True, and 3DES provides an effective key length of about 108 bits. But
you still haven't cited your 128 bit DES example. It's not a jab; I
couldn't find it on googling, which is why I asked.
Not 108 bit but 112bit. I already cited
It has
been mathematically proved that by doubling the key length of the DES
algo, doesnt actually double the security it provides. Rather it
just simply remains the same.
It would certainly make a brute-force attack much harder. The
thinking machine does brute-force attacks remember :)

Just like encryption is breakable. Yes, RSA with 4096bit key is very
much breakable. Only problem is that we dont have enough computing
resources to break such keys.
How do you know that the NSA doesn't have the computing power already
and that they're not reading all GPG

Get your facts straight before you reply. a message encrypted with a 128
bit key DES is no more secure than a 64 bit key DES. Actually the length
of the key is only 56 bit in the latter case.
Please cite a source for this. I'd like to know how

@Dinesh: By definition, a brute-force attack is just cycling through
all the possible keys. Therefore, in general, greater the bits in the
key, the more combinations that require to be tested and hence harder
the brute-force attack. This

is very much breakable and that too in a practical amount of time.
Similarly, RSA will become breakable as the technology advances.
Not sure I agree with the flat analogy.

Good Article!
I especially like the analogy with the South Park Underpants Gnomes.
