Thank you!!
The Password Safe stores passwords in the STM32F1. These are additionally encrypted with an AES key, which is stored in a tamper-proof smart card (and is PIN-protected).
Does it mean that there is Another chip in Nitrokeys?
Where are they?? nitrokey-pro-hardware/Nitrokey_Pro_v2_schematics.pdf at master · Nitrokey/nitrokey-pro-hardware · GitHub
Do you mean any recent one? If so, I have not seen it. Could you link it here?
No. I’ve meant is the following. Has anyone tried to decap the chip and read its contents with a microscope or other way?
