About

PBKDF2 (Password-Based Key Derivation Function 2) is a key derivation function specified in PKCS #5 and updated by RFC 8018, using HMAC with configurable iterations to slow down brute-force attacks and derive secure keys from passwords.

Use Cases

  • — Password hashing for user authentication
  • — Deriving encryption keys from passwords
  • — WiFi WPA/WPA2 key derivation
  • — Apple iOS keychain encryption
  • — Legacy password storage systems

Security Notice

PBKDF2 requires high iteration counts (100,000+) for security. For new systems, consider Argon2id as a more modern alternative.
