128-bit encryption means 128 bits.

The number of permutations is 2^128, or 340282366920938000000000000000000000000 possible permutations.

Even with really fast processors, it would take months to brute force that. Assuming you don't really have access to some kind of supercomputer or massive distributed computing network.

Although a few recent papers have called into question the security. AES-128 encryption. If you like technical stuff, here:

Although they conclude the encryption is fairly secure at this time, some flaws have started to appear.
