About Bcrypt Hash Generator & Verifier
The Bcrypt Hash Generator & Verifier is a professional security tool that creates bcrypt password hashes and verifies passwords against existing bcrypt hashes. Bcrypt is an adaptive password hashing function that incorporates a salt and configurable cost factor (work factor) to protect against rainbow table attacks and ensure computational difficulty increases over time as hardware improves.
Why use a Bcrypt Hash Generator & Verifier?
Bcrypt is considered the gold standard for password hashing because it automatically handles salt generation and provides adjustable computational cost to counter evolving hardware capabilities. Unlike basic hash functions, bcrypt's adaptive nature means it remains secure against brute force attacks as computing power increases, making it the preferred choice for modern web applications and secure systems requiring robust password protection.
Who is it for?
Essential for web developers implementing user authentication systems, security engineers building secure applications, and backend developers managing user credentials. Perfect for full-stack developers working on login systems, DevSecOps teams establishing security standards, and anyone responsible for protecting user passwords in databases and applications.
How to use the tool
Enter the password you want to hash in the password input field
Select the desired cost factor (rounds) - higher values provide more security but require more computation time
Click generate to create a secure bcrypt hash with automatic salt generation
Copy the resulting bcrypt hash for storage in your database or application
For verification, enter both the original password and existing bcrypt hash to confirm they match
