How to Hash a Password? A Simple Guide to Secure Password Protection

When it comes to protecting sensitive data online, one of the most crucial steps is securing passwords. One of the best methods to ensure password security is by hashing passwords.

What is Password Hashing?

Password hashing is the process of converting a password into a fixed-length string of characters using a mathematical algorithm. This irreversible process ensures that even if the hashed password is obtained by an unauthorized party, it cannot be easily converted back into the original password.

Steps to Hash a Password:

1. Choose a Secure Hashing Algorithm: Popular algorithms include SHA-256, bcrypt, and Argon2.
2. Generate a Random Salt: A salt is a random value added to the password before hashing to prevent the same passwords from producing the same hash.
3. Combine the Password and Salt: Concatenate the password and salt before hashing.
4. Hash the Combined String: Use the chosen hashing algorithm to create a fixed-length hash value.
5. Store the Hashed Password: Only store the hashed password in the database, not the original password.

By following these steps, you can securely hash passwords to protect user data from unauthorized access.
