The "deadly encryption" angle never made any sense in the movie. Spider was able to look at the data and even figure out what it was, but it didn't become lethal until it was actually transferred into another machine. I mean, duhhh, if you can look at the code, you can copy it at the same time.
In fact, looking at the code in any way is making a copy of it, from Max's head to Spider's screens (a copy is a copy is a copy!)
That was one of those conceits that nobody really thought through. Of course, Spider couldn't hatch his whole plan to legalize everybody without knowing what the code did in the first place.
