Bcrypt Hash Generator

What is Bcrypt Hashing?

Bcrypt is a password hashing function designed to be slow and computationally expensive, making it resistant to brute-force attacks. It's widely used for securely storing passwords and sensitive data.

Key Features:

• Salt: Bcrypt automatically generates and incorporates a salt, preventing rainbow table attacks.
• Adaptive: The cost factor (salt rounds) can be adjusted to make the hashing process slower as hardware improves.
• One-way: Bcrypt hashes cannot be reversed to obtain the original password.

How It Works:

1. A salt is generated (or provided).
2. The salt is combined with the password.
3. The result goes through multiple rounds of a key derivation function.
4. The final output is the Bcrypt hash, which includes the salt and cost factor.

Best Practices:

• Use a high enough cost factor (salt rounds) to make hashing take about 250ms on your server.
• Regularly update the cost factor as hardware improves.
• Never store plain-text passwords; always use hashing.
• Use a secure method to compare hashes when verifying passwords.

This generator helps you create Bcrypt hashes for passwords or sensitive data, enhancing the security of your applications by making stored credentials much harder to compromise.
