How to Hash Passwords in Linux: A Comprehensive Guide
When it comes to cybersecurity, one of the most fundamental practices is properly securing passwords. In Linux systems, password hashing is a crucial aspect of protecting user credentials.
To hash passwords in Linux, follow these steps:
- Open a terminal window.
- Use the 'openssl' command with the 'passwd' option to generate a hashed password. For example:
echo -n 'yourpassword' | openssl dgst -sha256 - Copy the hashed password generated.
- Update the user's password in the Linux system with the hashed password.
By hashing passwords, sensitive information is transformed into an unreadable format, enhancing security. Remember, it is essential to use strong and unique passwords for each account.
