The list of all passwords is kept within the operating system. Thus, if a user manages to read this list, password protection is no longer provided. Suggest a scheme that will avoid this problem. (Hint: Use different internal and external representations.)

The saved password in the operating system can be protected by the encryption method that can only be assessed by the person who knows the decryption method.

What are encryption and decryption?

Encryption and decryption is a protection method that allows the safety of the passwords, texts, images, and videos from the third party or hackers.

The passwords can be protected if they are in encrypted formats where the codes are only known by the developer or the owner of the content. The readable letters and messages are converted into codes that are unreadable in the encrypted format.

When the person with the authority converts this unreadable into readable form then it is called decryption. Hence it protects the passwords from external access.

Therefore, the encrypted codes can be used to protect the passwords.
