          Current RDS Hash Sets

          RDS Version 2.67 - December 2019

          ISO 9660 images of RDS CDs

          If you have a fast Internet connection, you may download ISO 9660 image files and burn your own copy of the RDS CDs.

          Be aware that the ISO image files range between 500MB to nearly 4GB in size, and may take time to download.

          NOTE: This current distribution of the RDS is being served from the amazon cloud. You may receive a notice that you are leaving the NSRL website.

          The difference in the Modern sets are as follows:

          1. Modern RDS (microcomputer applications) - contains the comprehensive set of ALL appearances of files in? modern applications; many file entries are duplicated
          2. Modern RDS? (minimal) - contains the set of DISTINCT appearances of files in? modern applications; no file entries are duplicated
          3. Modern RDS? (unique) - contains the set of file entries that appear ONLY ONCE? in the entire NSRL collection; these are unique to each off the applications that are in the collection

          If a file exists with SHA1 value "024DD2A428CF0B450E461ED2A2EB6A1666CF392B" :

          • Set #1 can list ALL of the applications that contain the file.
          • Set #2 can list the fact that at least one application has that file.
          • Set #3 can list the single application that file with which that file must be associated (to the limit that NSRL has encountered it).

          The most common use is set #2.

          If you are interested in earlier releases of the RDS?contact us.?


          Hash Converter Windows GUI tool

          The MD5, SHA1 and SHA256 file signatures for these files are available here.

          There is a Windows GUI tool HashConverter.zip that the NSRL is allowed to redistribute.

          You can pick up the NSRL Perl conversion code at rds2hk.zip
          When you unpack the zip file, there is one file, "rds2hk.pl".

          enter: ?perl rds2hk.pl -h
          and you will get the help output: ?Usage : rds2hk.pl [-h] -f format [-d RDS_directory] [-l logfile] [-p product_id] [-u]
          -h : help with command line options
          -f format : one of hk , 1.5 , 2.0 (MANDATORY)
          -l logfile : print log info to a file
          -d dir : directory holding NSRLProd.txt, NSRLFile.txt NSRLOS.txt and NSRLMfg.txt
          -u : guarantee a unique product line in hk output

          Enter the command: ?perl rds2hk.pl -f hk -d SOME_DIR
          and you'll get two files, "outfile.hke" and "outfile.hsh" that you can rename and pull into Hashkeeper.
