Hashing based idea
WebPBKDF2 requires that you select an internal hashing algorithm such as an HMAC or a variety of other hashing algorithms. HMAC-SHA-256 is widely supported and is recommended by NIST. The work factor for PBKDF2 is implemented through an iteration count, which should set differently based on the internal hashing algorithm used.
