Is encryption that simple? It shouldn’t be, and each company’s encryption method is different, even multi-layered, so it’s not that easy to encrypt.

This is cracked, so easy

So does it mean that it won't be so easy to be discovered if we read the ID indirectly?

If the Flash is encrypted, can it still be cracked this way?

It's very easy, stm32f103 cracking costs only a few hundred dollars

Deliberately hiding the crack is much more difficult, otherwise it will be broken without disassembly

No matter how many layers there are or how complex the algorithm is, it can be cracked, so the key is to make it impossible for people to find the place to read the ID.

It seems that money can get you anything.

It is much more difficult to crack if it is deliberately hidden, otherwise it will be cracked without disassembly

Then I think using uid encryption is still risky.
