Hash values are useful for verifying the integrity of data sent through insecure channels. This article will help you to verify the data integrity of the Sonic OS firmware images downloaded from the Mysonicwall account/Other sources.
In several situations, we might be receiving the firmware images of the SonicWall Network security appliances from sources other than Mysonicwall.com and have concerns about the integrity of the firmware images.
*For all versions of Sonic OS firmwareimages
Login to your Mysonicwall account and navigate to Download center |By ProductLine
Please search for the Product Name and Firmware Version.
Copy the checksum value of the Firmware Image on the window.
Please download any Hash verifier tool from the web or you may use the inbuilt Hash checker tool in Windows PowerShell.
Compare the Last Hash value against the original checksum value. If the Hash values are the same, the data's integrity is preserved and no changes are made to the firmware image.
