# Example of using 'Get-FileHash' directly on a file:
#Get-FileHash "C:\example-directory-name\file-name.exe" -Algorithm SHA256

# Add file name with path to file here:
#$file = "C:\example-directory-name\file-name.exe" # *NOTE: Change this value and add the correct path to your file here.
$file = "C:path\to\file\file-name-here" # *NOTE: Change this value and add the correct path to your file here.

# Define the Algorithm Type here (SHA1, MD5, SHA256, SHA384, SHA512). We'll pass this value into the 'Get-FileHash' command:
$hashType = "SHA256"

# This command actually computes the file's hash value:
$hashParams = Get-FileHash $file -Algorithm $hashType

# Capture the above 3 values ($file, $hashType, $hashParams) and store in variable '$hashSourcefile:
$hashsourcefile = $hashParams

# Paste the hash value provided by the software vendor here. Usually provided on same page as file download.
# We will compare the computed value of the file to this hash value from the vendor
#$providedHash = "00000000000000000000000000000000000000000000000000000000000000000" # *NOTE: change this value, add the correct hash.
$providedHash = "00000000000000000000000000000000000000000000000000000000000000000" # *NOTE: change this value, add the correct hash.

# We will Compare the two hashe values below and see if they match:
