Bcrypt generator

5 of 1 ratings

Generate bcrypt hashes online for secure password storage and authentication. This bcrypt generator lets you create salted password hashes using the bcrypt algorithm, widely trusted in web development for its adaptive strength. Common long-tail needs include bcrypt hash generator online, create bcrypt password hash with salt, and bcrypt encryption for login systems.

What is Bcrypt?

Bcrypt is a password-hashing algorithm designed to be computationally expensive and resistant to brute-force attacks. Unlike simple hashing (MD5, SHA1), bcrypt automatically adds a unique salt and allows adjustable cost factors (work factors). This makes it a preferred choice for secure password hashing in applications, databases, and authentication APIs.

Why use a Bcrypt Generator?

Security by design: Each hash includes a salt, preventing rainbow table attacks.
Adjustable cost: Control the number of iterations (e.g., 10, 12, 14 rounds) to balance performance and protection.
Cross-platform: Bcrypt is supported in Node.js, PHP, Python, Java, C#, Go, and more.
Trusted standard: Recommended in OWASP guidelines and widely used in production systems.

How to use the Bcrypt Generator

Enter your password or string into the input field.
Select cost factor (commonly 10–12 for general use, higher for extra security).
Generate hash to receive a bcrypt string with salt included.
Copy and store the hash in your database for authentication systems.

Who should use it?

Web developers implementing secure login systems.
Database administrators ensuring stored credentials are properly hashed.
Security testers generating bcrypt values to validate authentication logic.
API developers protecting user accounts in modern applications.

Best practices

Never store plain-text passwords—always hash with bcrypt or similar secure algorithms.
Choose an appropriate cost factor: higher rounds = stronger, but slower (test server performance).
Verify with bcrypt libraries in your language of choice, don’t build custom crypto functions.
Upgrade gradually: increase cost factor over time as hardware becomes faster.

Code snippets

// Node.js
const bcrypt = require('bcrypt');
bcrypt.hash("myPassword", 10).then(hash => console.log(hash));

// Python
import bcrypt
print(bcrypt.hashpw(b"myPassword", bcrypt.gensalt(12)))

// PHP
echo password_hash("myPassword", PASSWORD_BCRYPT);

// Java
import org.mindrot.jbcrypt.BCrypt;
String hash = BCrypt.hashpw("myPassword", BCrypt.gensalt(12));
