Encryption

So I was wondering how I can encrypt a hard drive and use my phone or a flash drive and use that as a "key". Basically thinking of the computer as a door and the usb/phone as the key.

I think encrypting your hard drive would slow down your computer and what about if you lost your phone?

There are various programs that allow you to encrypt a harddrive but if you are looking for the more diy answer.

 

There are two primary types of encryption Symmetrical and Asymettrical cryptography. Symetrical uses one  key to encryp and decrypt,  Asymetical uses two.

Here is some  background:

If you want to wrote your own encryption program I would reccomend using the Microsoft cryptography libraries.

If you want a more in depth example here is a link to my github repo that has a encryption program that I have been working on:
