Storing passwords in plain text is unsafe. Bcrypt is a standard for password hashing with a built-in salt and adjustable cost. The Create Bcrypt Password tool generates bcrypt hashes from plain text with an adjustable cost factor so you can store passwords securely in applications—all hashing in your browser, no password sent to any server.
What is the bcrypt cost factor?
Cost (rounds) controls how slow hashing is. Higher values are more secure but slower; default 10 is a good balance. The tool accepts plain-text password and cost; it outputs a bcrypt hash you can store in your database or config. Bcrypt is designed for password hashing with a built-in salt and is widely used in production. No password is sent to any server. Use it to hash passwords for app storage, API secrets, or any system that expects bcrypt hashes—and verify with the bcrypt verifier tool. Bcrypt is intentionally slow to resist brute force; increase cost only if you accept longer login times (typical cost is 10–12).
Key Features
- Cost factor — Cost (rounds) controls slowness. Higher = more secure but slower. Default 10 is a good balance.
- Security — Bcrypt is designed for password hashing with built-in salt. Widely used in production.
- Privacy — No. Hashing runs in your browser. Your password never leaves your device.
- Input — Enter plain-text password and set cost (rounds). Copy generated hash to store in database or config.
- When to use — Hash passwords for app storage, API secrets, or systems that expect bcrypt. Verify with bcrypt verifier tool.
- Slow hashing — Bcrypt is intentionally slow to resist brute force. Typical cost 10–12; increase only if you accept longer login times.
How to Use Create Bcrypt Password
- Open the Create Bcrypt Password tool.
- Enter plain-text password. Set cost (rounds). Copy the generated hash.
- Store hash in your app or database. Verify with Verify Bcrypt Password. Use the "Use tool" button on the docs page if you are reading this from the documentation.
Real Use Cases
- App passwords — Hash user passwords before storing. Use with Verify Bcrypt Password, Scrypt Generator, and Password Generator. Use with Hash Generator for non-password hashing.
- API secrets — Store hashed secrets. Verify on login or API key check. Use with Bcrypt Verifier.
- Development — Generate hash for local DB or tests. Use with Scrypt Generator if your stack uses scrypt.
- Documentation — Show team how to generate bcrypt. Use output as reference.
- Migration — Move from plain text or weak hash to bcrypt. Generate new hashes; verify with Bcrypt Verifier.
- Cost tuning — Increase cost for higher security; keep login time acceptable. Use verifier to confirm hashes still verify.
Why Use Create Bcrypt Password Instead of Alternatives?
- vs. Verify Bcrypt Password — Verify Bcrypt Password checks password against hash. This tool generates hash. Use both: generate then verify.
- vs. Scrypt Generator — Scrypt Generator produces scrypt hashes. Choose based on stack; both are secure. Use bcrypt when your app expects bcrypt.
- vs. Password Generator — Password Generator generates random passwords. This tool hashes a password. Use generator for new password, then hash with this tool.
- vs. Hash Generator — Hash Generator is for generic hashes (e.g. SHA-256). Bcrypt is for passwords. Use bcrypt for passwords.
Benefits for Developers
- Developers — One place to generate bcrypt for apps. Adjustable cost. No server; verify with bcrypt verifier.
Common Mistakes
- Hashing slow — Bcrypt is intentionally slow. Increase cost only if you accept longer login times; typical cost is 10–12.
- Expecting verification — This tool only generates. Use Bcrypt Verifier to check password vs hash.
- Wrong cost — Too low = weaker; too high = slow logins. Default 10 is a good start.
- Forgetting to copy — Copy the hash before closing the tab.
Frequently Asked Questions
What is the bcrypt cost factor?
Cost (rounds) controls how slow hashing is. Higher values are more secure but slower. Default 10 is a good balance.
Is bcrypt secure?
Yes. Bcrypt is designed for password hashing with a built-in salt and is widely used in production applications.
Is my password sent to a server?
No. Hashing runs in your browser. Your password never leaves your device.
Enter the plain-text password and set the cost (rounds). Copy the generated hash to store in your database or config.
When should I use a bcrypt generator?
Use it to hash passwords for app storage, API secrets, or any system that expects bcrypt hashes. Verify with the bcrypt verifier tool.
Why is hashing slow?
Bcrypt is intentionally slow to resist brute force. Increase cost only if you accept longer login times; typical cost is 10–12.
Create Bcrypt Password gives you bcrypt hashes in one place: enter password, set cost, copy hash. No server, no account. For verification use Verify Bcrypt Password, for scrypt use Scrypt Generator, for random passwords use Password Generator, and for other hashes use Hash Generator.
Use the Create Bcrypt Password tool to generate bcrypt hashes.
