check MD5/SHA quick and easy!
Using “Get-FileHash” in Powershell:
Get-FileHash <FILE_PATH>-Algorithm SHA512 | Format-List
Using “certutil.exe“
certutil -hashfile <FILE_PATH>SHA512
Here’s a fancy script that uses “Get-FileHash“:
do { Clear-Host write-host "" write-host "" write-host " File Validator! " -ForegroundColor Green write-host "" write-host "" write-host " Drag file to this window and press enter! " write-host "" $checkFile = read-host Clear-Host write-host "" $checkFile = $checkFile.Replace('"','') Write-Host "Checking: $checkFile" write-host "" $Info = "Choose Hash:" $options = [System.Management.Automation.Host.ChoiceDescription[]] @("&MD5", "SHA&1", "SHA&256", "SHA&384", "SHA&512", "3&DES") [int]$defaultchoice = 1 $opt = $host.UI.PromptForChoice($Title , $Info , $Options,$defaultchoice) switch($opt) { 0 { Get-FileHash $checkFile -Algorithm MD5 | Format-List } 1 { Get-FileHash $checkFile -Algorithm SHA1 | Format-List } 2 { Get-FileHash $checkFile -Algorithm SHA256 | Format-List } 3 { Get-FileHash $checkFile -Algorithm SHA384 | Format-List } 4 { Get-FileHash $checkFile -Algorithm SHA512 | Format-List} 5 { Get-FileHash $checkFile -Algorithm MACTripleDES | Format-List } } pause } until ( $checkFile -match "exit" )
Here’s an option for PowerShell V3
#--- Powershell v3 #$md5 = New-Object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider #$hash = [System.BitConverter]::ToString($md5.ComputeHash([System.IO.File]::ReadAllBytes($checkFile))) #Write-Host $hash #Write-Host "" #pause
