# tuya-mobile: a Python reconstruction of Tuya app signing and API calls

> tuya-mobile reconstructs Tuya mobile-app request signing, encrypted API calls and MQTT signaling credential derivation in Python. It replaces the app's native libthing_security.so signing step with HMAC-SHA256, SHA256 and MD5 calculations and includes versioned Smart Life and Tuya Smart profiles.
