Department of Homeland Security, federal, state, and local law enforcement, and the National Institute of Standards and Technology (NIST) to promote efficient and effective use of computer technology in the investigation of crimes involving computers. Numerous other sponsoring organizations from law enforcement, government, and industry are providing resources to accomplish these goals, in particular the FBI who provided the major impetus for creating the NSRL out of their ACES program.</p> <p>The National Software Reference Library (NSRL) is designed to collect software from various sources and incorporate file profiles computed from this software into a Reference Data Set (RDS) of information. The RDS can be used by law enforcement, government, and industry organizations to review files on a computer by matching file profiles in the RDS. This will help alleviate much of the effort involved in determining which files are important as evidence on computers or file systems that have been seized as part of criminal investigations.</p> <p>The RDS is a collection of digital signatures of known, traceable software applications. There are application hash values in the hash set which may be considered malicious, i.e. steganography tools and hacking scripts. There are no hash values of illicit data, i.e. child abuse images. The National Software Reference Library is a project in <a href="https://www.nist.gov/itl/ssd">Software and Systems Division</a> supported by <a href="https://www.nist.gov/forensic-science">NIST Special Programs Office</a>. </p> </div> </div> <div class="nist-block" >  <div data-elastic-exclude="" class="nist-tags"> <a href="/topic-terms/forensic-science" hreflang="en">Forensic Science</a>, <a href="/topic-terms/digital-evidence" hreflang="en">Digital evidence</a>, <a href="/topic-terms/information-technology" hreflang="en">Information technology</a> and <a href="/topic-terms/software-research" hreflang="en">Software research</a></div>  </div> </div> </div> </div> <div class="grid-container"> <div class="nist-page__region nist-page__region--content-bottom" > <div class="nist-block nist-block--contact" > <h2 class="nist-block__title" >Contacts</h2> <div class="nist-contact"> <ul class="nist-contact__items"> <li class="nist-contact__item"> <div class="nist-contact__name"> General Comments or Questions </div> <div> <a href="mailto:nsrl@nist.gov">nsrl@nist.gov</a> </div> <div> </div> </li> </ul> </div> </div> <div class="nist-block" > <div class="text-italic font-sans-2xs"> Created April 19, 2016, Updated January 27, 2022 </div> </div> </div> </div> </section> <nav role="navigation" aria-labelledby="book-label-793111" class="nist-booknav"> <ul> <li class="nist-booknav__item nist-booknav__item--next"> <a href="/itl/ssd/software-quality-group/national-software-reference-library-nsrl/curated-kaspersky-hash-set" rel="next" title="Go to next page" class="nist-booknav__link">Curated Kaspersky Hash Set - 2017 <b>›</b></a> </li> </ul> </nav> </div> <div data-elastic-exclude>  <footer class="nist-footer padding-bottom-4"> <div class="grid-container nist-footer__info"> <div class="grid-row"> <div class="tablet:grid-col-6"> <div class="nist-footer__logo"> <a href="/" title="National Institute of Standards and Technology" rel="home"> <img class="nist-footer__logo-img" src="/libraries/nist-component-library/dist/img/logo/NIST-Logo-Brand-White.svg" alt="National Institute of Standards and Technology logo" width="300px" height="42px" /> </a> </div> <div class="nist-footer__contact"> <h3 class="nist-footer__contact-heading">HEADQUARTERS</h3> <address> 100 Bureau Drive<br> Gaithersburg, MD 20899<br> <a href="tel:301-975-2000">301-975-2000</a> </address> <p> <a href="mailto:do-webmaster@nist.gov">Webmaster</a> | <a href="https://www.nist.gov/about-nist/contact-us">Contact Us</a> | <a href="https://www.nist.gov/visit">Our Other Offices</a> </p> </div> </div> <div class="tablet:grid-col-6"> <div class="nist-footer__social-links"> <a class="nist-social nist-social--x-white" href=" https://x.com/NIST"> <span>X.com</span> </a> <a class="nist-social nist-social--facebook-white" href=" https://www.facebook.com/NIST"> <span>Facebook</span> </a> <a class="nist-social nist-social--linkedin-white" href=" https://www.linkedin.com/company/nist"> <span>LinkedIn</span> </a> <a class="nist-social nist-social--instagram-white" href=" https://www.instagram.com/nist/"> <span>Instagram</span> </a> <a class="nist-social nist-social--youtube-white" href=" https://www.youtube.com/NIST"> <span>YouTube</span> </a> <a class="nist-social nist-social--giphy-white" href=" https://giphy.com/nist"> <span>Giphy</span> </a> <a class="nist-social nist-social--rss-white" href=" https://www.nist.gov/news-events/nist-rss-feeds"> <span>RSS Feed</span> </a> <a class="nist-social nist-social--envelope-white" href=" https://public.govdelivery.com/accounts/USNIST/subscriber/new"> <span>Mailing List</span> </a> </div> <div class="nist-footer__feedback"> How are we doing?
