Easier to Crack Password

Cracking password nowadays is getting easier everyday. With the help of today's powerful computation and also newly developed resource-efficient algorithm, makes users's password seems less secure than before.

The latest version of John the Ripper (1.7.9-jumbo 6), well known password cracker is now able to crack password using GPUs via CUDA and OpenCL. This brings major improvements to it's performance.

Taken from H-Online:
In the case of sha512crypt, this means that the GPU on a GeForce GTX 570 graphics card can generate around 11,000 hashes per second – still more than five times faster than on a computer with eight CPU cores.
This means that we should pick our password more carefully. We can't just use the old method of selecting password, because it take less and less time to crack a password using today's tool and computing resources
