react-native-keychain: Android UI freezing on launch

I’m experiencing problems with react-native-keychain on Android which unfortunately forces me to disable the library for Android (on iOS it works flawlessly). Sometimes the UI freezes for several seconds shortly after launching the app. This happens when simply importing the library without even using it, as in the following code:

// App.js
import React, {Component} from 'react';
import {TextInput,} from 'react-native';
import 'react-native-keychain';

export default class KeychainExample extends Component {
  render() {
    return (
      <TextInput
        style={{flex: 1}}
      />
    );
  }
}

As you can see in the screen recording below, the UI freezes and ignores any input for several seconds shortly after reloading the app.

Logcat shows a couple of errors, but I don’t know if they are related:

@oblador Are there any plans for an official fix for this on the native side of this lib?

SudoPlz on Apr 22, 2021

Still on 6.1.1 here and was also experiencing UI freeze on devices. It was locking the whole phone up. I found the culprit. It was related to the RSA cipher. It was taking a long time to load on devices especially ones with biometrics. As I was not using biometrics part of the keychain package and supporting API 23+, I decided to patch the build. The patch commented out the facebook (yuck) and RSA option. I now only work with the AES cipher and it super fast again. (Phew. I was blaming the size of the android bundle and thought Android was slow at parsing the bundle on load).

NB: This was a solution for my app as I’m only concerned about AES cipher. It will not work for everyone The patch package. https://www.npmjs.com/package/patch-package

The patch code:

  diff --git a/node_modules/react-native-keychain/...
  /** Default constructor. */
  public KeychainModule(@NonNull final ReactApplicationContext reactContext) {
    super(reactContext);
    prefsStorage = new PrefsStorage(reactContext);

    -- addCipherStorageToMap(new CipherStorageFacebookConceal(reactContext));
    addCipherStorageToMap(new CipherStorageKeystoreAesCbc());

    // we have a references to newer api that will fail load of app classes in old androids OS
    -- if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    --   addCipherStorageToMap(new CipherStorageKeystoreRsaEcb());
    -- }
  }

The technical part: pre-warming the RSA cipher (calculating that vast 2048 bit prime number) plus when the exception handler took an eternity to roll up the stack and then the next step was to re-run the pre-warming with the biometrics enabled.

WilliamAlexander on Dec 2, 2020

@SudoPlz Yes. Patch the package as suggested above to remove the initial freeze, or force the use of AES by using the STORAGE_TYPE option. The problem is that the AES option is incompatible with the user interaction requirement (biometric or password).

Under the hood

To improve on my previous comment, here is what actually happens. A secure hardware generates the keys: either a secret symmetric key (AES) or a private-public key pair (RSA) in our case. That AES key or RSA public key is used to encrypt your item value and store the encrypted result on a public file. The security lies in the fact that the secure hardware makes sure that only your app can retrieve the key. You can also specify options so that the secure hardware reveals the key only after the user has authenticated with biometrics or password.

The problem on Android is that if you specify that option for an AES key, to be able to encrypt your entry value with the newly created key, you would have to authenticate. So the user experience would be weird: the user types his password, then has to use his fingerprint or device password right after so the app can save the password… That is the reason why, I suppose, the authors of the library decided that in order to enable this option, the best way was to generate an RSA key pair. Indeed, the public key of the RSA key pair is always available… since it is public.

Then came the drawback that generating an RSA key pair is a random process, so it sometimes takes a long time. I suppose the authors of the library thought the problem was the time it took to load the library, and decided to add a warming up mechanism, which is of course not a solution and makes the problem even worse.

There are several alternatives here: 1/ keeping the current RSA implementation and accepting the key generation time randomness (maybe adding a message for the user) 2/ using an AES key without the biometric/password requirement at the hardware level while still requiring it programmatically (perfect UX, but lower theoretical security though still very good) 3/ using an AES key with the biometric/password requirement at the hardware level (highest security) with a UX compromise (requiring authentication right after key generation)

In any case, the warming up mechanism should be removed.

I have implemented 2/ on my project with a simplified api. I can send you the code if you wish.

arpitgarg23 on May 21, 2021

Hello, I have taken a great inspiration from this module to write my own (because I like to understand stuff). Thank you by the way for your work !

I didn’t investigate this issue in particular, but I was surprised when I saw the warming up mechanism in the code. This mechanism generates a “warmingUp” key which has no other purpose.

I don’t know if you are aware, but if the chosen algorithm is RSA, it will take a lot of time to generate a key pair. Just try to generate an RSA key pair in your terminal with ssh-keygen, you’ll see that takes a noticeable time. Generating an RSA key pair is a random process. The algorithm tests a lot of random numbers until it finds a prime one that’s big enough and then derives the private and the public key from it. So the generation can be quick or really long. It both depends on the speed of your processor and on luck.

I believe this slowness issue will be solved once you remove your warmup mechanism as @cladjules commented. And from my understanding of the library, it has no other side effect.

You could also use the AES algorithm instead of the RSA one. It’s as secure for this use case. (But generating a key in the Keystore with the option “setUserAuthenticationRequired(true)” and immediately use it to encrypt the user password will fail if the user does not authenticate in between. I guess that’s precisely why the RSA algorithm was used in the first place).

I hope this helps.

giregk on Aug 26, 2020

I don’t know if I did anything wrong with my tests, but selecting AES with my current config which now looks like this:

public static RAW_CREDS_CONFIG: Keychain.Options = {
    accessControl: Keychain.ACCESS_CONTROL.BIOMETRY_ANY,
    accessible: Keychain.ACCESSIBLE.WHEN_UNLOCKED,
    authenticationPrompt: {
      title: 'Unlock to log in',
    },
    storage: Keychain.STORAGE_TYPE.AES
  };

seems to have worked without any hustle. Saving the credentials went down from 1 second to 0.1 second and I can use biometrics just fine.

SudoPlz on Oct 8, 2020

@SudoPlz I think you should read the native code. I promise it will help you.

It’s the whole logic. But .setUserAuthenticationRequired(true) is the line that creates the secure-hardware requirement to use biometrics or device password. It won’t be enough to change juste this line though.

giregk on Oct 8, 2020

@SudoPlz yes

=== EDIT

…assuming you use the lib as is. If you rewrite the lib from scratch, AES can work.

=== EDIT 2 Wrong! as shown in below comment

About FB vs RSA vs AES

stands for Facebook: this will use Facebook Conceal, a deprecated library that was used in the old times to encrypt the content. This does not use any secure mecanism. I don’t know exactly how it works, but basically the secret key will be stored alongside the encrypted content so anyone who has access to the file can uncrypt what you put in the keychain. It’s not a security, it’s just obfuscation.
RSA and AES are two standard cryptographic algorithms
- RSA is an asymmetric algorithm, meaning the key that is used to encrypt is different than the key that is used to uncrypt. We call those keys a “public-private key pair”. The private key has to remain secret while the public does not. They go together. If you encrypt a message with the public key, only the person that knows the private key can uncrypt it.
- AES is a symmetric algorithm, meaning the same key is used to encrypt and uncrypt the message. That key has to remain secret, so it’s called a “secret key”.

You can find a lot more details on the web about these two algorithms.

The lib chooses the algorithm for you depending on your parameters if you don’t specify it.

About your use case

Your NO_BIOMETRICS_CONFIG should not specify the storage type to let the lib decide for you. I can’t remember exactly how the code decides, but I think it won’t use RSA unless you specify the biometric requirement. (But I’m not sure)

In the case of your RAW_CREDS_CONFIG, my solution 2/ is fine. Biometrics is not really a security improvement anyways, so let’s consider it simply as a a means to improve the UX. Here is the code I use in my project: https://github.com/giregk/react-native-simple-keychain. The api is a bit different though. Do read the native code, it will help you.

giregk on Oct 8, 2020

Experiencing the same issue on our app as well. Managed to work around the issue by disabling autolinking and adding the non warmed up module to my app.

Would be nice if the library would support loading it without necessarily performing the warmup on start, and then allow developers to explicitly control when to perform the warmup with some warmup() function.

For anyone wanting to do a similar workaround, these are roughly the changes I did.

react-native.config.js: Disable autolinking

module.exports = {
  dependencies: {
    'react-native-keychain': { platforms: { android: null } },
  },
};

settings.gradle: Add the project

include ':react-native-keychain'
project(':react-native-keychain').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-keychain/android')

app/build.gradle: Add the dependency

dependencies {
    implementation project(':react-native-keychain')
}

ColdKeychaingPackage.java: Separate non-warmupping package

package example;

import androidx.annotation.NonNull;

import com.facebook.react.ReactPackage;
import com.facebook.react.bridge.JavaScriptModule;
import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.uimanager.ViewManager;

import java.util.Collections;
import java.util.List;

import com.oblador.keychain.KeychainModule;

@SuppressWarnings("unused")
public class ColdKeychainPackage implements ReactPackage {

  public ColdKeychainPackage() {

  }

  @Override

  }

  @NonNull

    return Collections.emptyList();
  }

  @Override
  @NonNull
  public List<ViewManager> createViewManagers(@NonNull final ReactApplicationContext reactContext) {
    return Collections.emptyList();
  }
}

MainApplication.java: Add the cold keychain package

        @Override
        protected List<ReactPackage> getPackages() {
          @SuppressWarnings("UnnecessaryLocalVariable")
          List<ReactPackage> packages = new PackageList(this).getPackages();
          // Packages that cannot be autolinked yet can be added manually here, for example:
          // packages.add(new MyReactNativePackage());
          packages.add(new ColdKeychainPackage());
          return packages;

for background thread it can be ok to be a little slower, but not 28 seconds… this is tooo long

Could you please use this APK and attach here the report it produced? get-device-info.apk.zip

Since a concern was expressed about safety of this APK, I would like to assure you gentlemen that this APK is not malicious. It requests no permissions so it cannot harm your system.

Alternatively, you can clone the source from this repo and run it in Android Studio.

@jenskuhrjorgensen @Nullabl3 @cladjules @maherzaidoune @pwneth Please use either way to produce the log. Without this information we won’t be able to reproduce the issue.

john-y-pazekha on May 29, 2020

i’ve faced the same issue, the warming process took long time , that cause UI freezing on low performance phones, i specified the STORAGE_TYPE , (AES in my case) and comment the code as in the image

And did that help on performance or what is your conclusion?

Well yes, as i’m using RSA ,i didn’t need to add Facebook || AES. The last screenshot (just edited my answer), i just needed to create an instance of Cipher , that reduce the warming up time from 20s to 2s (Huawei y7 pro)

maherzaidoune on Apr 23, 2020

I did, and in particular this looked extreme: 2020-03-15 18:15:20.067 19347-32637/com.keychainexample V/RNKeychainManager: warming up takes: 17296 ms

yep… but that a complete module warmup… it triggers maximum things that’s are in the module to force java load classes and initialize them. I think you can investigate deeper with android studio profiler and see which method takes the most of the time.

low level crypto/keystores api itself is very slow… I have no idea why it so
