Answer 1

The question is so complex that there is no single answer.
If it’s right according to your text, a flash drive with hardware encryption and a password like this is probably suitable - https://habrahabr.ru/company/acelab/blog/256287/
You can store keys on it, access to it without knowing the pin code is impossible, the data will be destroyed when the password is guessed.
