"AES permits the use of 256-bit keys. Breaking a symmetric 256-bit key by brute force requires 2128 times more computational power than a 128-bit key. 50 supercomputers that could check a billion billion (1018) AES keys per second (if such a device could ever be made) would, in theory, require about 3×1051 years to exhaust the 256-bit key space."
And if you layer(SSL over AES VPN for example) your encryption, then completing that process just means that they get to start again with the next layer of encryption.
I'll chew up a lot of processing power making them decrypt the latest spam I have received or my online gaming session... lol.
