Bcrypt Hash Generator
Generate bcrypt password hashes with adjustable cost factor and salt rounds.
Enter a password above and generate a salted bcrypt hash you can store or compare against.
Uses bcryptjs, generating standard $2b$ bcrypt hashes compatible with any bcrypt implementation.
Bcrypt has been battle-tested since 1999, with mature, well-audited libraries in essentially every programming language, which makes it the conservative, safe default for a team that would rather rely on decades of scrutiny than adopt a newer algorithm early, even with Argon2 now the more modern recommendation. This tool generates bcrypt password hashes with an adjustable cost factor, where each increment doubles the computation time, and configurable salt rounds, a single straightforward tuning knob rather than the several separate parameters a newer algorithm exposes.

Useful for generating a bcrypt hash for a codebase that already relies on bcrypt everywhere else, tuning the cost factor higher to slow down brute-force attempts without switching to a different algorithm, or hashing a password with a well-established, widely supported library rather than adopting something newer.
