Generate and benchmark salted $2b$ Bcrypt password hashes with custom cost factors in-browser.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Type or generate the plaintext password to hash.
Adjust the work factor slider (rounds 4 to 14).
Click generate to create the salted $2b$ Bcrypt hash string.
Yes, hashing executes 100% in local client-side memory using Web Crypto APIs. No plaintext passwords or hashes are ever transmitted.
A cost factor of 10 or 12 is recommended for modern web applications to protect against offline GPU dictionary attacks.
