Unfragile

The request is for scrypt, a password-based key derivation function. None of the candidate sources documents scrypt directly; the closest relevant candidate is the Cryptography library, whose page describes key derivation functions and high-level recipes 4. Its page does not name scrypt explicitly, so the fit is inferred rather than confirmed.
