Check SHA256 (256-bit) Checksums

Using sha256sum command in Linux you can check SHA 256 Bit Checksum. Below are the steps.

1. Suppose you have setup.exe file then you can check the SHA 256 Bit Checksum as below.

   # sha256sum setup.exe
   b7e8dabcaf825a65085564a63791355f37a18d5df5b3da71d4c0002ee40522f6 setup.exe

   The text “b7e8dabcaf825a65085564a63791355f37a18d5df5b3da71d4c0002ee40522f6” is SHA 256 Bit Checksum of setup.exe file.

2. If you have check sum of some downloaded file then you can verify integrity of the file as below.

   # echo 'b7e8dabcaf825a65085564a63791355f37a18d5df5b3da71d4c0002ee40522f6 setup.exe' | sha256sum --check
   setup.exe: OK

   If you get OK as response then the file is OK.

3. You can use this command to verify downloaded files.
