It wont and is why I said in my previous post that the government is fighting a losing battle. We have already been down this road in the 90's with Phil Zimmerman. Zimmerman won because of something called the 1st amendment. Things get really dicey when the government wants to stop a person from publishing a book. They can't, and is again why they will lose. They might be able to make all American companies implement backdoors in their messaging protocols and smart phones, but they will have a VERY hard time convincing the courts that an individual cannot possess or write his own encryption software. Again, this is precisely what happened with Zimmerman in the 90's (inventor of PGP). Yes a backdoor would compromise it. However, one good thing about PGP is that they allow their source code to be reviewed by anyone. Even better, though, would be to use GnuPG which is a PGP clone that has zero commercial interests and is developed in open by a community of volunteers. You see, that's how the government (NSA) works -- they know they cannot overcome the first amendment, so they simply strong arm vendors and tell them they will go out of business if they don't implement backdoors. And the way they force them out of business is to deny them an export license (NSA has done this many times in the past). Yep and the terrorists are much more motivated to find a way than those of us who want to avoid casual snooping. This is a losing battle. Human intel is much more important today because of it.
