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).
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.
Windows Azure Active Directory Authentication Library (ADAL) for Android.
Android application compatible with ZX2C4's Pass command line application.
SQLCipher is an open source extension to SQLite that provides transparent 256-bit AES encryption of database files.
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.
Sodium is a new, easy-to-use software library for encryption, decryption, signatures, password hashing and more.
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.
This is a reference guide for Android Security things.
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.
Extensions to encrypt DataStore using Tink.
⚠️ This tiny library will be maintained until an official solution for DataStore encryption will be released by Google.
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!
Heimdall is an OAuth 2.0 client specifically designed for easy usage and high flexibility. It supports all grants as described in Section 4 as well as refreshing an access token as described in Section 6 of the The OAuth 2.0 Authorization Framework specification.
Reactive extension for Google's Smart Lock for Passwords API.
A repackage of Bouncy Castle for Android (which ships a crippled version of BC).
A small and simple library for managing trial period in your android app.
This is an Android Library Project that provides multiple means to improve network security in mobile applications.
Android library build on top of retrofit, for simple handling of authenticated requests.
An Android library that prevents your app from being pirated / cracked using Google Play Licensing (LVL), APK signature protection and more.
A heuristic evasion library for Android. A KTX scoping function that prevents code from analysis.
Android JNI model implementation of Rob Napier's RNCryptor.
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.
BillingProtector is a small Android library aiming to check the device state & purchases security. Its main purpose is to block a transition if the application has been modified or patched; it can also be used to prevent applications from being executed on an unprotected/insecure environment.
IOCipher provides a virtual encrypted disk for Android apps without requiring the device to be rooted. It uses a clone of the standard java.io API for working with files, so developers already know how to use it. Only password handling, and opening the virtual disk are what stand between the developer and working encrypted file storage. It is based on and SQLCipher.
SimpleEncryptorLibrary is a library for encryption and decryption strings in Android apps and PC/Mac Java applications.
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.
A library for encryption/decryption and digitally media (photo/video) signing/verifying.
Now make your applications more secure with Hasher. Simple and easy to use Hashing library that enables you to Hash in MD5 (Message Digest), SHA-1, SHA-256, SHA-392, and SHA-512.
Encryptor4j consists of a set of wrapper and utility classes that make leveraging cryptography in your application alot easier.
It enables developers to encrypt and decrypt with little room for error, using few lines of code and supports all popular encryption algorithms such as AES, DES, RSA etc.
