How to Hash Password in Bash Script?

When it comes to cyber security, hashing passwords is a crucial step in protecting sensitive information. In a bash script, hashing passwords can be achieved using various methods for enhanced security. One common and recommended approach is to use the 'mkpasswd' command, which comes pre-installed in many Linux distributions. This command generates a hashed password using a chosen hashing algorithm, such as SHA-512.

To hash a password in a bash script using 'mkpasswd', you can run the following command:

hashed_pass=$(mkpasswd -m sha-512 your_password)

This command will generate a hashed version of 'your_password' using the SHA-512 algorithm. You can then store this hashed password securely in your script or a separate file for authentication purposes.

It is important to note that storing plaintext passwords in scripts or files is highly insecure and should always be avoided. Hashing passwords adds an extra layer of security by converting them into a unique string of characters that cannot be reversed to reveal the original password.

By incorporating password hashing techniques in bash scripts, you can better safeguard user credentials and minimize the risk of unauthorized access to sensitive data.
