By definition, if you create a security system with a "back door" that security system is not secure. If the NSA can open the back door, so can other hackers. RSA has created a Potemkin Village security system.
And keep in mind; where you have an omni-potent, omni-funded, omni-secret government operation you have wormholes in systems that probably shouldn't have holes. Al-la Doctor Strangelove. How do you recall a B-52, a nuke sub, a commando unit? This thinking is you build in code that can be hacked and you pay for it.
Let's hope we have the resources when it's time to pay the piper.
It is simply wrong to trust these people. Government on steroids is going to be the death of us.
