Hello, I’m currently working on my Final Year Project which is Password-Based Folder Lock System. I need assistance in understanding encryption and decryption method. There are several method that I have encounter which is AES, DES and RSA.

My question is, how do does the encryption method manage to lock a folder and make the folder can’t be opened without a password and if the locked folder is deleted and undo, the folder is still locked. If the locked folder is copy and paste , the folder is still locked.

I can come up with this question because I have found a similar project with me, but I don’t know/understand how to ‘lock’ the folder.

Any help is highly appreciated!
