Bcrypt Hash Generator & Verifier
Generate secure bcrypt hashes and verify plaintext passwords. Runs 100% in your browser.
About Bcrypt Hashing
Bcrypt is a widely trusted, adaptive password hashing function designed to remain resilient against brute-force attacks over time. Unlike fast hashing algorithms like MD5 or SHA-256, bcrypt intentionally introduces a computational cost factor (called "salt rounds" or the "work factor"). This means that as hardware gets faster, you can increase the number of rounds to make brute-force attacks infeasible. It is the industry-standard choice for storing user passwords in virtually every major web framework.
This tool runs entirely within your browser using WebAssembly, meaning your plaintext password is never sent to any server. It is safe to use with any real or test credentials.
How to Use This Tool
- Enter Password: Enter the plaintext password you wish to hash in the input field.
- Adjust Salt Rounds: Use the slider to set the cost factor (10-12 is typically recommended for production). Higher values are more secure but slower to compute.
- Generate Hash: Click "Generate" and the bcrypt hash will appear in the output field. Copy it to store in your database.
- Verify a Hash: Scroll down to the verification panel, enter a plaintext password and any bcrypt hash, then click "Verify" to instantly see if they match.
