pub const RANDOM_SALT_LEN: usize = 16;Expand description
Salt length used by the *_with_random_salt entry points, in bytes.
16 is what RFC 9106 ยง4 recommends for password hashing, and is comfortably
above crate::params::MIN_SALT_LENGTH. It is a constant rather than an
argument because a caller who wants to choose the length also wants to
choose the bytes, and should call Argon2::hash_encoded with their own
salt instead.
