---

This tool generates thumbnails for CFG of functions from binary files.

It takes all function of a binary executable and generates their CFG in 10x10cm in .PNG format. It is based on radare2 and Graphviz.

Installation

The installation is really simple, with few dependencies:

apt install radare2 graphviz imagemagick

Usage

To graph all functions' CFG:

./bincfg.sh -n BINARY_PATH -F

Thumbnails will be saved in ./BINARY_PATH_CFG/.

---

Others features:

./bincfg.sh -h # Display the help
./bincfg.sh -n BINARY_PATH -c # Graph the global CFG of the binary
./bincfg.sh -n BINARY_PATH -l # List all functions of the binary
./bincfg.sh -n BINARY_PATH -f function_name # Graph the CFG of a specific function
