MD5 hash values for datapacks and data files are available when using Install Manager at release 2020Q1.0 or later. The values are written to text files at the end of download and installation processes. The new files containing MD5 hash values are located in both the download and data installation folders, and will only be included for data and certification products that have been selected for download (not for all products listed in the license key).

Sample File Names

From the Download folder (datapack download):
  • datapacks_server_md5_2020-01-28_15-08-11.txt
  • datapacks_local_md5_2020-01-28_15-59-27.txt
From the Data folder (dataset install):
  • data_server_md5_2020-01-28_16-45-02.txt

Certified Product Data

MD5 hash values for certification products (CASS, AMAS, and SERP) are available when using Install Manager version 12.0.0 or later (first released in 2020Q2.0). These are written to txt files following the download and installation. Certification datapacks (*.lfz) will be written to datapacks_* file under the download folder. Starting with the 2020Q2.0 release, the data folder will include two new files for the md5sum hash values for certifications:
  • certification_server_md5_<timestamp>.txt
  • certification_local_md5_<timestamp>.txt

​
MD5 Hashes Footnotes

  • MD5 hash values are not available for offline installations. This is because the hashes are generated from information provided by the licensing web service when a license key is queried.
  • The hash files in the data folder (data_local_md5_<timestamp>.txt and data_server_md5_<timestamp>.txt) will have the same timestamp. This is because the server generated hash was retrieved by the install manager but not written until the local hashes have been computed.
