Calibrate returns the hardest parameters (not weaker than the given params), allowed by the given limits.

CompareHashAndPassword compares a derived key with the possible cleartext equivalent.

Cost returns the scrypt parameters used to generate the derived key.

Key derived key for e.g.

DefaultParams provides sensible default inputs into the scrypt function for interactive use (i.e.

ErrInvalidHash is returned when failing to parse a provided scrypt hash and/or parameters.

ErrInvalidParams is returned when the cost parameters (N, r, p), salt length or derived key length are invalid.

ErrMismatchedHashAndPassword is returned when a password (hashed) and given hash do not match.

Params store values for scrypt encryption.
