Current RDS Hash Sets

RDS Version 2025.06.1 - June 1, 2025

Note: The NSRL has completed the transition away from the RDS 2.XX text file format, and will only be publishing the RDSv3 SQLite database format moving forward. If you still wish to use a text file format of the RDS, please reference the RDSv3_to_RDSv2_text_files.pdf document, which outlines the steps necessary in order to create RDS 2.XX like text files, from the minimal RDSv3 publications below.

RDSv3 Downloads

Please be aware that files of the RDSv3 format can be very large, and will take time to download. Please reference the RDSv3 README.txt files for exact download file sizes.

RDSv3 Publication History and Downloads

NOTE: As of the March 2025 RDS release, the split date between the Modern and Legacy hash sets has been updated on our standard five year cycle. Modern hash sets now contain data from software dating 2015 through the present, while Legacy hash sets now contain data from software dating 2014 and earlier. Be advised, his change has caused an overall decrease in the number of hashes published in the Modern set. 

RDSv3 Modern Minimal Database Demo Set

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. Please be aware that files of the RDSv3 format can be very large, and will take time to download. Please reference the README.txt file for exact file sizes.

There has been much interest by our users for including a minimal hash database version of the RDSv3 publication, which will reduce the size of the database and delta file downloads, by only including data that is equivalent to the old RDS 2.XX text files previously published by the NSRL. The minimal database publication mirrors the FILE, MFG, OS, and PKG views of the full publication database, but will only contain the set of FILE data that includes just distinct FILE rows (reference the minimal database schema included in the RDSv3.pdf).

Currently, the NSRL is only planning to publish the minimal database for the Modern hash set, officially starting with the December RDS publication, as this set has received the most interest for the inclusion of a minimal database. The NSRL may publish minimal databases for other hash sets, if there is sufficient demand.

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.
