It's been awhile since I took basic algebra, but it would seem 76^12/25x=72000 seconds gives you the number of cards you need.  If I did the math correctly you only need around 200 Quadrillion gtx 1080 cards to brute force 12 character hashes in 2 hours. So with GTX 1080 cards being around \$700 today, you only need around 140 Quintillion dollars worth of GPUs.[/color] (07-10-2016, 04:51 AM)inprivate Wrote: (07-10-2016, 02:03 AM)kiara Wrote: (07-08-2016, 11:00 PM)Crackattack Wrote: How many titan x's would it take to crack any passwords up to 12-16 characters with capitals /characters / numbers etc with brute force type attack with the process only taking an hour or two lets start with, gtx 1080 cost less than titan x and perform better. so u should go with them. next thing, it depend on what alogirthim is being use.. a simple example, 8 gtx 1080 have the power to crack 200.3 GH/s  per sec lower case (26) + upper case (26) + num (10) + special char only !@#\$%^&*()_+-= (14) = 76 power 12 is  37133262473195501387776 possibility , now do the math how long that will take u  with 200Gh/s   (185666312365.977 second +-)about 5887 years « Next Oldest | Next Newest »
