Bcrypt Password Hash Generator

Bcrypt is a password hashing function based on the Blowfish cipher. It is designed to be computationally expensive and includes a built-in salt, making brute-force and rainbow table attacks impractical. It remains the industry standard for secure password storage alongside Argon2.

The cost factor (also called work factor or rounds) controls how computationally intensive the hashing is. Each increment doubles the work required. A cost of 10 means 2^10 = 1024 iterations. Higher values mean better security against brute-force attacks but slower hash generation. A cost of 10-12 is typical for production.

No. Bcrypt is a one-way hashing function - it cannot be reversed. To verify a password, you hash the input again and compare it to the stored hash. This is why bcrypt is ideal for password storage.

This tool runs entirely in your browser - no data is sent to any server. It implements standard bcrypt with a random salt. However, for production password management, use a dedicated password manager or your application's built-in bcrypt library.
