release checksum file not created by sha256sum

[qrkourier]

Is there a particular Windows checksum checker the checksum file is intended for? I wasn't able to use it with sha256sum because it's not created by sha256sum, so it was necessary to manually compare the checksum by opening the file and ignoring the stray characters.

kbingham@oryp3win10:~$ cd /mnt/c/Users/w/Downloads/

kbingham@oryp3win10:/mnt/c/Users/w/Downloads$ sha256sum --check ./Ziti.Desktop.Edge.Client-2.1.16.exe.sha256
sha256sum: ./Ziti.Desktop.Edge.Client-2.1.16.exe.sha256: no properly formatted SHA256 checksum lines found

kbingham@oryp3win10:/mnt/c/Users/w/Downloads$ cat ./Ziti.Desktop.Edge.Client-2.1.16.exe.sha256
