Abstract: Though the History of using password in computing can be traced back to asfar as mid of last century little focus has been implied on how to securelystore and retrieve password to authenticate and authorize services to the endusers. In this paper the current security of various password hashing schemesthat are in use today will be investigated through practical proof of concept-GPU based, password hash dump cracking using the power of cloudcomputing. We will be providing comparison on different password hashingcracking time using the cloud GPU power in AWS. The focus of this paper isto show the possible use of cloud computing in cracking hash dumps and theway to countermeasures them by using secure hashing algorithm and usingcomplex passwords.
