I went to the page Brute-Forcing the PIN for a Catalyst QR Code Project Catalyst
I managed to scan my QR code using @maslick/koder
I was unable to figure out how to use pbkdf2 and chacha-js for the derivation and decryption. They aren’t web apps. They’re javascript code. Entering them on the command line (I’m running Windows 11) returned an error message that they aren’t commands, programs, or batch files.
