About Bcrypt Generator & Verifier
Bcrypt is a password-hashing function based on the Blowfish cipher. This tool allows you to safely generate bcrypt hashes with customizable cost factors (rounds) and verify plaintext passwords against existing hashes. All computations occur locally in your browser to maintain strict privacy.
Features
- Generate cryptographically secure bcrypt hashes locally
- Selectable salt rounds (cost factor) from 4 to 15
- Verify passwords against bcrypt hashes in real-time
- Copy generated hashes or populate the verifier with one click
- 100% local processing - zero server uploads
Frequently Asked Questions
What are bcrypt salt rounds?
The salt rounds (or cost factor) determine how many times the hashing algorithm is run. A higher value increases the computational cost, making it slower and much harder for attackers to brute-force, but also takes longer to compute.
