A keygen for my Quay utility came out in January, too. Sales figures went to near-zero for over a month but have picked up slightly since then - however, it's a 7 Euro app and I haven't updated it for quite some time, so this may not apply to other cases. Also, nearly all of the referrals to my website now come from the torrent sites. I've been working with eSellerate support to find out how the keygen for Quay works. It's practically the same as the one for iCalViewer, except for the string(s) used by -[KGSerialNumberGenerator createSerial:]. Karl, maybe we should discuss this in detail? eSellerate serials use a public/private key scheme which works well in theory; in practice I think it's important to find out what happened here, since if there's some weakness in their scheme I won't reuse it for the upcoming 2.0 version. Of course, my idea of allowing existing users to simply re-use their old serials has now been torpedoed. -- Rainer Brockerhoff <[email protected]> Belo Horizonte, Brazil "In the affairs of others even fools are wise In their own business even sages err."
