Bcrypt Generator — Free Online Bcrypt Hash Generator

Storing passwords securely is one of the most critical responsibilities in application security. Using a general-purpose hash like MD5 or SHA-256 for passwords is insufficient because these algorithms are designed to be fast — and fast hashing benefits attackers brute-forcing stolen hash databases.

Bcrypt was designed specifically for password hashing. It incorporates a salt(random data mixed into each hash) to prevent rainbow table attacks, and a cost factorthat controls computation time. As hardware improves, you can increase the cost factor to keep hashing slow enough to resist brute force.

A bcrypt hash looks like: $2b$10$N9qo8uLOickgx2ZMRZoMyeIjZAgcfl7p92ldGxad68LJZdL17lhWyThe $2b$ is the algorithm version, $10$ is the cost factor, and the rest is the salt + hash.
