could add rounds when hash ？

[wuxiao-ling197]

hello , to enforce the hashed password security level in prod environment , i`d think whether golang can add its rounds like passlib usage in python:

pwd_context = CryptContext(
    schemes=["pbkdf2_sha256"],
    default="pbkdf2_sha256",
    pbkdf2_sha256__default_rounds=30000
 )
