, Amazon EC2 is providing what they call “Cluster GPU Instances”: An instance in the Amazon cloud that provides you with the power of two NVIDIA Tesla “Fermi” M2050 GPUs. The exact specifications look like this:
22 GB of memory33.5 EC2 Compute Units (2 x Intel Xeon X5570, quad-core “Nehalem” architecture)2 x NVIDIA Tesla “Fermi” M2050 GPUs1690 GB of instance storage64-bit platformI/O Performance: Very High (10 Gigabit Ethernet)API name: cg1.4xlarge
GPUs are known to be the best hardware accelerator for cracking passwords, so I decided to give it a try: How fast can this instance type be used to crack SHA1 hashes?
Using the CUDA-Multiforce, I was able to crack all hashes from this file with a password length...
