Dump Wechat Messages from Android

WeChat(微信), as the most popular mobile IM app in China, failed to allow users to export well-formatted chat history. This tool can parse and dump WeChat chat history on a rooted android phone.

How to use:

Install Dependencies:

• python-PIL
• PyQuery
• pysox(https://pypi.python.org/pypi/pysox/0.3.6.alpha)
• python-csscompressor(optional)

Get Necessary Data:

• Get /data/data/com.tencent.mm/MicroMsg/long-long-name/EnMicroMsg.db from root filesystem, possible ways are:
  • ./android-interact.sh db
  • Use your rooted file system manager app
• Get WeChat user resource directory from your phone:
  • ./android-interact.sh res # you might need to specify a location if the default doesn't work
• Get Wechat uin, possible ways are:
  • ./android-interact.sh uin
  • Login to web wechat, get wxuin=1234567 from document.cookie

Run:

• Decrypt database, will produce decrypted_db.db (for now, Linux only):

./decrypt_db.sh <path to EnMicroMsg.db> <imei> <uin>

• Parse and dump text messages of every contact:

./dump_msg.py decrypted_db.db output_dir
