Bcrypt Hash Generator & Verifier
Generate and verify bcrypt password hashes
How to Use Bcrypt Hash Generator & Verifier
- 1Enter a password and choose the cost factor (rounds). Higher rounds = more secure but slower.
- 2Click "Generate Hash" to create a bcrypt hash.
- 3Switch to "Verify Hash" mode to check if a password matches an existing hash.
About Bcrypt Hash Generator & Verifier
Generate bcrypt password hashes with configurable cost factor (salt rounds). Verify passwords against existing bcrypt hashes. Bcrypt is the industry-standard adaptive hashing algorithm for secure password storage. All processing happens in your browser.
Frequently Asked Questions
What is bcrypt?
Bcrypt is a password hashing algorithm designed to be slow and computationally expensive, making it resistant to brute-force attacks. It automatically generates a salt and embeds it in the hash output.
What cost factor should I use?
The default of 10 is suitable for most applications. Each increment doubles the computation time. Use 12+ for high-security applications. Above 14 can cause noticeable delays.
Why is bcrypt better than MD5 or SHA-256 for passwords?
MD5 and SHA are fast hashes designed for data integrity, not password storage. Bcrypt is intentionally slow and includes a built-in salt, making it much harder to crack via brute force or rainbow tables.
Is my password sent to a server?
No. All hashing and verification is performed locally in your browser using the bcryptjs library. Your password never leaves your device.
