How to calculate the checksum of a Qlik patch or installer

[JCLamoure]

After downloading a Qlik product installer or patch, you may want to verify the checksum of the file. This article explains how to compute the checksum with the MD5 hash.

This applies to products such as Qlik Talend Studio, Qlik Sense Enterprise on Windows, and similar. 

On Windows

With PowerShell, using get-Filehash

Command: get-Filehash -algorithm

Example:

get-Filehash .\Patch_20201218_R2020-12_v1-7.3.1.zip -algorithm md5

Output:

Algorithm       Hash                                                                   Path
---------       ----                                                                   ----
MD5             A18D537FE8F466643FF2B36DC0713D9F                                       C:\tmp\Patch_20201218_R2020-12_v1-7.3.1.zip

From the command prompt, using certutil

Command: CertUtil

Example:

CertUtil -hashfile Patch_20201218_R2020-12_v1-7.3.1.zip MD5

Output:

MD5 hash of Patch_20201218_R2020-12_v1-7.3.1.zip:
a18d537fe8f466643ff2b36dc0713d9f
CertUtil: -hashfile command completed successfully.

On Linux systems

Use either cksum or md5sum.

Command: cksum
Command: md5sum

Example:

# cksum Patch_20201218_R2020-12_v1-7.3.1.zip

Output:

2689783428 702238968 Patch_20201218_R2020-12_v1-7.3.1.zip

Example:

# md5sum Patch_20201218_R2020-12_v1-7.3.1.zip

Output:

a18d537fe8f466643ff2b36dc0713d9f  Patch_20201218_R2020-12_v1-7.3.1.zip
