About PBKDF2-SHA256
PBKDF2 (Password-Based Key Derivation Function 2) is a NIST-recommended password hashing algorithm. It applies HMAC-SHA256 iteratively to make brute-force attacks computationally expensive.
Higher cost factors increase the number of iterations exponentially (2^rounds), making each hash attempt slower for attackers.
