PBKDF2 Hash Tool

PBKDF2 key derivation using Web Crypto API, supporting multiple hash algorithms

PBKDF2 Hash Usage Guide

About PBKDF2

  • PBKDF2 = Password-Based Key Derivation Function 2
  • RFC 2898 / PKCS#5 v2.0 standard algorithm
  • Uses Web Crypto API, secure and reliable
  • More iterations = more secure, but slower

Recommended Parameters

  • SHA-256 or SHA-512 as underlying hash
  • Iterations ≥ 100,000 (OWASP recommended)
  • Salt at least 16 bytes of random data
  • Output length 32 bytes (256 bits) is usually sufficient
