This project is a collection of tools/information for hacking the Logitech Unifying protocol.

• python
• pycryptodome

Extract device information, including encryption keys, from a flash dump of a unifying receiver. A flash dump can obtained with the "nrf-research-firmware" and "nrf24-flash-dumper.py"

python tools/extract-devices.py flash_dump.bin devices.csv

Use device information, obtained from "extract-devices.py", to decrypt captured keystroke packets. Packets can be captured with the "nrf-research-firmware" and "nrf24-scanner.py" or "nrf24-sniffer.py".

python tools/decrypt-packets.py devices.csv packet_capture.txt > decrypted_packets.txt

Interpret decrypted keystroke packets, from a specific address, to generate an approximation of what was typed.
