What Is Password Hashing and Salting?

With cyber threats on the rise, more advanced ways have to be learned to make sure that data on passwords is secure. On this ground come two major methods of making passwords as secure as possible: hashing and salting. These two processes are geared toward ensuring that passwords remain safe from unauthorized access and possible breaches. Now, let’s get into what these terms are and why they would be of great importance for strong security.

What Is Password Hashing?

Password hashing is the process of changing clear text passwords into an unchangeable string of characters—usually an alphanumeric mishmash without any fixed length. It is done with a particular hashing algorithm, namely SHA-256 or Bcrypt. The difference between encryption and hashing is that hashing is only a one-way function; therefore, one can’t retrieve the original password by reversing the hash. What is stored in the system is the hashed value. During the log-in process, the system hashes the input password and compares the hash to that of the stored one to guarantee it is genuine. This way, even if attackers get hold of the stored hashes, they still cannot easily decipher the original passwords.

Why Hashing Is Essential?

Hashing is at the center of the integrity of a system; in other words, it is about how password security is achieved. By hashing passwords, even if attackers manage to breach the database, they will only find hashed values. That are quite difficult to reverse-engineer. In this way, the method greatly minimizes the risk of exposing user credentials.

Further, modern-day hashing algorithms such as Bcrypt have features such as key stretching built into them that make it time-consuming for an attacker to compute hashes for the same input. This additional complexity secures the passwords even further against brute-force attacks, hence hashing is the mainstay of all modern cybersecurity strategies.

Password Salting

Salting constitutes an extra layer of security that is applied to passwords before hash. A salt is nothing but a unique, random value that is appended to each password before it is hashed. This hash will contain this “random” value, making it different even when two users employ an identical password to create it. A salt helps protect against pre-computed attacks, such as rainbow table attacks that use extensive databases of hashed values in order to quickly crack passwords. Since the salt is unique for each password, it ensures that each password hash is unique and makes cracking many times harder if the attackers want to use precomputed tables to crack into accounts.

Advantages of Salting

One of the major security increases salt provides over password hashing alone is that it makes pre-computed attacks not viable. If two identical passwords were hashed without any salting, they would still return the same hash, leaving them vulnerable to precomputed attacks. As such, salting will ensure that even if there are two users with the same password, the hashed passwords of both users will be different. This stops the attacker dead in their tracks from trying to exploit the patterns.

Salting also complicates the brute-forcing process because there is more data to process for an attacker. It makes the hash unique and complex, therefore a better defense against the most typical hacking schemes, leading to better protection of credentials.

Action of Hashing and Salting in Modern Systems

Hashing and salting are put to use in modern password management systems. Techniques ensure not only secure storage of user passwords but also their resistance to various attack methods upon realization of password managers. As one example, all the white-label password manager solutions of PureWL have utilized advanced techniques for hashing and salting to keep user data safe. Through such features used in its products, PureWL helps businesses offer a secure experience to their clients or employees, keeping sensitive information away from potential threats.

Conclusion

Understanding password hashing and salting is crucial for anyone concerned with digital security. All of these techniques combined are used to keep unauthorized users and potential breachers at bay. For businesses looking to boost the security provisions they have in place, taking advantage of a password manager that uses techniques similar to those provided by PureWL will provide significant improvements in those protections. This is because it is through the application of hashing and salting during password management that there will be strong security of the user data such that attacks will be harder to mount, therefore leading to a safe online environment for everyone.
