PBKDF2 Key Derivation

Derive fixed-length key material from a passphrase, salt, iteration count, and hash using the browser Web Crypto API. Inputs are not uploaded.

Security Notes

  • The salt and parameters are required to reproduce a key
  • Use a unique random salt; it is not a password
  • For new password-storage systems, evaluate Argon2id; this output is raw derived key material, not a complete password record
