Bcrypt Password Hash Generator & Verifier

Generate and verify bcrypt password hashes with adjustable cost factors for secure password storage.

⚠️ Demo Mode

This tool simulates bcrypt hashing for demonstration purposes. For production use, implement proper bcrypt using bcryptjs or similar libraries server-side.

Generate Hash

Higher values = more secure but slower (recommended: 10-12)

Verify Hash

About Bcrypt:

  • Designed specifically for password hashing
  • Automatically includes salt in the hash
  • Cost factor makes brute-force attacks expensive
  • Each hash is unique even for the same password

How to Use Bcrypt Generator

  1. 1

    Enter your password to hash.

  2. 2

    Adjust the cost factor (4-20, recommended 10-12).

  3. 3

    Click "Generate Bcrypt Hash" to create the hash.

  4. 4

    Use the verifier to check if a password matches a hash.

Frequently Asked Questions

What is bcrypt?

Bcrypt is a password hashing function designed specifically for secure password storage, with built-in salting and adjustable computational cost.

What is the cost factor?

The cost factor determines how many times the hashing algorithm runs. Higher values (12+) are more secure but slower, making brute-force attacks more expensive.

Why is each hash different?

Bcrypt automatically generates a unique random salt for each password, so the same password creates different hashes, preventing rainbow table attacks.
