This is a reference guide for Android Security things.
Android application compatible with ZX2C4's Pass command line application.
A simple library for supporting self-signed certificates in Android.
AndroidPinning is a standalone Android library project that facilitates certificate pinning for SSL connections from Android apps, in order to minimize dependence on Certificate Authorities.
AndroidTampering is a library that provides an extra layer of security to your Android application. This library protects your application against simple tampering attacks. Please note that this protection methods can also be hacked. So, besides the tampering protection, don't forget to add all the other security recommendations.
AuthManager is a library which eliminates the boilerplate of Google SignIn and SmartLock integration.
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 way to encrypt your secure data like passwords into a native .so library.
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.
A library for encryption/decryption and digitally media (photo/video) signing/verifying.
A simple Android Library for performing encryption with AES.
This project helps to use elliptic curve cryptography (ECC) with Curve25519.
Extensions to encrypt DataStore using Tink.
⚠️ This tiny library will be maintained until an official solution for DataStore encryption will be released by Google.
Encryption is a simple way to create encrypted strings to Android project.
It`s a simple java library for encryption. This library contains next encryption methods:
- AES
- ARCFOUR
- Blowfish
- DES
- DESede
- RSA
- HMAC
- PBE
It`s realy easy to use.
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 heuristic evasion library for Android. A KTX scoping function that prevents code from analysis.
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.
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.
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.
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.
