keys in the wrapper and it sends me to the security framework - does this mean it's "built in" into swift now or something like that?

If I do need that framework why does it work right now "without" it? Are my strings saved but not encrypted or something like that?

Btw: I asked that on SO as well but the answers weren't completely satisfying thats why I ask here now.

Thanks a lot in advance

tvOS 12: Sharing values with Access Group doesn't work

Hi, I am trying to share access token to topShelf extension on tvOS, but I always get a nil values.
Sharing is not supported on tvOS or Am I doing anything wrong?
App:
let keychain = A0SimpleKeychain(service: Auth0Key.SERVICE.rawValue, accessGroup: Auth0Key.GROUP.rawValue)

keychain.setString("pokus", forKey: "pokus")`

topShelf:
let keychain = A0SimpleKeychain(service: Auth0Key.SERVICE.rawValue, accessGroup: Auth0Key.GROUP.rawValue)

let value = keychain.string(forKey: "pokus")

Local Authentication is not reused

By submitting an Issue to this repository, you agree to the terms within the Auth0 Code of Conduct.

Description

When keychain's accesibility is configured as afterFirstUnlockThisDeviceOnly and useAccessControl is true, the device prompts the unlock password, once per access to keychain (either it's for setting or getting a key's value).

As specified at https://developer.apple.com/documentation/localauthentication/accessing_keychain_items_with_face_id_or_touch_id the keychain default's behavior is to create a new LocalAuthentication every time it's used. A LocalAuthentication context must be created and reuse in order to avoid this behavior (which leads to poor UX)

Reproduction

keychain = A0SimpleKeychain()
keychain.useAccessControl = true
keychain.defaultAccessiblity = .afterFirstUnlockThisDeviceOnly

keychain.setString("TEST 1", forKey: "KEY 1", promptMessage: "Write KEY 1")
keychain.setString("TEST 2", forKey: "KEY 2", promptMessage: "Write KEY 2")
keychain.setString("TEST 3", forKey: "KEY 3", promptMessage: "Write KEY 3")

let v1 = keychain.string(forKey: "KEY 1", promptMessage: "Read KEY 1")
let v2 = keychain.string(forKey: "KEY 2", promptMessage: "Read KEY 2")
let v3 = keychain.string(forKey: "KEY 3", promptMessage: "Read KEY 3")

Handle Touch ID errors when retrieve data from keychain - Swift

Hi!
I have a doubt. Is there a way to handle the errors if touch ID not matching? For example, if user tap on cancel button (in touch ID dialog).

Thanks!

Error in CircleCI pipeline: Duplicate symbol due to code coverage
