Where are encrypted passwords stored in Linux?
Password hashes were traditionally stored in /etc/passwd , but modern systems keep the passwords in a separate file from the public user database. Linux uses /etc/shadow . You can put passwords in /etc/passwd (it’s still supported for backward compatibility), but you have to reconfigure the system to do that.

How to Generate/Encrypt/Decrypt Random Passwords in Linux
- Generate a random unique password of length equal to 10 characters using command ‘pwgen’.
- You may use ‘makepasswd’ to generate random, unique password of given length as per choice.
- Encrypt a password using crypt along with salt.
Which file contains encrypted password information for groups?
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.

How are UNIX passwords encrypted?
UNIX password encryption uses the DES algorithm 25 times in a row. The first DES round uses 64 0-bits as input and encrypts them with the password the user inputs, with a permutation taking place during the encryption process. There are 4096 possible permutations. The permutation used is randomly chosen for each user.
Which file contains user account information?
