As my current 2 projects are coming to a close I am looking at something different. I was thinking about a finger print access system. I have found a project that is perfect but it uses a plain text password to ID the finger print (initial set up). It can store multiple finger prints so different people can operate it.
Is it possible to encrypt passwords on an Arduino?
Of course it is. What scheme do you want to use?

Good question. Nothing extraordinary. I don't know whats available for an arduino. 128bit maybe.
Google "arduino encryption library" for several. Most popular schemes have been implemented.

My first question would be why? What problem are you trying to solve by doing this?

He said it in his first post pretty clearly.

And, why is that a "problem" that needs "solving"?

... Because storing passwords in plain text is never a good idea when it comes to security, no matter how mundane?
That aside, OP's problem is that they want to keep passwords "securely", for whatever reason. Maybe the server is on a shared computer, maybe on a shared network, maybe the rig is connected to internet, who knows.
Why are we even talking about this? This is utterly pointless. When I ask my mom how to cook rice without screwing up she doesn't go "but why is that a problem that needs solving?"
