Bcrypt Password Tool

Encrypt and verify passwords securely with bcrypt

Type a password
Custom salt is rarely needed — bcrypt embeds it automatically.

Encrypted Hash

📌 Store this hash — it includes the salt and algorithm parameters. Use the Verify tab to check a password against this hash later.

🔍 How verification works:
• Enter the plain-text password you want to check
• Paste the bcrypt hash stored in your database
• The salt and rounds are automatically extracted from the hash

🔒 Security Best Practices:
• Always use bcrypt or similar for password storage — never store plain text.
• Use at least 12 rounds in production.
• Implement rate limiting on login attempts.
• Always use HTTPS for password transmission.

🔐 Online Bcrypt Password Generator & Verifier Tool

Securely hash, encrypt, and verify passwords instantly with our Free Online Bcrypt Password Tool. Designed for developers, cybersecurity professionals, and database administrators, this browser-based utility allows you to generate salted bcrypt hashes and test password matches in real time without sending sensitive data over the network.

🌟 Key Features of Bcrypt Password Tool

  • 🛡️ Production-Ready Bcrypt Hashing: Generate industry-standard $2a$, $2b$, or $2y$ bcrypt hashes protected by adaptive key derivation functions.
  • ⚙️ Adjustable Work Factor (Salt Rounds): Easily customize cost factor rounds (from 4 to 14) to balance computational security and execution performance.
  • ✅ Instant Match Verification: Compare plain-text strings against existing bcrypt hash strings to verify authentication logic without backend deployments.
  • 🔒 100% Client-Side Processing: All cryptographic hashing and salt operations run directly inside your browser’s JavaScript engine—your plain-text passwords never touch external servers.
  • 📋 One-Click Copy: Seamlessly copy generated hash strings directly to your clipboard for database seeding or testing.

💡 How to Use the Bcrypt Password Tool ?

1. Hash a Password

  1. Enter your plain-text string into the Input Password field.
  2. Select your desired Salt Rounds (Default: 10 for optimal balance of speed and security).
  3. Click Generate Hash to receive a secure 60-character bcrypt output string.

2. Verify a Hash

  1. Paste the existing hash string into the Bcrypt Hash box.
  2. Enter the candidate plain-text password into the Verify Password input.
  3. Click Check Match for an immediate boolean validation (Match / No Match).

❓ Frequently Asked Questions (FAQ)

Is bcrypt reversible?

No, bcrypt is a one-way password hashing algorithm (based on the Blowfish cipher), not a symmetric encryption method. It cannot be decrypted back into plain text.

Why is bcrypt better than MD5 or SHA-256 for passwords?

MD5 and SHA-256 are fast cryptographic hashes prone to brute-force and rainbow table attacks. Bcrypt incorporates a unique random salt and an adjustable cost factor, making brute-force attempts computationally expensive for attackers.

Are my passwords stored on your server?

No. Hashing and verification run locally in your web browser. No plain-text passwords or hash strings are transmitted or stored anywhere.
