RDS Version 2.77 - June 2022

RDSv3 Version 2022.06.1 Delta - June 2022

Version 2022.06.1 is the second production release of the RDSv3 format. This publication contains SQLite files, which are intended to update the SQLite database files published in first RDSv3 publication, RDS 2022.03.1. This publication is the next step in the transition away from the flat text file format of RDS 2.XX, to the SQLite database format, which includes SHA-256 hashes, while removing the CRC-32 hash, among other publication changes. The new RDSv3 format will be the only publication format released by the NSRL beginning March 2023. All production publications of the RDSv3 format may be downloaded below.

For a more detailed description of the RDSv3 publication format, please download the demonstration set below, and the information documents associated with the set.

UDF images of RDS 2.77 CDs

If you have a fast Internet connection, you may download UDF image files and burn your own copy of the RDS CDs. Be aware that the UDF 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.

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.
