MacOS: `sqlite3.DatabaseError: file is not a database`

[xanoni]

The below may help people who can't get Adhesive to run. I suspect it's related to the sqlcipher3 dependency , which appears problematic on MacOS.

Trying to get the credentials (fails)

$ python3 -m venv .venv
$ . .venv/bin/activate
$ python3 -m adhesive.signal_auth
Traceback (most recent call last):

    row = db.execute(query, *args).fetchone()

My workaround/solution

1. Open Signal's db.sqlite in sqlitebrowser, decrypt it with the hex-encoded password from config.json (make sure to select "raw" and to prefix the key with "0x"
2. Save the full db as plaintext.sqlite ... (alternatively, you can just extract the required credentials via sqlitebrowser and skip steps 3-4)
3. Patch adhesive/signal_auth.py to remove the decryption logic and point it at the plaintext db instead

 	_db.set(db)
 	return db

4. Run it again (works)
