Bcrypt Hash Generator
A reliable tool for generating and verifying bcrypt hashes, all processed securely within your browser.
Generate Hash
Input any text to generate a secure bcrypt hash. Higher rounds improve security but increase processing time.
High Strength: Recommended for production
Verify a Hash
Check if a plain-text string matches an existing bcrypt hash.
Frequently Asked Questions
What is Bcrypt?
Bcrypt is a robust password-hashing function that is deliberately slow to compute, making it highly resistant to brute-force attacks. It's a standard choice for securely storing user passwords.
What does the "Cost Factor" mean?
The cost factor (or rounds) determines how computationally intensive the hash calculation is. A higher number means more security and a slower process. A value of 12 is a widely accepted baseline for production systems.
Is this online tool secure to use?
Yes. All calculations are performed directly in your browser using the `bcryptjs` library. Your data is never sent to our servers, ensuring complete privacy and security.
Should I use this tool for my application?
This tool is excellent for learning, testing, or generating individual hashes. For a live application, you should always implement a trusted bcrypt library directly within your own backend code.
