Bcrypt Hash Generator

Generate secure bcrypt password hashes with configurable cost factors and salt generation for secure password storage.

Password to Hash

The password you want to hash securely

Cost Factor (Rounds)

2^10 = 1,024 iterations (~<100ms)

Cost Factor Recommendations

Development

4-6 rounds: Fast for testing
8 rounds: Good for development
Trade-off: Speed over security

Production

10 rounds: Minimum recommended
12 rounds: Good balance
14-15 rounds: High security

Bcrypt security benefits

Adaptive cost: Can increase difficulty over time as hardware improves
Built-in salt: Each hash includes a unique salt to prevent rainbow table attacks
Time-tested: Industry standard for password hashing since 1999
Slow by design: Computationally expensive to discourage brute force attacks

Usage in Applications

Node.js (bcrypt library)

const bcrypt = require('bcrypt');
const saltRounds = 10;

// Hash password
const hash = await bcrypt.hash('mypassword123', saltRounds);

// Verify password
const match = await bcrypt.compare('mypassword123', hash);

Python (bcrypt library)

import bcrypt

# Hash password
password = b'mypassword123'
hash = bcrypt.hashpw(password, bcrypt.gensalt(rounds=10))

# Verify password
match = bcrypt.checkpw(password, hash)

Generate Bcrypt in Terminal

Apache htpasswd utility

$htpasswd -bnBC 10 "" "mypassword123" | tr -d ':\n'

Python bcrypt

$python3 -c "import bcrypt; print(bcrypt.hashpw(b'mypassword123', bcrypt.gensalt(rounds=10)).decode())"

Node.js bcrypt

$node -e "console.log(require('bcrypt').hashSync('mypassword123', 10))"
