Bcrypt hash is generated.
Salt rounds (also called the cost factor or work factor) determine how computationally expensive the hashing process is. Each increment doubles the computation time — 10 rounds takes about 100ms while 12 rounds takes about 400ms. Higher values make brute-force attacks much slower, providing better protection as hardware gets faster over time.
For most web applications, 10-12 salt rounds provide a good balance of security and performance. Use 12+ rounds for high-security applications like banking or admin accounts. The ideal value depends on your server's CPU capacity — the hash operation should take between 100ms and 500ms to remain practical for login flows while being slow enough to deter attackers.
Bcrypt is specifically designed for password hashing with three key advantages: built-in random salt generation (preventing rainbow table attacks), an adjustable cost factor (adapting to faster hardware), and intentionally slow computation (deterring brute-force attacks). SHA-256 is too fast for password hashing, allowing attackers to test billions of guesses per second.
