Wow, I came up with an idea for a great site about a month ago, and have been doing some of the things I have read on here prior to finding this site at like 1:30 this morning. Great site, Wild Honey, it puts together a lot of the information I have been looking for to make my app even more secure prior to publishing to the web.
I have read a few books on the subject, though I am sure no where near enough, in trying to make everything as secure as possible. I love the idea of seasoning with salt. I have programmed in other languages VB, C#, JS, but not as much in PHP. Love the similarities, concerned about the security, just know how people are. You lock up something and somebody wants to break the lock, just to say they can if nothing else.
When I get everything set up I would love to have someone try to break it and let me know where I could improve. Heaven knows I am no expert on security. Hopefully though soon, I can at least claim to be in the ballpark.
