I vaguely remember some tool that was just a collection of random tools like that running as local server (including a bunch of crypto primitives) but I can't remember the name now...

You’re probably thinking of the tool made by GCHQ, CyberChef

Great tool that i'd recommend any software person, techy, reverse engineer etc should self-host.

I host in in my kube cluster with all outbound connections blocked, just to be safe.

Yup, thanks!
