Just out of curiosity - assume you took a key of 8096 bits - and it is super long - could you then make a hash of the key which were shorter, and provide the hash, with instructions on how to reverse it, and then use the hash to produce the 8096 keylength with less digits between you and the recipient?
Are you asking whether you can compress an RSA key?
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.
Dude, Get your ass to SF so I can buy you the many beers I owe you!
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!

No - one of the main points of a hash is that it is non-reversible.
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.
