Android developer portal with tools, libraries, and apps
JJWT aims to be the easiest to use and understand library for creating and verifying JSON Web Tokens (JWTs).
JealousSky is an efficient library to encrypt and decrypt data for Android.
With JealousSky is possible to decrypt simple String or even image files.
This Java library provides an implementation of macaroons, which are flexible authorization tokens that work great in distributed systems.
Like cookies, macaroons are bearer tokens that enable applications to ascertain whether their holders' actions are authorized. But macaroons are better than cookies!
Kevlar is a security toolkit (library) for Android apps. It is divided in 3 packages (antipiracy, rooting and integrity), each containing specific tooling and components.
Its purpose is to be an auditing tool, used to inspect the security environment on Android devices.
A security environment is the security state of a device, which can be probed with the different packages kevlar provides.
Each package focuses on a specific security environment area:
- antipiracy detects the presence of pirate software installed on the device (user-wise security);
- rooting detects the presence of root access, custom binaries, and abnormal OS status (system-wise security);
- integrity detects certain types of tampering attempts your app may have been targeted with (app-wise security).
Kevlar is intended to be used any time it is deemed necessary to determine whether the device your app is running on can be regarded as secure, according to your policies and security requirements.
This is an lightweight library for save and get data secure into the Keystore which encrypted and decrypted.
Simple wrapper library in Kotlin is designed to save secret to local shared preferences using Android default security and Android Keystore. KeystoreCompat ensures handling LockScreen and compatibility among diversity of Android versions.
Sodium is a new, easy-to-use software library for encryption, decryption, signatures, password hashing and more.
The MSAL library for Android gives your app the ability to begin using the Microsoft Cloud by supporting Microsoft Azure Active Directory and Microsoft Accounts in a converged experience using industry standard OAuth2 and OpenID Connect. The library also supports Azure AD B2C.
This is an Android Library Project that provides multiple means to improve network security in mobile applications.
openpgp-api-lib provides methods to execute OpenPGP operations, such as sign, encrypt, decrypt, verify, and more without user interaction from background threads. This is done by connecting your client application to a remote service provided by OpenKeychain or other OpenPGP providers.
Passay is password policy enforcement for Java including password generators and validators helpers.
An Android library that prevents your app from being pirated / cracked using Google Play Licensing (LVL), APK signature protection and more.

This is a lightweight library to generate a 64-bit random key and using AES Algorithm to encrypt/decrypt that random number to get a Secret Key and save it to Key Store.
This library especially supports for Realm Encryption. That means when using you don't have to care about how to get a random key, where to save that key for safe, ... this library will take it.
Android library build on top of retrofit, for simple handling of authenticated requests.
Android JNI model implementation of Rob Napier's RNCryptor.
Small library that wraps Account manager API in RxJava Observables reducing boilerplate to minimum.
Reactive Auth APIs Wrapper Library for Google's Smart Lock for Passwords API.
Reactive extension for Google's Smart Lock for Passwords API.
Safe to run has been developed in order to simplify development of secure android applications. In particular the goal of the project is to provide a simple, configurable way for app developers to define when an app should or should not run and a simple way of calling that check.
One tool to manage key generation, key storing and encryption on different APIs of Android.
As you may know android provided API to use keystore that is stored in system only from API 18. They introduced AndroidKeyStore provider that is responsible to manage this.
But as always there are underwater stones. Up to API 23 you are only able to create asymmetric keys using AndroidKeyStore provider. Also algorithms that you can use are limited. And what about devices below API 18 ?
This project provides API that wraps default JCA api and AndroidKeyStore API and makes it easy to create, manage and use your keys on any andorid API.
This application will scan through all available secret codes on your device. Then you will be able to execute these secret codes and discover hidden functionalities.
Secrets for Android is an application to securely store and manage passwords and secrets on your Android phone. It uses techniques like strong encryption and auto-logout to help ensure that your secrets remain safe (assuming you use a good master password!). Context-sensitive tips guide you along through its operation, making it easy to use.
Storing Credentials securely on a Device is a must. To make that possible we have combined the Android Keystore for generating Cryptographic keys, and storing them securely and using those keys we encrypt the credentials and save them in the SharedPreferences.
Manage passwords like a pro with industry level features.
SimpleEncryptorLibrary is a library for encryption and decryption strings in Android apps and PC/Mac Java applications.
A library which helps developers to integrate Google Sign-in and Facebook Sign-in.
A repackage of Bouncy Castle for Android (which ships a crippled version of BC).
A sample application that can be used as a template for implementing Mobile Two Factor Auth
The major drawback of authentication performed including something that the user possesses is that the physical token (the USB stick, the bank card, the key or similar) must be carried around by the user, practically at all times. Loss and theft are a risk. There are also costs involved in procuring and subsequently replacing tokens of this kind. In addition, there are inherent conflicts and unavoidable trade-offs between usability and security.
