I need to hide a string in the source code of my program. Searching I found a programmer who hid the phrase "Hello World!" through a string of if and loop repetition attaching everything to a numeric array.
The work can be viewed here .
I ask, does either work have practical results or is it easily undone?
It depends. Want to hide from a curious any and if it is discovered no problem? Then it does.
Do you want security? Can information not be discovered? So do not even tickle. This is extraordinarily easy to obtain if the person knows how to do it. You do not even have to understand math or take the time to find a logic in it. It takes more work to "protect" than unprotect.
Security is something difficult and usually only done right by experts, which is rare to find and even these make mistakes. Of course there are some rules that can be followed for the basics and this means delegating almost everything to something proven and giving little or no physical access to the information you want to protect.
