Bcrypt Generator
Hash and verify bcrypt passwords
How to Use
Enter password
Type the password you want to hash.
Set cost factor
Choose cost (10-12 recommended). Higher = slower but more secure.
Generate hash
Click Generate to create the bcrypt hash.
Verify (optional)
Enter a password and hash to verify if they match.
Frequently Asked Questions
What is bcrypt?
Bcrypt is a password hashing algorithm designed to be slow, making brute-force attacks impractical. It includes a salt automatically and has an adjustable cost factor.
What is the cost factor?
The cost factor (4-31) determines how computationally expensive hashing is. Each increment doubles the time. 10-12 is typical for passwords.
Why is bcrypt better than SHA-256 for passwords?
SHA-256 is fast (billions per second), making brute-force easy. Bcrypt is intentionally slow and includes built-in salting, making attacks impractical.
Can I verify a bcrypt hash?
Yes, paste a bcrypt hash and a password to check if they match. This is how login systems verify passwords.
Is my password data private?
Yes, all hashing and verification happens in your browser. Nothing is transmitted to any server.
