Its a fairly safe bet they could if they wanted to.
No. They couldn't.
They have broken Tor, SSL, 128 bit and 256 bit encryption. I know of only one encryption system that I doubt the government has broken and that is 4096 bit. used by a site in Europe. The encryption key is held by the user and NOT recorded by the site.
This is literally nothing but jibberish. Tor is just a proxy service that is still up and running so please explain what they "broke". How exactly did they break SSL, 128 and 256 bit encryption when they are all end to end schemes? That makes no sense. It sounds like you read some alarmist blog post filled with misinformation and now you're spreading that around. I work in IT security for a living and your claims make no sense.
"Tor is software that you can install on your PC to hide your identity as you browse the web, send emails, and share files. It encrypts anything sent from your PC, so that no one can see who or where you are, even when you are logged into a website using your real name." So, if someone can hack in, identify you, read your emails, find what files you have shared and where you have been browsing, DESPITE your use of Tor, then obviously that person has BROKEN the encryption and purpose and objective of the TOR program.
WHAT PART OF THAT SIMPLE CONCEPT IS JIBBERISH?
You also should not be working in IT if you don't know how encryption is broken.
