A heuristic evasion library for Android. A KTX scoping function that prevents code from analysis.
An open source app locker, vault, call blocker application.
A library for encryption/decryption and digitally media (photo/video) signing/verifying.
This project is created to provide standards for Android application security before making it live to Google Play.
The Hardware Security SDK is the best framework for using Security Keys (YubiKeys, Nitrokeys, …) and smart cards on Android. It supports NFC and USB connections.
Our SDK extends your app with:
A small and simple library for managing trial period in your android app.
This is an lightweight library for save and get data secure into the Keystore which encrypted and decrypted.
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.
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.
A simple Android Library for performing encryption with AES.
A demo of how to implement AES encryption in Android & iOS.
A simple way to encrypt your secure data like passwords into a native .so library.
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.
Email and password signup is a technology that has not been innovated on in decades. Signup forms are cumbersome and repetitive. When users forget their credentials and fail to sign in, you can lose customers. So, that's why here twitter digits comes in picture.
Reactive Auth APIs Wrapper Library for Google's Smart Lock for Passwords API.
Secure and efficient cryptography library for Android. (Auto fix SecureRandom bugs in API 18 and below.)
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.
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.
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.
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.
It`s a simple java library for encryption. This library contains next encryption methods:
It`s realy easy to use.
Passay is password policy enforcement for Java including password generators and validators helpers.
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 is a reference guide for Android Security things.
Password Utility Free Forever
This is an encryption example of RSA and AES (CBC, ECB, CTR) 256 bit key on android with unit tests.
AuthManager is a library which eliminates the boilerplate of Google SignIn and SmartLock integration.
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.
