signal-export

export signal messages to HTML or plain text. Has not been updated to recent signal database versions, PRs welcome.

prerequisites

• sqlcipher
• Signal desktop (the exporter tries to be smart about finding the encrypted database, if it fails, override with --signal-home)

exports by month

Signal chat logs can get very large, so you might want to split things up. There's a months.py helper for that. Example, exporting monthly starting from at 2018-06:

months.py 2018-06 --extra-fmt='--out=%s.html' --cmd='signal_messages.py --conversation 123-456-abc-def --format html' | while read -r line; do echo $line; $line; done

doxx

usage: signal-export.py [-h] [--conversation CONVERSATION]
