I've been using the tool called CC by Aleph for ages now. To my own surprise, having found this tool on some forum, the tools remains largely undiscovered even by the cryptography/reverse engineering standards.
It seems the development for it had become slow/stopped in 2016. I wonder, how well does this tool stand against better known open-source tools such as BinWalk? I consider trying to rewrite the tool on Python, and I wonder if this is worth the while.
