The tool does things that I missed in other tools, mainly it’s: cross-platform - CLI tool written in Rust, extensible - adding a new language is just a matter of adding a config file, and capable - full UTF-8 support, built-in IoC calculator and the list goes on.

In the process I’ve written a Kaitai Struct definition of the long-forgotten DIME format and contributed it to the Kaitai Struct formats repo. Read more...
