PBKDF2 (Password-Based Key Derivation Function 2) derives a cryptographic key from a password using repeated hashing. It's designed to slow brute-force attacks through high iteration counts.
10,000 iterations provides a balance between security and performance. Modern standards recommend higher counts (100,000+), but 10,000 is suitable for password storage simulation.
The default is 10,000 iterations for password storage simulation. Higher iteration counts increase security but slow down generation. The tool uses fixed 10,000 for simulation.
The hash is displayed as a hex-encoded string. The tool shows the derived key along with the salt used (randomly generated if not provided).
No. All hashing happens locally in your browser using the Web Crypto API. No password or hash data is transmitted.
