On this page, we will make links available to data sets that use hashing or digest algorithms not contained in the RDS release. If there is an algorithm or process that you think would be interesting to run on the NSRL file corpus files found in the RDS (or on a subset of files), please contact nsrl [at] nist.gov (subject: , body: )  (nsrl[at]nist[dot]gov) .

**NOTE: These downloads are being served from the amazon cloud. You may receive a notice that you are leaving the NSRL website.**
                  - Data sets using the ssdeep algorithm (aka "fuzzy hashes") 
                  - Data sets using the sdhash algorithm (aka "similarity digest") 
                  - Data sets using the bulk_extractor tool

## Child Abuse Image Database (CAID) sets

The NSRL publishes JSON format sets of metadata about multimedia files which can be imported into CAID tools.

The current updates to the NIST NSRL CAID JSON are available for download with hash signatures at: RDS/CAID/current/NSRL-CAID-JSONs.zip.shaRDS/CAID/current/NSRL-CAID-JSONs.zip

The number of new files of each multimedia type in the current release are:

## SHA1 toSHA 256

A text file which relates SHA-1 to **SHA-256 hashes** is available.A 1.1 GB Zip file can be downloaded which contains a 1.9 GB text file with 16,801,737 rows.Each row has a SHA-1 hash, a tab character, a SHA-256 hash, a tab and a filename. An example of the data can be found here.

The SHA-1 values can be matched to SHA-1 values in RDS 2.41. Note: not all SHA-1 values in RDS 2.41 can be matched to SHA-256 values.

File signatures:SHA1(rds241-sha256.zip)= 3aa5dc0230444545a817cb9368bbfc28f4105822MD5(rds241-sha256.zip)= 87542ab5610dc673f4406d0f1c333c9eSHA1(rds241-sha256.txt)= 1580ecea496a34042f5b9db56e5f02307ffa68b9MD5(rds241-sha256.txt)= 83234d8f550dd32f8b3706e47d5dd3d9

Note: SHA-256 test data is available.

### **Hashes of Blocks of Files - MD5 of the first 4096 bytes.**

A text file is available which relates the MD5 of a complete file to the **MD5 of the first 4096 bytes** in the file (provided the file is that large).A 426 MB Zip file can be downloaded which contains a 823 MB text file with 13,112,687 rows.Each row has an MD5 hash, a tab character, and an MD5 hash.Example rows:
