Google's Chrome OS revealed

Having the encryption key (which is FIXED for a majority of encryption algorithms) makes the decryption millions of times faster than if you didn't have it.

Customised key. As in, the end user gets to pick thier own key that they made.

Randomized key generation and assingment doesn't qualify as custom.

Ah, so now they are random :rolleyes:

I have a strange feeling that Android & Chrome OS will become one.

I think Google has admitted as much.

Well, it would've been stupid for them to keep them separate things, when Android is Linux and so's Chrome OS, so I don't think they'd really have a hard time of combining the two into one.

They have always been random?! What is wrong with you idiots?

"Fixed key" = You cannot change it. It is set by the administrator/software or other device and is out of your control.

Why are you people even bother to comment or argue the point if you don't even know the proper terminology or english required to understand?

Maybe i should start building a list of people to ignore, since you dont' even think for two seconds about what a person means when they write a post :p

PurePhoenix, I'd be careful who you insult, as it'll most likely get you a warning, most of the users on here have been here far longer than you.

so what your saying is .... fixed key = not random , all they need to do is get that key and they'll get through?

PurePhoenix's original claims:

Uhh he's actually right. Having the encryption key (which is FIXED for a majority of encryption algorithms) makes the decryption millions of times faster than if you didn't have it.

Read, only one of the top six allows you to use a customised key.

The algorithm never changes. Values != algorithm.

Learn to read & comprehend a post.

In the first one, you claim that the key is fixed for a majority of algorithms. The implication being that secret algorithms and implementations are more secure than those that are publicly disclosed. You were then asked to provide evidence for this, which lead to the second post I quote. Here you say that only "one of the top six" algorithms allow you to use a "customized key" (presumably the other five use fixed keys then.) Nothing in the link you provide says that, so again, what are you basing this on?

The reality is that you are simply wrong. All the major algorithms certainly do not have fixed keys. It's also widely accepted that exposing the algorithm to public scrutiny and review actually leads to safer solutions, as potential weaknesses are more likely to be found. The end result is a more secure product.

Are you ready to recognize that you were mistaken? I see that you have in your last few posts changed your position to complain about keys being "random." I still expect you to respond to the above that disputes your original claim. Are we to understand that you are retracting your earlier claims?

Your new claim doesn't really make any sense either, though. How the key is created is separate from the algorithm. An implementation that protected the key with a random three-letter password would obviously not be very secure, even though the algorithm is solid. This defect would not be in the algorithm. I think you'll also have to explain to us why you believe a (pseudo-)randomly generated 256-bit key makes the system less secure than if you could "make it yourself" (whatever that means in this context.) How does that follow? How does this make the key easier to guess?

What's the problem with pseudo-random generation? It's probably a hell of a lot more secure than any passphrase you can come up with.

If your concept of proper terminology is that "random = fixed" then I'm done arguing with your :p

Gotta appreciate the subtle backpedaling though.
