Why is bcrypt so secure?

The inclusion of a salt ensures that even if two users have the same password, their hashed values will differ due to the unique salt appended to each. This significantly complicates the task for attackers who aim to crack passwords through automated means.

Salting is a security measure employed to bolster the resilience of passwords against brute force and dictionary attacks. This technique involves appending a random string of characters, known as a salt, to the original password before hashing it.

bcrypt, a widely-used hashing algorithm, incorporates an additional layer of security by utilizing a 'cost factor.' This factor differentiates bcrypt from other hashing algorithms and serves as a metric to indicate the number of iterations performed on the password before generating the hash.

The cost factor plays a crucial role in determining the computational effort required to hash a password. A higher cost factor translates to more iterations, making the hashing process more time-consuming and resource-intensive for attackers.
