Password Hashing

What is Password Hashing?

Password hashing is a security practice where a mathematical algorithm converts a plain-text password into a fixed-length string of characters. This process is one-way, meaning the original password cannot be easily recovered from the resulting hash, protecting user credentials even if a database is compromised.

Why It Matters

• It ensures that even if an attacker gains access to a user database, they cannot see the actual passwords of the users.

• Using strong hashing algorithms with unique salts prevents attackers from using precomputed tables to crack passwords.

• It is a fundamental requirement for secure authentication systems and is mandated by various data protection regulations.
