PBKDF2 (Password-Based Key Derivation Function 2) is a key derivation function defined in PKCS#5. It applies a pseudorandom function (like HMAC-SHA256) to the input password along with a salt value and repeats the process many times to produce a derived key. PBKDF2 is widely used for password storage (Linux /etc/shadow), WiFi WPA2 encryption, and disk encryption (FileVault, BitLocker).
A salt is random data mixed with the password before hashing, preventing rainbow table attacks — identical passwords produce different hashes with different salts. Iterations increase computational cost for attackers: 100,000 iterations means each password guess requires 100,000 hash computations. OWASP recommends at least 600,000 iterations for critical systems.
PBKDF2 (2000) is the earliest KDF, widely supported (native in browser Web Crypto API), but weaker against GPU/ASIC attacks. bcrypt (1999) has stronger GPU resistance. scrypt (2009) adds memory hardness. Argon2 (2015) is the PHC winner with best GPU/ASIC resistance and memory hardness. This tool uses Web Crypto API's native PBKDF2 — no external library needed.

No. All computation uses the browser's built-in Web Crypto API (SubtleCrypto) for PBKDF2 key derivation. Your password, salt, and derived key never leave your device. This ensures complete privacy for sensitive cryptographic operations.
