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
