About PBKDF2
PBKDF2 (Password-Based Key Derivation Function 2) is a key derivation function that 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.
- Recommended by NIST for password storage and key derivation
- Salt prevents rainbow table attacks - always use unique salts
- Higher iteration counts slow down brute-force attacks
- Minimum 100,000 iterations recommended for password hashing (2024)
- Output key length should match your encryption algorithm requirements
