Generate and verify bcrypt password hashes with custom salt rounds.
How to Use Bcrypt Hash Generator
Type the plaintext password you want to hash and choose the number of salt rounds.
Click "Generate Hash" to produce the bcrypt hash.
To verify, paste a plaintext password and an existing hash into the "Verify" section to check if they match.
Key Features & Practical Use Cases
Hashing test passwords with bcrypt to verify backend authentication logic during development.
Generating bcrypt hashes to seed a database with mock user accounts for testing.
Comparing a plaintext password against an existing bcrypt hash to debug login issues.
Frequently Asked Questions
What are "salt rounds" and which value should I use?
Salt rounds control how computationally expensive the hash is to compute — higher is more secure but slower; 10–12 rounds is a common, reasonable default for most applications.
Is bcrypt better than MD5/SHA-256 for passwords?
Yes — unlike fast general-purpose hashes like MD5/SHA-256, bcrypt is deliberately slow and includes built-in salting, which is specifically designed to resist password-cracking attacks.
Does hashing happen in my browser or on a server?
Entirely in your browser — your plaintext password is never transmitted anywhere while using this tool.
