A cross-browser testing tool that can be used to encode bcrypt keys is useful. You can use this utility to generate many valid bcrypt password hashes if you are writing tests that include hashed passwords. If you require a strong adaptive password, the iteration count can be increased. The slower bcrypt works, the more rounds there are. This property of bcrypt can be used in order to generate extremely slow test cases, which can cause denial of service attacks or resource exhaustion attacks.

What is Password Hashing, exactly?

Password is a one-way method of securing plaintext passwords. It involves creating a bit string of a fixed length called hash using cryptographic's hash function. A cryptographic hash function designed to be one-way, meaning that it cannot be reversed, is called a cryptographic hash function.

What is Password Hashing Competition, you ask?

Password Hashing Competition organized by cryptography, and security experts is an open contest to This site cannot be reached. To raise awareness of the need for a strong password hashing algorithm and to identify the hash function that can be recognized and used as a recommended standard, Bcrypt was named the final PHC recipient on 20/07/15.

What is Bcrypt and how can it be used?

It is a cryptographic hashing algorithm, which is highly recommended for password hashing.
Enter the plain text to be encrypted using bcrypt. It can be any text. Now choose the salt circle. The salt round is the cost factor.
The same applies to matching a hashed username. To do so, enter both the hashed and plain text passwords. After comparing the inputs, the tool will determine if the hashed and plain text match or not.
There is a difference between Hasheds that start with 2y and others that start with 2a. These are two versions of BCrypt. Due to improvements over time some older implementations may not work with newer ones. So I had to use an older implementation of 2a along with 4 rounds to replace a hash in my DB so I could access other sites that use 2y.
It is ideal to replace the older implementation with a newer version and add more rounds as time goes on. This can be accomplished by re-hashing your user's plain text password at their next login. You can also do a string test on the first 6 characters (or split it by $ to look at the first two indices).
