Privacy With a 4096 Bit RSA Key — Offline, On Paper
HavanaF writes "Online backup is practical, but can it offer any privacy? The Dutch security company Safeberg developed an Offline Private Key Protocol, with an asymmetric key scheme. The protocol demands that the private (decryption) key be stored away from the 'source' computer, which presumably is 'too vulnerable.' The catch is that the private key needs to be fairly large to be secure: a 4,096-bit RSA key should suffice for some years. But how to store an 800-character key offline? Safeberg introduces a machine readable paper key, with the 4k-bit key crammed in a giant 2D Datamatrix barcode. This video on key strength tells the story."
... you fold the paper your 2D key is on? Tears, that's what. Tears.

Hang on! let me get my giant barcode out of my pocket!
I'll fax you a xerox of my public key. Is analog the new steam punk?
Nothing, but that poor guy will have to remember passwords for everyone!
How the fuck am I gonna back up to a remote server over the internet at 60 kbytes/sec?
you can get about 17 MBytes/Sec with a 1.5TB through USPS

They mean BESIDES the music, movies, and pr0n. You know, the [stuff] on your hard drive that's actually useful?
BLASPHEME!
Safeberg also announced that their official position is that "dog food tastes terrible".
Now that I think about it, I'm pretty sure everything I just said is completely wrong.
This makes absolutely no sense. Smart cards have been around for many years now. There, you NEVER give ANYONE or anything access to your private key. Challenge-response, one-time-passwords, tokens, etc, etc. Putting it on paper is LESS SECURE than sticking it on a thunb drive. Then at least it can't be stolen by taking a picture...

"Umm....let's see. Del Monte canned peaches in light syrup, kraft macaroni and cheese, hunts canned pizza sauce, campbels chicken and noodle soup"
"We need a Safeway, tape, scissors and a barcode reader!"
Online backup is practical
not for my 1.5 terabyte HDD which is about half full.
Right now backing up from hard drive to hard drive takes forever (hours). How the fuck am I gonna back up to a remote server over the internet at 60 kbytes/sec?
How much porn can one person watch, anyway? I mean, you have to leave time for Salshdot, too!

Liar! 17 Megabyte files always take 20 minutes to copy. Always.
... and then they built the supercollider.
when you put 4096 bit encryption into the hands of an average person, they really do type 12345 one hundred and sixty times.
I'm obviously above average then - i'd use cut & paste to do the job in seconds!
Does it come with a sticky backing so I can put it next to all the passwords I wrote down?
It takes a special kind of mind to do that.
And that said... I memorized a 48 character hexadecimal password, in case I ever need one. :P
I hope it wasn't F80FFA585E9867B804D998A2ED65E55BFC352C3C500684CC, cuz that's the one I'm using.

Damn thats the same combination I use on my luggage!
Watch me build my house
Those who would sacrifice latency for bandwidth deserve neither.
meh.
