How resistant is that hardware to physical attackers and preventing PK extraction?
I feel like bitcoin hardware is the last place where you would want yo save a few bucks. I rather sell a few chairs and get a time tested device
Friendly periodic reminder that you don't need to spend a ton of currency on a hardware wallet.
A good USB (https://amzn.to/44tJrT4) + Tails OS (with Electrum pre-installed) is all you need.

application specific* time tested device
IDK but sha256 encryption is pretty good.
If you’re trying to guess a private key from a public key, but it’s different when you have control of the device and have to rely on the hardware to protect the secret. The old Trezors that lacked a secure element are a good example. It’s almost trivial to extract the PK from those if you know what you’re doing
