About password_hash()
This tool runs actual PHP 8.2 code on our server using Docker containers. It executes real PHP's password_hash() function, ensuring 100% accurate results that match your production environment. The function creates a secure one-way hash of passwords using industry-standard algorithms.
- Creates secure password hashes
- Supports bcrypt and argon2 algorithms
- Includes random salt automatically
- One-way encryption (cannot be reversed)
- Use with password_verify() to check passwords
Algorithm Recommendations
PASSWORD_DEFAULT: Uses bcrypt currently. Recommended for most use cases as it automatically updates to stronger algorithms in future PHP versions.
PASSWORD_BCRYPT: Time-tested and widely used. Cost parameter (10-12 recommended) balances security and performance. Higher cost = exponentially slower.
PASSWORD_ARGON2ID: Most secure option, resistant to GPU and side-channel attacks. Recommended for high-security applications. Requires PHP 7.3+.
