Windows also has a built-in command-line tool to check hashes.
First, using Windows Explorer, navigate to the folder to which you downloaded
shift + right-click somewhere on the background (don't select any files) and select
Open command window here.
You'll be presented with the console which will start in the same working folder so it'll make the following steps easier.
certutil -hashfile monero-win-x64-v0.10.3.0.zip SHA256
You'll see an output like:
SHA256 hash of file monero-win-x64-v0.10.3.0.zip: 37 a5 7d 1b e8 1b 61 19 ac 06 d3 f6 37 b4 c5 6f c6 25 f3 e7 90 f3 49 1c 1b dc a4 d6 29 02 bf 13 CertUtil: -hashfile command completed successfully.
which you can compare against the one published on getmonero.org
Download and install the Quick Hash GUI
Open the program, select
SHA256 then select
file and find
monero-win-x64-v0.10.3.0.zip in your downloads folder
If you receive the following output you will know that the hash matches the GPG signed message listing the correct SHA256 sums
With Powershell Get-FileHash cmdlet:
PS> Get-FileHash monero-win-x64-v0.10.3.0.zip -Algorithm SHA256
The full check could be:
PS> '37a57d1be81b6119ac06d3f637b4c56fc625f3e790f3491c1bdca4d62902bf13' -eq >> (Get-FileHash monero-win-x64-v0.10.3.0.zip -Algorithm SHA256 | >> Select-Object -ExpandProperty Hash)
