With no mention of which specific card was used in the discovery, the card supposedly increased password recovery up to **10,000 percent faster**. Reports at this time are quite vague on the details, but if the claims hold any water at all, security experts could have a serious issue on their hands… > Brute force decryption of WPA and WPA2 systems using parallel processing has been on the theoretical possibilities horizon for quite some time now – and presumably employed by relevant government agencies in extreme situations. If tech savvy hackers at home get the chance to tap the power of GPUs for this purpose, a whole can of worms is about to open. ---

Ya this is gonna be a new wave of CPU intensive programming. Folding@home I think is already testing new software that used the idle GPU for folding too. ---

exactly… if a single GPU can process that much data, imagine what 15 or 20 (or more) can do in parallel. I wonder if this the end of traditional encryption as we know it ---

Just about anyone with enough know how and the $$$ to spend could create a farm dedicated to brute forcing encryption algorithms. the sky is the limit ---

You think the government doesn’t already have that? Regardless This isn’t breaking algorithms…this is brute forcing random password attempts agaisnt an encryption scheme… ---

The key words are “Brute force” it’s not actually re-calculating any algorithms. It’s just guessing really really fast… It’ll still take a million years for it to crack a 17 character code. ---
