Bcrypt Hash Generator
Generate and verify bcrypt password hashes
Input
Bcrypt Hash
BCrypt is a widely-used password hashing algorithm designed specifically to be slow (on purpose) to resist brute-force attacks, unlike general-purpose hashes like MD5 or SHA-256. This tool generates a BCrypt hash from a password and can verify whether a plain-text password matches an existing BCrypt hash.
Frequently asked questions
BCrypt is deliberately slow and includes a built-in salt, making it far more resistant to brute-force and rainbow-table attacks than fast general-purpose hashes like MD5/SHA-256, which were never designed for password storage.
No - BCrypt includes a random salt each time, so the same password produces a different hash output every time it's hashed. This is intentional and is what makes it resistant to precomputed rainbow-table attacks.
Hashing runs in your browser, but as a general precaution, avoid pasting real user passwords from production systems into any third-party tool - use sample/test passwords when just exploring how BCrypt works.
