I should have started here: sub scrypt_hash { my ($key, $salt, $N, $r, $p) = _scrypt_extra(@_); return undef unless defined $key && defined $salt && defined $N && defined $r && defined $p; return "SCRYPT:$N:$r:$p:" . MIME::Base64::encode($salt, "") . ":" . MIME::Base64::encode($key, ""); } It explains that the last ...

r determines the sequential read size. This should only be changed if you have custom hardware that has a memory subsystem with different characteristics. It takes time to pull data from main memory, and the sequential read size allows the memory latency and CPU processing to be well-balanced on your system. Treat it like a constant unless you know what you'...
