"... there will be no more public key algorithms."
Whoa! Calm down, calm down. It's not like this.
Together with quantum computers comes quantum criptography. Infact, the second one already exists in a very realibly form, although it is not commercially viable. It uses an initial data transfer to create a kind of public key. it is made on-the-fly and activelly by both sides, but it is still a kind public key.
But we don't need to go that far: nowadays there are non-quantum algorithms that are quantum computing resistant.
"God, PLEASE, if you exist, give Brazil the senses not to buy into this microsoft (...) addiction. (...)
Brazil, if you're listening, REGAIN your freedom and independence. (...)"
Sorry, God is unavaible at the moment. But his substitute has already dealt with this. You see, the Micromind proposal for shipping the "Connected PC" with its Windows X-tremelly Poor Sucker Edition was already rejected by the Brazillian government. I'm sorry I don't have an English link, but you can use the fish.
I can, however, translate the words of Sérgio Amadeu, director of the Federal Data Processing Service (SERPRO):
"We don't want to offer an inferior technology for those with lower income. This is discrimination."
"With Thunderbird, if you save a letter to send later, you have no way (that I can find) to send it, you have to restart the program for it to send it self, (in other words, there is no send button, just a recieve button)..."
Maybe I'm missing your point, but I believe there is a File -> Send messages in outbox menu option.
Yes, it is. Actually, there are two ways of achiving this:
One time pads. In order to this to work the key must be bigger than the message, and every new message must be encrypted with a new key (that's why it is called one time pads). So, every single character is encrypted with a new one. This limitation causes this method to be ununsable in a day-by-day basis. If the key is smaller or reused, the algorithm changes to a polyalphabetical one and the cyphered messages become vulnerable to frequency analysis.
Quantum cryptography. Using fotons with different alignments the two sides can combine a key for a one time pad, without the possibility of an eavesdropper knowing it by listening to their communication channel. If fact, in quantum physics, if you try to measure (or listen) to a particle, you change its behaviour, thus warning the party that there is someone tampering the channel. This method has not only been discovered, but already successfully implemented, even if for just a close range (and with limited funds). It is fearsible to believe that NSA and the WhiteHouse has such channel between then.
"Additionally, any kind of symmetric encryption must be considered weak; because if you can recover the encryption key somehow, you have the decryption key."
This is completelly off the point. You seem to be a crypto savvy, so probably you know this: "the secrecy must reside entirely in the key". When talking about cryptography, it is utterly important to "assume that the cryptanalyst has complete details of the cryptographic algorithm and implementation".
Knowing how the algoritm works is irrelevant, specially if you have an unlimited supply of encrypted messages, and, better yet, their equivalent clear-texts. Which, guess what, is this case.
If you have the key used for decryption, you have everything, no matter if it is a symmetric or asymmetric algorithm. So, for the sake of security, the key of a symmetric cypher must be as safe and the private key of an asymmetric one.
I agree with you when you say that "Any encryption algorithm is susceptible to brute force". Not talking about one time pads, which are mathematically unbreakable (if used correclty), time and computer power are still important to this. And we can't deny the possibility of great breakthroughs on prime numbers arithmetics and quantum computing.
And anyone, I repeat, ANYONE, who tries to predict the advances of 150 years in these areas is either a genius, or a complete idiot.
"

Well, you see, I agreed with you in the vast majority of you ideas. But "the average (...) slashdotter is a western (...) girl (...)" was really a huge escape from reality.
You're doing fine, you're smart. Maybe you should just go outside for a second and see what does a girl looks like... =)
"Microsoft can probably no longer buy their way into Government contracts with 'discounts' and whatever other tactics they might use."
Yes, they can. they can offer their software for free. Wait, they still had to open the source. I guess this is what they mean with "freedom is priceless".
The final number of deaths is 21. 16 bodies were already recovered. The Government is close to drop the hipotesis of human failure. Due to the violence of the explosion the bodies will be submited to DNA analysis for identification.

A great loss for my country, but we will not give up so easily to manage this technology (that is my point of view and our president's).
Agreed. It is a great service from an unknown person. However, it is not an ethical thing to to. Okay, Ethics vary from people to people, but this is very questionable.
The question is: "would fixing a computer without giving the user the option to accept it or not be a right thing?"
Starting from 16 of August machines infected with Lovsan will send massive amount of packets to windowsupdate.com. 40 byte packets are sent in 20 millisecond intervals to port 80. This might cause a Distributed Denial-of-Service attack on that website.
Let it spread freely! On August 16 I'll be trying to run it under Wine to see if I can be of some help.
Until now, I thought you were just another irritating poster. Now I realize that you're a dumb and irritating poster.
You have no clue what you are talking about, perhaps you'd do the world a favor if you'd just shut up.
What about know?
Whoa! Calm down, calm down. It's not like this.

I could put a link to my local copy of that chapter of the book, but I fear that my computer may get slashdotted.
Finished here too. Took 1h14m on my Duron 1GHz.
Don't forget that BZip2 has no "filesystem" capabilities, so you'll need to TAr ir first.

It worked beautifully on Hyrosima and Nagasaki, back in the 40's.

Wrong.
Quantum cryptography and one-time pads are truely, mathematically, Googlely unbreakable. See earlier posts.
Knowing how the algoritm works is irrelevant, specially if you have an unlimited supply of encrypted messages, and, better yet, their equivalent clear-texts. Which, guess what, is this case.
If you have the key used for decryption, you have everything, no matter if it is a symmetric or asymmetric algorithm. So, for the sake of security, the key of a symmetric cypher must be as safe and the private key of an asymmetric one.

"Heh, most of the NSA guys I've met (...)"
You don't exist. Go away!
Dude, I don't know what you have been smoking, but I want some of it!
If so, then let me see if I got it right:
- Mozilla does not sign Firefox.
- But Microsoft signs IE, and all the bugs that come along with it.
Well, this is a hard one.
Plain and simple.

Many may remember what happened when such things were tried to be implemented by a known Megacorp.
Me, I'd rather not be a luser and play by the book, updating my system frequently and using antiviruses on my Win machines.
