Frequently Asked Questions

Is it safe to generate bcrypt hashes online?

With this tool, yes. Unlike other online hash generators, this one runs 100% in your browser. Your password never leaves your device — no network requests are made during hash generation.

What hashing algorithms are supported?

This tool supports Bcrypt (with automatic 10-round salt generation), SHA-1, SHA-256, and SHA-512. SHA hashes use the browser's native Web Crypto API for performance and security.

What is the difference between Bcrypt and SHA-256?

Bcrypt is specifically designed for password hashing — it's intentionally slow and includes a salt to resist brute-force attacks. SHA-256 is a fast, general-purpose hash used for checksums and data integrity. Use Bcrypt for passwords, SHA-256 for verification.

Can I use this to verify an existing hash?

This tool generates hashes but does not currently verify them. For Bcrypt verification, you would need to use bcrypt.compare() in your application code.

Does this hash generator work offline?

Yes. Once the page loads, all cryptographic operations run locally in your browser's memory. No internet connection is required for hash generation.
