Incorrect Commands for Verifying Checksums on Windows 10
Last modified: 2016-02-02 09:30:53 EST
Description of problem:
I tried the instructions for verifying checksums on Windows (section 3.3.1) but ran into a problem.
Version-Release number of selected component (if applicable):
Fedora 23 iso download, Windows 10 computer
Follow the instructions detailed in section 3.3.1 of the install-guide on a Windows 10 computer.
Steps to Reproduce:
1. Download the Fedora checksum file
2. Open a powershell session
3. Change to the directory containing the checksum file
4. Run the following commands:
> $image = "Fedora-Server-DVD-x86_64-21.iso"
> $checksum_file = "Fedora-Server-21-x86_64-CHECKSUM"
> $sha256 = New-Object -TypeName System.Security.Cryptography.sha256CryptoServiceProvider
> $expected_checksum = ((Get-Content $checksum_file | Select-String -Pattern $image) -split " ").ToLower()
> echo "Expected Checksum: $expected_checksum"
The correct checksum is actually in the fourth and final position of the string after being split. I recommend replacing the  in the instructions with a [-1], assuming that you are able to recreate this problem. If not, let me know and I'll try to provide a more detailed report.
