Bcrypt Generator
Generate bcrypt password hashes with adjustable cost.
Bcrypt is the industry-standard password hashing algorithm designed to be slow and resistant to brute-force attacks. Utilitoo's Bcrypt Generator creates bcrypt hashes from passwords or test strings with an adjustable cost factor - ideal for development, integration testing, and learning how bcrypt works without installing command-line tools.
Backend developers seeding test databases, security engineers verifying bcrypt integration, and students studying password storage all need a quick bcrypt hash generator. Adjust the cost factor from 4 to 15 to balance speed during development against production-strength hashing.
Enter text, set the cost factor, and click Generate bcrypt hash. Copy the full hash string including salt for use in test fixtures. Pair with Password Strength Checker for credential analysis, Password Generator for creating test passwords, or Hash Checker when verifying other hash types.
Hashing runs entirely in your browser on Utilitoo. Passwords are never uploaded or stored on any server. Free for development and testing - never use online tools with real production user passwords on shared machines.
Bcrypt Generator supports learning and development workflows where you need a quick cryptographic operation without opening a terminal. It is not a substitute for production key management, HSMs, or audited security infrastructure. Review Utilitoo's Privacy Policy if your organization restricts browser-based crypto tools.
Common use cases
- Generate bcrypt password hashes with adjustable cost - a common daily workflow on Utilitoo.
- Auditing secrets and credentials before committing code or sharing configs.
- Demonstrating bcrypt generator concepts in security training without exposing production keys.
- Quick checks on bcrypt generator output when you cannot use a local CLI tool.
- Cross-checking Bcrypt Generator output against a colleague's result during pair debugging or code review.
Tips & common mistakes
Bcrypt Generator is designed for development and education - never paste production secrets into any online tool unless you trust the privacy model. On Utilitoo, cryptographic operations run client-side, but you should still rotate credentials if they may have been exposed. Use generated passwords and tokens immediately and store them in a password manager rather than leaving them in browser history. Bcrypt Generator on Utilitoo runs client-side, so keys and plaintext you enter are not uploaded for processing. Still follow your organization's policy on secrets in browser tools, rotate any credential that may have been exposed, and prefer test keys when experimenting.
How to use
- Enter a password or test string.
- Choose a cost factor.
- Generate and copy the bcrypt hash.
Frequently Asked Questions
How do I generate a bcrypt hash online?▼
Enter your password or test string, choose a cost factor, and click Generate bcrypt hash in Utilitoo.
What cost factor should I use?▼
10 is a common default. Use lower values like 4 for fast tests and higher values like 12+ for production-style hashing.
Is bcrypt the same as SHA-256?▼
No. Bcrypt is designed for password storage with built-in salting and adjustable work factor. SHA-256 is a fast general-purpose hash.
Can I verify passwords with this tool?▼
This tool generates hashes only. Use your application's bcrypt verify function to check passwords against stored hashes.
Is my password uploaded during hashing?▼
No. Bcrypt hashing runs locally in your browser on Utilitoo.
