Hello. I am looking for a library to decrypt my electric energy meter's data. I found some code for Arduino, but it uses/includes AESh and GCM.h. In addition, I am using only Microchip PIC controllers + mikroPascal PRO for PIC, so what I found is almost useless to me.
I foind a "Crypto library", but this poor package manager is not installing it properly, nor do I know if this library is correctly working at all (the author doesn't respond and his last login here was 10 years ago).
If somebody could help, please?
The Energy Meter is LANDIS & GYR E450, It sends out one data block every 5 seconds through its User interface (M-BUS). I already built an electric interface module (converter to TTL serial level), but I stuck with decryption.
Thank you.
