Protect your user credentials with strong cryptographic security. The Bcrypt Hash Generator & Verifier is a free online tool that helps you securely hash strings (like passwords) using the Bcrypt algorithm, and also verify if a plain password matches a previously hashed value.
This tool is perfect for developers, security engineers, and web admins who want to safely encode passwords without installing any software.
Our simple web interface lets you hash and verify in seconds.
✏️ Enter your password or string
🔐 Set the cost (rounds) — default is 10 (recommended)
⚡ Click “Generate Hash”
📋 Copy the Bcrypt hash for storage in your database
🔑 Enter the plain password
🔄 Paste the previously saved Bcrypt hash
✅ Click “Verify”
🟢 Get an instant result — match or no match
✅ Real-time Bcrypt hashing
✅ Password-to-hash and hash verification
✅ Adjustable cost factor (strength)
✅ No data stored or logged
✅ Works client-side (privacy-first)
✅ Free, fast, and easy to use
Bcrypt is a secure password hashing algorithm designed to be slow and resistant to brute-force attacks. It is widely used in modern authentication systems.
Yes, everything runs in your browser (client-side). No passwords or hashes are sent to the server.
The cost (or rounds) determines the complexity of the hash. A higher value means more CPU time is needed to hash/verify, making brute-force attacks harder.
You can test and generate production-level hashes, but make sure your backend system is also configured to verify Bcrypt using secure libraries.
Yes, store the generated Bcrypt hash in your database. You can use it later to verify login attempts.
Bcrypt is available in almost every modern programming language: PHP (Laravel), Node.js, Python, Ruby, Java, Go, C#, etc.
