📖 How to Use Bcrypt Locker (Step by Step)

Step 1: Enter the password or secret in the left panel (Generate Hash).
Step 2: Choose the cost factor (salt rounds). Higher = more secure but slower.
Step 3: Click "Generate Bcrypt Hash" – a salted bcrypt hash is created (starts with $2a$).
Step 4: To verify, paste the hash into the right panel and enter the plain password.
Step 5: Click "Verify Password" – the tool confirms if the password matches the hash.

💡 Why Use Bcrypt?

✔️ Bcrypt is an adaptive cryptographic hash function designed for password hashing.
✔️ Includes a random salt and a cost factor (iterations) to resist brute‑force attacks.
✔️ All operations happen locally in your browser – your passwords never leave your device.

💡 Pro Tip: Use a cost factor of 10‑12 for production systems. Higher values (14+) may be too slow on older hardware. The hash includes the salt and cost, making verification easy.

🔒 100% client‑side • Your passwords never uploaded • Bcrypt RFC compliant • Zero tracking
