Further propelling the myth that encryption is worthless is that I often hear people saying that they heard that a 512 bit RSA key was broken. The truth of the matter is that 512 bit (and recently even 660 bit) RSA keys have been broken by the University of Bonn in Germany but that is has absolutely nothing to do with the type of encryption that’s used for ordinary bulk encryption. Furthermore, RSA’s inventors were well aware of the fact that it takes a much larger key to be secure which is why typical implementations are at a minimum 768 bits and can easily go up to 2048 bits and beyond. To give you an idea what it takes to break an RSA 1620 bit key, you would need a computer with 120 Terabytes of memory before you can even think about attempting it and the memory requirement virtually rules out massively distributed cracking methods. Some may ask why use RSA keys when it’s many orders of magnitude slower and requires so many more bits to be secure, the reason is that RSA encryption has the special property of being able to do secure key exchanges in plain sight of an adversary who is trying to break in but still remain safe. For this reason, RSA keys are strictly used for the initial phases of a secure communication session for the purpose of Authentication (where one entity proves who they are) and for secure key exchanges (used for bulk symmetric encryption). Once the initial transaction is complete, the key that was exchanged during the initial RSA phase can now be used for SSL or VPN bulk encryption with algorithms like RC5, 3DES, or AES.

POINT IN CASE. NOTHING IS UNHACKABLE, it just takes a matter of time.

Who are you to decide what we must read? Wouldn't it be nicer to use that space for a more informative description of your post?

yes a 'matter of time' is usually on the encrpytor's side however. Saying nothing is un-hackable is one thing, saying it will take an adversary several hundred years even with cluster computing is another. Encryption done properly is plenty secure and won’t be going away simply because lower bit ranges have been deemed crackable.
