🔐Bcrypt Hash Generator & Verifier Documentation & Guide
Security & Privacy
The Bcrypt Hash Generator & Verifier produces salted, slow-hash cryptographic password digests using the industry-standard Blowfish-based key derivation function and tests candidate passwords against existing hashes.
📋How to Use This Tool
- Select Operation: Choose Generate Bcrypt Hash to create a new hash or Verify Bcrypt Hash to test a password against an existing hash.
- Set Salt Rounds (Cost Factor): Select between 4 and 14 rounds (default 10 is standard for modern web applications).
- Execute: Click Generate Hash to compute the 60-character modular crypt format string.
- Verify Passwords: In verify mode, enter a candidate string and a hash to receive instant match confirmation.
⚙️Technical & Cryptographic Details
• Modular Crypt Format ($2b$): Hashes follow
$2b$[cost]$[22-char salt][31-char hash] containing the prefix, iteration power, and cryptographic salt.• Exponential Cost Scale: Each increment in rounds doubles the computational work (210 = 1,024 iterations vs 212 = 4,096 iterations), safeguarding against brute-force GPU attacks.
• Pure In-Browser Cryptography: Powered by client-side WebAssembly/JavaScript without sending cleartext passwords over the wire.
💡Practical Use Cases & Best Practices
- Generating test database seed passwords for authentication systems (Node.js, Laravel, Django, Spring Security).
- Testing and validating Bcrypt hash compatibility across programming languages and frameworks.
- Verifying whether a suspected plain-text password corresponds to an encrypted database hash during development audits.
100% Client-Side Privacy Guarantee:Passwords and salt rounds are calculated locally in your browser memory. No passwords or hashes are logged or shared.
