Using SHA

After you downloaded the ISO, you also need to download the SHA file which you can find under the header “Verify your download” on the product page. Follow these instructions to verify your download with SHA.


You have saved the ISO and the SHA file in the same directory and you have not renamed the ISO. Open a terminal and execute the following command:

sha256sum -c *.sha256

This will check all .sha256 files in the current directory. The ISO has been downloaded correctly when the output indicates "OK", for example:

solydk_9_64_201803.iso: OK

If there is "NOK" in the output, you must download the ISO again and repeat this verification.


Windows users can use HashTab.
