How Does Individual File Encryption Work?

Ever wanted to encrypt and secure individual files without having to encrypt your entire hard drive or SSD? Here's how to do it, along with an explanation on how individual file encryption works.

Linus is by far the most hardworking youtuber I know, I really appreciate his whole team and Linus himself for producing so much of good contents. Thank you for the hard work you guys do.

Hold on. Is that a 4GB Flash drive? Is this 2008?

Wow, it has been a long time since your transition to the ad was so seamless... Nice!

This is a acceptable form of sponsoring video's. Thank you linus for seperating ad from info!

No mention of encryption of individual files via winrar/7zip? Much easier than most 3rd party applications

It's amazing how far technology has come... To hide porn.

I am just saying linus, this video is used by my college to explain file encryption!

Probably should have mentioned that with EFS if you reset or change your Windows password outside of the standard change password option while logged in, such as from another user account or with 3rd party boot media, or delete and recreate your account or reinstall Windows, your files are lost and can't be decrypted.

If you are on a domain, the EFS recovery policy is controlled by the group policy assigned by the Domain Admin security group. EFS assigns the local Administrator user account or the domain Administrator user account as the recovery agent by default. Your EFS encrypted files are not protected from the company on your work computer.

I've got a video suggestion: Fullscreen! I'm curious as to how fullscreen differs in handling from windowed mode, as well as what all that flickering and re-sizing is when you start a fullscreen program or alt-tab between one (most notable on multi-monitor setups or when the resolution setting is different from the monitor's native).

Very informative and clear cut video as always.

I think this is the kind of encryption Google started using on latest version of Android.

Keep up the good work.

Forget hardware level encryption, we need Linus level encryption.

This video has the best transmission into a sponsor part of the video.

Beginning of video: windows passwords are easy to get around
Middle of video: use encryption that ties to your windows password login.

Best method I've found is creating a .VHDX (virtual drive), mount it, put your files in, then encrypt that .VHDX with bitlocker.

[klugeskind]

I just .zip it with a strong password.

[blehhhhhhish]

Relevant sponsor is relevant (And actually pretty cool) - keep up the good work!

Thank you it did help my student understanding in less than 10 minutes

multiple +12V rails on one power supply explained would be very helpful right now!

If someone has a full drive encrypted and the Windows PC is locked, there is virtually no way to access the files on the PC unless someone cold-boots the RAM and gets the key.

This is of course, using an up-to-date Windows install on which you can't ask Cortana to unlock the PC.

So using the EFS encryption is redundant as the encryption is transparent with the Windows session, as you said.
