CRET - Can Bus Reverse Engineering Toolkit
Author: Adrian Marcos Batlle
Why another CAN tool?
- Built from scratch with new ideas for analysis mechanisms.
- The unique tool with easy identification and tagging of the packets.
- Comfortable analysis using a GUI.
- Internal project management with SQLite database.
- RAW Sniffing.
- Real-time graphical sniffing.
- Posibility to configure to ignore unuseful packets when sniffing.
- Posibility to split byte values to help identification of the data.
- JSON import and export for identified packets.
Setup and running:
- Just run .jar file. Custom hardware is needed. You can find gerber files in hardware folder to DIY.
Features
- 2-Interface support at the same time.
- RAW sniffing on trace mode (shows all packet changes).
- RAW sniffing on monitor mode (updates all packet changes).
- Real-time graphical sniffing.
- Remove option to hide unuseful plotted packets.
- Internal project management with SQLite database.
- Dashboard with identified packets.
- Posibility to import and export JSON files with the identified packets.
- Posibility to ignore unuseful packets (packets with value 00).
- Posibility to split bytes to help identification of the data.
- Threaded sniffing and GUI.
- Clean tabs option for each analysis.
- Comfortable and intuitive GUI.

Questions
What parts does the CRET use?
85 parts, built around the MCP2551-I/P, GL850G and SY6280AAC. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the CRET KiCad files?
From the ms02-1337/CRET repository on GitHub, at the commit this page was made from: the board is hardware/scheme/cret.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CRET design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
