// Argon2 is a password-based key derivation algorithm
// defined in https://datatracker.ietf.org/doc/html/rfc9106
// It takes as input a password, a salt value, and a
// handful of additional parameters that control the
// cost of the operation. In this case, the higher
// the cost, the better the result. The length parameter
// defines the number of bytes that are generated.
// The salt must be as random as possible and should be
// at least 16 bytes in length.
