Linux Configuration File Read Only by Root and Contains Encrypted User Passwords

In the Linux operating system, the file that can only be read by the root user and contains users' encrypted passwords is the /etc/shadow file.

The /etc/shadow file is a crucial system file that stores user account information, including usernames, encrypted passwords, and password-related information like password expiration dates and minimum password age.

It is essential for the security of user accounts that the /etc/shadow file is protected and only accessible to the root user. Unauthorized access to this file can lead to a breach of user privacy and compromise the security of the system.
