Sodium is a new, easy-to-use software library for encryption, decryption, signatures, password hashing and more.
JJWT aims to be the easiest to use and understand library for creating and verifying JSON Web Tokens (JWTs).
Android application compatible with ZX2C4's Pass command line application.
This is a reference guide for Android Security things.
Windows Azure Active Directory Authentication Library (ADAL) for Android.
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.
Reactive extension for Google's Smart Lock for Passwords API.
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!
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.
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.
A repackage of Bouncy Castle for Android (which ships a crippled version of BC).
An Android library that prevents your app from being pirated / cracked using Google Play Licensing (LVL), APK signature protection and more.
A small and simple library for managing trial period in your android app.
Android library build on top of retrofit, for simple handling of authenticated requests.
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.
Android JNI model implementation of Rob Napier's RNCryptor.
Conceal provides a set of easy to use APIs for performing fast encryption and authentication of data. Apps can use Conceal to encrypt data and large files stored in public locations, for example SD cards.
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.
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.
A simple way to encrypt your secure data like passwords into a native .so library.
Encryption is a simple way to create encrypted strings to Android project.
