@Hyper_ you're an idiot.

Learn something about encryption, it's called research.

You're fucking stupid.

Your stupidity is amusing. Explain.
Do you know what one-time pad is?
I guess you are a member of the incoming skid invasion?

Show me a paper that says RSA 2048 has been factored, let alone 4096.
H Peter Anvin's key does not count, that was a special case.

"Security researchers have successfully broken one of the most secure encryption algorithms, 4096-bit RSA, by listening — yes, with a microphone"
I also said, it would be completely impossible with one-time pad, if you misunderstand the comment.

Side-channel attacks also don't count. You cannot do that to every implementation of RSA, or even a good implementation of RSA.
You also can't do that from more than a few meters away from someone actively decrypting or signing data with their RSA key.
Furthermore, an OTP is infeasible in most cases because of the sheer size of the key. It has to be as large as the plaintext to be entirely secure.
EDIT: He read this, then went to go Google something that makes me wrong. That's why he hasn't responded yet. Here, let me make it a little harder and quote something from your own link
Quote:Without going into too much detail, the researchers focused on a very specific encryption implementation: The GnuPG (an open/free version of PGP) 1.x implementation of the RSA cryptosystemGnuPG 1.* is basically dead. 2.0.27 is the current "stable" version, and this particular attack does not work on its implementation of RSA. Nor does it work on the "modern" GnuPG, or any smartcard implementation I'm aware of.
Even the "classic" version has been updated to defeat these side-channel attacks, as noted on gnupg.org
Quote:GnuPG 1.4.19 released (2015-02-27) important
GnuPG 1.4.19 is now available. This release mitigates two new of side channel attack methods as well as a couple of other bugs. {more}
If I am wrong, put your money where your mouth is. Factor my RSA public key and decrypt this.

Yes, now please tell me how to crack a remote box's 4096-bit encrypted SSH RSA key by listening to your computer. Oh wait, you fucking can't.
Like Reiko said, side channel attacks don't count because they're simply useless unless you have physical access to the computer. Kill yourself.
