Using CheckSum to verify CloudExtend downloads

Learn how to confirm the authenticity and integrity of CloudExtend-provided files

Updated this week

Sometimes the CloudExtend support team may provide a direct download link for a configuration file, script, diagnostic tool, or registry file.
​

To ensure the file downloaded correctly and has not been altered or corrupted, the download link may also include a checksum value, such as:

0ad3e986030a505ce8f0e000c2785e2c

This checksum lets you verify that the file you downloaded exactly matches the original file CloudExtend published.

What Is a Checksum?

A checksum is a unique string of letters and numbers generated from a file using a mathematical algorithm (CloudExtend uses MD5).
​
If even a single byte changes during download or storage, the checksum will not match.

Checksums help confirm:

  • File authenticity

  • File integrity

  • That no corruption occurred during download or transfer

When Should You Verify a Checksum?

Checksum verification is helpful when:

  • A download fails or seems incomplete

  • Network issues may have interrupted file transfer

  • Security policies require integrity validation

  • You want to confirm the file is unaltered before applying system changes (e.g., registry edits)

If the checksum does not match, the file may be corrupted or modified.

How to Verify a Checksum Value

CloudExtend provides MD5 checksum values for verification.

  1. Locate the checksum CloudExtend provided (usually next to the download link).

  2. Use an online verification tool or the manual commands below for Windows/macOS.

  3. Compare the generated checksum with the CloudExtend-provided value.

    • If they match → your file is valid.

    • If they do NOT match → re-download the file.

    • If mismatches persist, contact CloudExtend support.

Option 1: Verify MD5 Checksum Online (Easiest)

Upload your file to a trusted online MD5 checker such as:

These tools generate the MD5 checksum for you, no commands needed.

If you prefer to manually validate the values keep reading.

Option 2: Verify MD5 Checksum Manually (Windows)

Windows 10

  • Open Windows PowerShell Utility/App

  • Execute the following command by updating the path to the downloaded registry file.

    Get-FileHash <filepath> -Algorithm MD5

    Eg:- Get-FileHash C:\Users\user1\Downloads\samesitepolicy-edge.reg -Algorithm MD5

  • Compare the output with the provided value in this article to verify the integrity.

Option 3: Verify MD5 Checksum Manually (macOS)

  • Open Terminal.app (Open spotlight by pressing Command + Space and type Terminal)

  • Change directory (cd) to the location where you have downloaded the registry file.

    • Eg: Downloads directory cd /Users/<username>/Downloads/

  • Run md5 command for the file downloaded (chrome or edge)

    md5 samesitepolicy-chrome91+.reg

    md5 samesitepolicy-edge.reg

Example Verification

When using the (samesitepolicy-chrome91+.reg) file the key provided by CloudExtend () should match the one generated from above output.
​

If CloudExtend provided this checksum:

0ad3e986030a505ce8f0e000c2785e2c

And your MD5 output matches exactly, your file is valid and safe to use.

If it does not match, re-download the file and verify again.
