Anyways: don't use 8192 bit keys. Whatever kills the 4096 bit keys is going to kill RSA along with them. Honestly, I think 4096 bits is also kind of a you're-kidding-yourself key length; if attacks on 2048 bit keys became tractable, RSA is probably in serious trouble.
I get truly excited when I see your replies, I'd love to banter in [inebriated] public! With that said, may I please make the humble request;
Yoou have contributed a shitload of awesome comments on the state f "who-the-fuck-are-we-kidding" with respect to encryption and privacy in light of what we actually know now related to the NSA....
Would you please create a post, in an Explain-Like-I-Am-Five-Years-Old manner on both the state of the capabilities of the NSA, the state of current encryption tech/methods we rely on, AND what the heck I, as and individual, could/can/should do about protecting myself.

I can speculate all day long about all sorts of things, but I am asking - given the NSA-Fatigue I suffer from - fr your help.
I WILL PAY YOU FOR THIS SERVICE; Set the price at $20 for the best recommendation. Crowd-source your network of people who have enough info to contribute to the recommendation...
Aside from smashing my machines and cancelling my power utility, I have no clue how to regain privacy at this point.
Then we will drink, and e Merry, Pippin and Sam!

Also, if you had a short string that could be expanded into the larger key, then what you really have is a short key to a slightly different crypto system, which is less secure than the original key in the original system.
Also, if you can significantly compress a string of truly random data, you can also probably compress digital video by a significant factor as well, and should therefore found a startup selling your groundbreaking compression technology.
