About Bcrypt Generator

Securely generate bcrypt password hashes with configurable cost rounds and verify existing hashes.

Key Features

  • Adjustable cost factor (salt rounds) to balance speed against brute-force resistance.
  • Verify a plaintext password against an existing bcrypt hash, not just generate new ones.
  • Runs the bcryptjs implementation entirely in-browser โ€” your password never leaves the tab.
