Why bcrypt?
Bcrypt is designed to be slow and computationally expensive, making brute-force attacks impractical. Unlike MD5 or SHA256, it's purpose-built for passwords.
What is the cost factor?
The cost factor (rounds) determines how many iterations (2^rounds) are performed. Each +1 doubles the time. Round 10 = 1024 iterations, Round 12 = 4096 iterations.
Salting
Bcrypt automatically generates a random salt for each hash. This means the same password produces a different hash every time, preventing rainbow table attacks.
