Why would that be any better? If they get reverse engineered it would not be hard at all to get past that. Reason being that they both leave data in an easy to spot format. If you want to make it virtually impossible to reverse engineer (w/o seeing the script), combine the two strings and substring a few out. This will essentially take any possible footprint away and destroy the data. If they see your script, they would still have to cross-reference the two values that they see and try to triangulate the missing letters off of that.
