Overview
Our Bcrypt Hash Generator is a free, secure tool for developers and system administrators to instantly generate cryptographically strong bcrypt hashes. Bcrypt is the industry standard for password hashing because it incorporates a salt to protect against rainbow table attacks and uses an adaptive cost factor (rounds) to resist brute-force hardware attacks. This tool runs 100% locally in your browser, meaning your plain-text passwords never leave your device.
Key Features
Generate secure bcrypt hashes instantly
Adjustable cost factor (Salt Rounds from 4 to 15)
Automatically generates cryptographically secure salts
100% client-side processing — absolute privacy
One-click copy to clipboard functionality
How to Use Bcrypt Generator
1Enter the plain-text string (usually a password) you want to hash.
2Select the number of 'Salt Rounds' (Cost Factor). Higher rounds are more secure but take longer to calculate.
3Click the 'Generate Hash' button.
4Your secure bcrypt hash will appear in the output panel.
5Use the 'Copy' button to copy the hash to your clipboard.
Benefits
- Test database seed passwords without writing temporary scripts.
- Verify the output format of bcrypt implementations in your own code.
- Complete security and privacy since no data is ever transmitted to a server.
- Instantly generate admin credentials for local development environments.
Common Use Cases
Database Seeding
When creating initial database seed scripts for a new web application, you need pre-hashed passwords for default admin accounts. This tool generates them instantly.
Security Auditing
Understand how changing the cost factor (rounds) drastically increases the computational time required to generate a hash.
Local Development
Quickly generate a hash to manually insert into your local database to bypass forgotten passwords during development.
Tips & Best Practices
- A salt round of 10 or 12 is currently considered the industry standard balance between security and performance.
- Each increase in the salt round doubles the amount of time it takes to calculate the hash.
- Because the salt is randomly generated each time, hashing the exact same password twice will produce two entirely different hashes (which is exactly what makes bcrypt secure!).
