Remember about NSA? they can crack about anything,can enter/hack into almost anything
No they can't. If you look at all the Snowden releases, the NSA has tremendous reach and intercepted things that is shocking and disturbing. However, none of what they did was technically complex. It just requires a lot of money, power, and boots on the ground.
Virtually none of what they discovered was done by physically breaking encryption - it was open phonelines, emails, unprotected servers, snitches, co-operation from telecom companies, co-operation from companies that release encryption software to introduce backdoors for the NSA etc.
