I was thinking about having an encrypted USB flash memory where I would store some passwords and that kind of information. I want it to be encrypted just in case I lose it and someone finds it.
I was wondering if it's possible to "encrypt" using public keys like in SSH. I don't know if it would be called encryption but the idea would be that the only way to access to the files in the USB is having the key in your computer (just like as in SSH).
In case that's not possible, encrypting a single file with the same idea, would do it.
