## What it is
An Android NDK library that implements ChaCha20-Poly1305 encryption via libsodium, with keys hidden in native code to resist reverse engineering. It adds signature verification, anti-debugging, emulator detection, and C code obfuscation to prevent repackaging attacks.

## Use cases
- hide encryption keys in native code on android
- prevent apk repackaging and second-packing
- encrypt sensitive data with chacha20 in android app
- add signature verification to android jni methods
- protect android app against reverse engineering
- detect emulators and debuggers at runtime in android

## When to choose
- you need to protect cryptographic keys from extraction in an Android app
- you want anti-tampering measures like signature verification and anti-debugging bundled together
- you prefer ChaCha20 performance on ARM over AES

## When to avoid
- you need a simple, portable encryption library without native code
- your target platform is not Android
- you require AES specifically (deprecated in current versions)
- you need a permissively licensed dependency (license is non-standard)

## Facets
- artifact type: library
- maturity: active
- function: cryptography, security
- domain: security, mobile-development, android-tools
- platform: cpp, c
- tags: ndk, libsodium, chacha20, jni, anti-tampering, obfuscation, app-hardening, android
