Matrix and Riot support cross-signing now. Unfortunately the current support in Riot only offers the option to perform interactive verification. This does not work too well for people who only interact online and need to perform verification through another messaging system. It also does not support a TOFU model, a "certificate authority" or a web of trust approach.
This tool is intended to help with that. It is very much experimental and may cause cancer, set your computer on fire, require the sacrifice of your firstborn or cause mild indigestion. You have been warned.
