Usage Guide

Password Hashing

Enter Password: Input the password you want to hash
Set Salt Rounds: Choose cost factor (10-12 recommended)
Generate Hash: Click generate or press Enter
Copy Result: Click the hash to copy automatically
Store Securely: Use the hash in your application

Password Verification

Enter Original Password: Input the plain text password
Enter Hash: Paste the bcrypt hash to verify against
Automatic Verification: Results display instantly
Check Result: Green indicates match, red indicates mismatch

Best Practices

Use cost factor 10-12 for most applications
Higher cost factors for high-security environments
Test performance impact in your specific environment
Store only the hash, never the plain password
Implement proper error handling for verification

Code Examples

JavaScript Integration

// Using bcryptjs library
const bcrypt = require('bcryptjs');

// Hash password
const saltRounds = 12;
const password = 'userPassword123';
const hash = await bcrypt.hash(password, saltRounds);

// Verify password
const isValid = await bcrypt.compare(password, hash);
console.log('Password valid:', isValid);

Python Integration

# Using bcrypt library
import bcrypt

# Hash password
password = b'userPassword123'
salt = bcrypt.gensalt(rounds=12)
hashed = bcrypt.hashpw(password, salt)

# Verify password
is_valid = bcrypt.checkpw(password, hashed)
print(f'Password valid: {is_valid}')

PHP Integration

// Using PHP's built-in functions
$password = 'userPassword123';

// Hash password
$hash = password_hash($password, PASSWORD_BCRYPT, ['cost' => 12]);

// Verify password
$is_valid = password_verify($password, $hash);
echo 'Password valid: ' . ($is_valid ? 'true' : 'false');

FAQ

What is bcrypt?

Bcrypt is a password hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher. It's specifically designed for password storage and includes built-in salt generation and configurable cost factors.

Why use bcrypt over other hash functions?

Bcrypt is adaptive - you can increase the cost factor as computers get faster. It's also specifically designed for password hashing, unlike general-purpose hash functions like SHA-256.

What cost factor should I use?

For most applications, use cost factor 10-12. Higher values provide more security but increase processing time. Test in your environment to find the right balance.

Is this tool secure?

Yes, all processing happens in your browser. Passwords are never sent to any server, ensuring complete privacy and security.

Can I use this for production applications?

This tool is perfect for testing and development. For production, implement bcrypt in your server-side code using the examples provided.

What's the difference between bcrypt variants?

$2a$: Original bcrypt
$2b$: Fixed version addressing a rare edge case
$2y$: PHP-specific variant

All variants are compatible for most use cases.
