What does it mean when a password is encrypted?
Encryption simply means to translate the data into a secret code. To read that encrypted file, you need a decryption key to decipher the code. Encrypted data is referred to as cipher text which can only be decrypted using the correct key.
Where is the encrypted password of a user stored?
Most of the user account information is stored in the passwd file. However, password encryption and password aging is stored in the passwd file when using NIS or NIS+ and in the /etc/shadow file when using /etc files.
What is the difference between hidden and encrypted?
Steganography hides data inside other data, or, as some people have said, it hides data in plain sight. The goal is to hide the data in such a way that no one suspects there is a hidden message. It doesn’t actually encrypt the data, so it can’t be classified as either symmetric or asymmetric.
In which file the password are saved for each user?

Is it possible to change a password without re-encrypting it?
You can often change the password (or passphrase) without needing to re-encrypt whatever it is you’ve encrypted. The secret is simply this: your password wasn’t used to encrypt the disk. Something else was.
How is data encrypted without your password?
This encryption key is used to encrypt your data, not your password. In fact, your password hasn’t even been involved yet. That randomly-generated encryption key is itself then encrypted using your password (or some number based on your password). That encrypted encryption key is then stored somewhere — usually in your user profile on Windows.
Is it possible to change the encryption key?
The actual key used to decrypt your hard disk never changed. If you needed to change the encryption key used to actually encrypt your data, you would need to decrypt it completely and then re-encrypt. For example, you might turn BitLocker off and then back on again.
