Bcrypt Generator & Verifier

Hash passwords with bcrypt and verify existing hashes, choose a cost factor that balances security and speed.

About bcrypt

Bcrypt is the industry-standard algorithm for storing passwords. Unlike raw SHA or MD5, it is intentionally slow, the cost factor sets the number of iterations as 2cost, making brute-force attacks prohibitively expensive. A cost of 12 requires roughly 250 ms per hash on modern hardware, which is imperceptible to users but devastating for attackers. The hash embeds the cost and salt, so no extra columns are needed. This tool uses server-side bcrypt and does not retain your input.
