NSRL Downloads

signatures of the four ISO images
disc 1 (non-English software)
disc 2 (operating systems)
disc 3 (application software)
NOTE: the NSRLFile.txt file on disc 3 is over 2GB in size. Ensure your OS can handle this correctly.
disc 4 (images & graphics)
description of the RDS contents

It is your responsibility to verify the ISO image files with the signatures and file sizes once they are downloaded. After you have used the image to create a CD, it is your responsibility to verify the data files on that CD with the signatures provided on that CD.

Converting RDS format to other formats

There is a Windows GUI tool HashConverter.zip that the NSRL is allowed 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
      -p integer : use one ProductCode from NSRLProd.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.

Mappings of File SHA-1s to Path/File names

The project was not initially collecting the full path information for all of the files on all of the media in the NSRL collection, but we have some of that data, and it is available here.

You can download a zipped text file, NSRLLocn.txt, which contains the SHA-1, AppID, MediaID, and full path string for 28,569,382 files as of Jan. 7, 2004.

The SHA-1 of the zip file is 7E0B63CDFDBAC7D4664057F15FC7AC66ABE0E2EB and the MD5 is 59C2AB12EBB966C7F984B63D4C057B20 . The size is 460 MB.
