Frequently Asked Questions
Is it safe to generate or test passwords with this tool?
Yes. All salt generation, hashing, and verification run strictly in your browser memory via pure JavaScript (bcryptjs). No passwords or hashes are ever sent across a network.
What cost factor / round is recommended?
A cost factor of 10 to 12 is recommended for modern web applications, providing a good balance between hashing security against brute-force attacks and server latency.
Is my data uploaded when I use the Bcrypt Hash Generator & Verifier?
No. All processing runs entirely in your browser. Nothing is sent to a server unless you explicitly create a share link.
Does this tool work offline?
Yes. After the first visit, the PWA service worker can serve the page and run the formatter without a network connection.
What is the maximum input size?
Most tools accept up to about 5MB in the editor. Very large inputs are processed preferentially in a Web Worker and may download instead of filling the output pane.
