PyWxDump is a data recovery and export utility designed to extract, decrypt, and convert proprietary mobile messaging databases into readable formats for archival and recovery. It specifically functions as a tool to read and parse encrypted SQLite databases used by WeChat to retrieve chat history and user data.
The project focuses on the preservation of conversation history and the forensic recovery of application data for archival or legal purposes. It enables the conversion of proprietary message stores into portable, open formats to prevent data loss from account deletion or device migration.
The tool's capabilities include AES-cipher decryption based on device and account identifiers, protocol-buffer parsing for binary data, and the mapping of relational database structures into JSON or CSV files. It utilizes memory-mapped file access to handle large encrypted databases during the extraction process.
