Can I download the NSRL hash set?
Each release of the NSRL hash set is made available for download free of charge one month after the subscriber CD release. The download comprises 4 ISO files which you can get from our downloads page. The ISO files can be downloaded and burned as a 4-CD set. You should verify the downloads are correct by comparing the value in the iso_hash.txt file to that published on the downloads page. You should also verify that the hash set is correct by using the hashes.txt and version.txt files you find on the CDs.
