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.
