Hi Sara and thanks for the speedy reply! Indeed, timers are the main issue. I manged to get v1.1.0 to work now. The only issue there was that __AVR__ is...

One year later... Maybe it's time to make the key public? 0x7b, 0xca, 0x59, 0x6f, 0x22, 0x73, 0xc5, 0x19, 0x5e, 0x41, 0x42, 0xaa, 0x3d, 0x20, 0x1e, 0x25

That question is best answered by fully reading this amazing repository ;)

The signature verification issue can be bypassed by not specifying the PRAK key, adding the -f option to force decrypt, and using -k UFIE-2022-08.
