| Abstract | From the early days of computing, passwords have been considered as the essential authentication method to protect accesses to computer systems and users. Due to their importance, sensitiveness and confidentiality, many cryptography mechanisms have been utilized to secure password storage. Among them, cryptography hash methods are the most popular solutions. A cryptography hash function converts plaintext passwords to unreadable message digests which frustrates attackers from exploiting system failures and stealing stored passwords. On the other hand, it is possible to get the plaintext passwords from digests. We examined brute force attack to get the original passwords from the hashed ones and studied some existing GPU-based brute force cracking tools. These applications implement a hybrid algorithm that generates available passwords on CPU side and hashes them in parallel on GPU side. In this paper, we propose a new homogeneous parallel brute force cracking algorithm that performs all the works on GPU side. In our experiments, we successfully cracked many kinds of passwords. For example, with 6-digit passwords, it took about 0.23 ms for initialization, 1.97 ms for combination generation, and 52.81 ms for brute-force. So we need less than 1 second to crack passwords of this kind. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
