What is Bcrypt and Why Use It?

Bcrypt is a password-hashing function designed specifically to be slow and computationally expensive. Unlike MD5 or SHA-256 (which are fast and vulnerable to brute-force attacks), Bcrypt includes a "Cost Factor" (Salt Rounds) that dictates how long it takes to calculate the hash.

• Built-in Salting: Bcrypt automatically generates and incorporates a unique cryptographic "salt" into every hash. This means hashing the exact same password twice will yield two completely different hashes, protecting against Rainbow Table attacks.
• Cost Factor (Salt Rounds): The cost factor dictates key stretching. A cost of 10 means $2^{10}$ iterations. A cost of 12 takes 4 times longer than 10. As hardware gets faster, developers can simply increase the cost factor to keep passwords secure.
• Hash Format: A standard Bcrypt hash looks like $2a$10$vI8aWB.... The $2a$ identifies the algorithm version, 10$ is the cost factor, followed by the 22-character salt and the 31-character hash.
• 100% Client-Side Processing: Our generator utilizes bcrypt.js to compute hashes asynchronously entirely inside your browser. Your plain-text passwords are never sent over the internet or logged in a database.
