## What it is
A C++ command-line tool for working with backup files generated by the Signal Android app. It can decrypt, inspect, export, merge, crop, and repair Signal backups, including dumping databases/media and exporting conversations to HTML, TXT, CSV, and XML.

## Use cases
- export signal messages to html or csv
- decrypt signal android backup file
- merge two signal backups
- fix broken signal backup
- extract attachments from signal backup
- import telegram chat history into signal

## When to choose
- you need offline, scriptable access to Signal backup data
- you want to export or migrate Signal conversations to other formats or apps
- you need to repair or merge Signal backup files

## When to avoid
- you need a GUI tool
- you want to work with Signal Desktop data exclusively without Android backups
- you need guaranteed compatibility with the latest Signal format at all times, as format changes can temporarily break functionality
