PBKDF2 Key Derivation - Free Online Tool | PivaBox

Derive cryptographic keys from passwords using PBKDF2 — configurable iterations, salt, and hash algorithm

How to Use PBKDF2 Key Derivation

1. Enter your password and provide a salt value — click the dice button to auto-generate a random 16-byte salt
2. Configure the iterations (higher is more secure but slower), key length in bits, and hash algorithm (SHA-256, SHA-384, or SHA-512)
3. Click Derive Key to compute the PBKDF2-derived key — copy the result or use the verify section to confirm against a known value

Frequently Asked Questions

Is PBKDF2 Key Derivation free?

Yes, PivaBox PBKDF2 Key Derivation is completely free to use. All computation runs locally in your browser using the Web Crypto API.

Is my password uploaded to a server?

No. All key derivation happens entirely in your browser using <code>crypto.subtle.deriveBits()</code>. Your password and derived keys never leave your device.

How many iterations should I use?

For production use, at least <strong>100,000 iterations</strong> with SHA-256 is recommended by OWASP. Higher values (300,000+) provide better protection against brute-force attacks but increase computation time. The default of 100,000 balances security and usability.
