Bcrypt Hash Generator And Verifier

Generate secure password hashes and verify passwords using Bcrypt

Generate Hash

Higher cost means more secure but slower. Default: 10

Verify Hash


About Bcrypt Hash Generator

A secure online tool for generating and verifying Bcrypt password hashes. Bcrypt is a cryptographic hash function designed specifically for hashing passwords, incorporating a salt to protect against rainbow table attacks.

Key Features:

  • Generate secure Bcrypt password hashes
  • Verify existing Bcrypt hashes
  • Adjustable cost factor (4-31)
  • Client-side processing for security
  • No password storage or transmission

Important Security Notes:

  • This tool is for testing and educational purposes
  • For production use, implement password hashing on your server
  • Higher cost factors provide better security but slower processing
  • Default cost factor of 10 is suitable for most applications

Frequently Asked Questions

Bcrypt is a password hashing function designed to be slow and resistant to brute-force attacks. It incorporates a salt and cost factor to make the hashing process more secure. Unlike simple hash functions, Bcrypt is specifically designed for password storage.

The default cost factor of 10 is suitable for most applications. Higher values (up to 31) provide more security but take longer to process. Choose based on your security needs and performance requirements. For high-security applications, a cost factor of 12 or higher is recommended.

Yes, all processing is done in your browser. We never store or transmit your passwords or hashes. For production use, always implement password hashing on your server. This tool is intended for testing and educational purposes only.

Bcrypt offers several advantages:
  • Built-in salt generation
  • Adjustable work factor (cost)
  • Designed specifically for passwords
  • Resistant to rainbow table attacks
  • Industry-proven security

No, Bcrypt is a one-way hash function. You cannot recover the original password from a hash. This is a security feature. You can only verify if a given password matches the hash using the verify function.
