It's inherently dangerous to assume that NSA doesn't pay much of attention to the breaking of fundamental crypto math based on these documents.
If they did find a practical weakness in RSA and such, I think it's safe to assume it would be assigned the highest level of secrecy and simply won't be in range of Snowden's document sweep.
If they do indeed - surely they would at least employ it in the backend to decrypt data? The documents we are seeing are geared towards analysts and provided from the groups implementing various attacks/capturing/decryption functionality. They wouldn't even have to reveal anything - just "give us data, we'll send you back decrypted results". Yet they frequently set rather low expectations for decryption. And then theres the organizational question. Why have groups targeting VPNs, IPSec, HTTPS etc. when breaking RSA gives you a golden key to any of these?
What I'm saying is these arguments routinely devolve into "it's so secret, they can't tell their own employees or analysts and they can't use it for the capability could be leaked". At that point the consequence is that the magic RSA breaking sauce becomes pointless as you can't use it, certainly not for the objective the NSA has spent the last decade on: capture everything.
I'm not saying they have it, but if they had it, they would be foolish to use it all over instead of only on key targets.
That's not what I said. Don't make shit up.
I said that one cannot rule out NSA sitting on an RSA weakness merely because it's not mentioned in the Snowden document dump.
The very fact that these low-level staffers were able to do as much damage as they're credited with should have been enough to force a house-cleaning of every affected agency, from the top down.
Additionally, one of the lessons learned from the 9/11 attacks was that keeping data too "Need to Know" might prevent people who actually need to know information from knowing about it.
When you have 10,000 documents labeled "top secret", instead of just 100, who really knows what's really important from that list, and doesn't need to be "as shared" anymore?
