Abstract
Though the History of using password in computing can be traced back to as far as mid of last century little focus has been implied on how to securely store and retrieve password to authenticate and authorize services to the end users. In this paper the current security of various password hashing schemes that are in use today will be investigated through practical proof of concept-GPU based, password hash dump cracking using the power of cloud computing. We will be providing comparison on different password hashing cracking time using the cloud GPU power in AWS. The focus of this paper is to show the possible use of cloud computing in cracking hash dumps and the way to countermeasures them by using secure hashing algorithm and using complex passwords.
Highlights
The most common means of authentication scheme are password-based authentication system [1]

Summary
The most common means of authentication scheme are password-based authentication system [1]. Businesses spend a tremendous amount of money for storing these passwords and for securing the storage of these passwords. When organization deals with a huge number of customers; it’s very hard for them to create, maintain and distribute these passwords across the network for authentication, authorization or accounting purposes. Passwords based authentication system possesses many security problems into rather relatively secured existing infrastructures [2].
