Which Crypto Hashing Method is a Gas … And is as Slow as You Want and breaks GPUs?

The Hashing Method Designed To Defeat GPUs

Introduction

Did you know that every eight character password (in lowercase) is cracked by brute force within less than 10 seconds on a GPU device? And if you use a nine character password it takes less than 10 minutes to crack them (using lowercase letters)? Adding a number to the end, or making the first letter uppercase makes very little difference in the cracking challenge [here]:

Here is me using an eight GPU instance in the Amazon Cloud (cost of $7/hr):

Thus we need to give up on our traditional ways of generating encryption keys or in creating hashed versions of passwords, as our passwords are often guessable. For MD5 we can now get billions or even trillions or hashes per second, where even 9 or 10 character…
