Disk Lock (Fully Secured SHA-256) [For Both Types of Computers]

• Unbreakable/Crackable Encryption (EDIT: Bruteforce can crack if you used a idiotic/dumb password like 0000, so use strong ones)
• Good Security (Impossible to break in)
• Stable and Fast (But no GUI)
• Option for recover password (Create new disk, But you must know your password and computer id of the comp u want to recover, Those are listed when you are installing the Disk Lock)
• Can be easily integrated with your Operating System
• Bugfree?
• Safer Encryption [UPDATED]
• Works on both advanced and non advanced computers

• Updated the encryption system to a even safer one, Thanks to Anavrins again.
• Passwords are now salted and turned into HEX.
• Token changed (Delete DiskLock.shx before updating and reinstall from start cause you wont be able to recover disk with old and new version files mixing)

• Fixed a problem with normal computers where there was a color problem, I forgot to check for term.isColor() in both DiskLock and DiskRecovery files.
• Changed token and little security changes. (Delete DiskLock.shx before updating and reinstall from start cause you wont be able to recover disk with old and new version files mixing)
• Future plan to reset os.pullEvent is added, Now you can re-use CTRL + ALT + T after you logged in :)/>

• Make it possible to reset os.pullEvent back since the lock hooks it into pullEventRaw so nothing can be terminated ( You wont be able to test your programs but you can rename it to something else when testing or remove the pullEvent while testing :(/> )

6 Times Encrypts your key, Is that good?

function encrypt(str, salt)
  return pbkdf2(str, salt, 50) #-- Adjust 50 to your likings, higher the number, the slower the algorithm goes.
end

enc_pass = encrypt(pass, compId ..":" ..token)

Plus this app uses a special format for hashes

handle.write(enc_pass:toHex())

Introduction

This is a Disk Lock I was working on the last three hours, This is fully encrypted and safe means no one can break into your computer even with a startup disk! and can't install a virus, This might be the most secure lock ever

Updates

Update 1.1:

• Updated the encryption system to a even safer one, Thanks to Anavrins again.
• Passwords are now salted and turned into HEX.
• Token changed (Delete DiskLock.shx before updating and reinstall from start cause you wont be able to recover disk with old and new version files mixing)

Future Plans

• Make it possible to reset os.pullEvent back since the lock hooks it into pullEventRaw so nothing can be terminated ( You wont be able to test your programs but you can rename it to something else when testing or remove the pullEvent while testing :(/> )

FAQ

Q: OMG I lost my password you ******* bricked my computer, Now fix it or get reported.
A: First of all, Calm your ti** down, You can easily recover it if you know your computer ID and the password, If you cant remember it or are lazy as …., Then dont use this sorry. if you have your old computer id and password use the DiskRecover.lua file from any other computer or turtle, or better pastebin run azbTsxRc it, Then fill out things such as computer id and your password, Don't forget to insert a disk in the drive, Then after inserting your password will be delivered to that disk.
Q: How is this secure? I wont use this until I get my answer..
A: This is more secure than your house safe, Since it encrypts the key of the key of the key that it is impossible to break unless he knows your computer id and password, If you tell someone, better change it by reinstalling e.g., delete the DiskLock.shx in your root directory and then start the app, Plus this app uses a special format for hashes, But the hacker wont be able to break in unless he knows the both things (CompID and Password), The format is:
computerId:Token:Password
You can make this ultimately secure too!
Q: How to make this ultimately secure?
A: Before installing, Go to the startup or DiskLock.lua (whatever u downloaded it as) and then edit token, e.g. change characters but keep the size same and Make sure to save the token in the notepad with your computer id and password, When recovering using the diskrecover.lua, Don't forget to edit the token to the one you used to install and never change the tokens before deleting the DiskLock.shx cause you wont be able to read file if you changed token while the DiskLock data encrypted files were made with the old token, The app wont work!
Q: How do I make this work on startup? You just said that this is unable to break-in!
A: Its some common-sense, In the pastebin file it is written to save the file as startup, But you don't bother looking into it, Just rename the file to startup and done, The installer is the same as the login so this is all in one file except the recovery.
Q: Should I delete the DiskLock.shx in my root directory and DiskLock.shc in my disk? They seem useless…
A: No!!! Never do it, If the DiskLock.shc is deleted and DiskLock.shx is still there then you wont be able to log in unless you recover the password and put it in the disk using the DiskRecover.lua, But leaving this, If you delete only DiskLock.shx then your password will delete too, You wont have the Disk password anymore and you will be prompted to install or not whenever you run the Disklock, DiskLock.shx delete means removing password but not the app..
Since DiskLock.shx is checked to login with a disk or not..
Q: Should I give my disk to my friend? I want him to access my computer.
A: Don't unless you know what you are doing, If he changes the password(by using the diskrecovery.lua and changing the computer password of Disklock.shx, Ur doomed),
Don't let anyone access your pórçó-díó(porco dio) security..

DiskLock.lua (Rename to startup)

DiskRecover.lua (Recovery app, just run or use pastebin run)
