Is there a command line utility to extract the certificate thumbprint?
Get thumbprint directly from file .cer
const certpath = "\\host\res\something.cer"
dim objStdOut
dim strLine, resString
set objStdOut = CreateObject("WScript.Shell").Exec("certutil " & certpath).StdOut
while not objStdOut.AtEndOfStream
strLine = objStdOut.ReadLine
if InStr(strLine, "(sha1)") > 0 then resString = trim(split(strLine, ":")(1))
wend
wscript.echo resString
Old, but maybe this will help someone. Put the following in a powershell script(.ps1) and run it. It will print the thumb to the screen. watch the word wrap in my paste.
$computerName = $Env:Computername
$domainName = $Env:UserDnsDomain
write-host "CN=$computername.$domainname"
$getThumb = Get-ChildItem -path cert:\LocalMachine\My | where { $_.Subject -match "CN\=$Computername\.$DomainName" }
$getThumb.thumbprint
In my case I could not use PowerShell, so I wrote this script to run with cscript.exe that will get you the thumb using a Regular Expression.
If WScript.Arguments.Count() = 0 Then
WScript.Echo "Domain name to search for must be specified as first parameter."
WScript.Quit 1
End If
domain = WScript.Arguments.Item(0)
Set objShell = WScript.CreateObject ("WScript.shell")
' Get all certificate information in store.
Set objCert = objShell.Exec("certutil -store my")
certOutput = ""
Do While objCert.Status = 0
WScript.Sleep 10
Do While Not objCert.StdOut.AtEndOfStream
certOutput = certOutput & objCert.StdOut.ReadLine & vbNewLine
Loop
Loop
' Capture thumb for specified certificate using Regex.
Set thumbRegex = New RegExp
thumbRegex.Pattern = "Subject:\s+CN=" & domain & "\s*\n.*\n.*\nCert\sHash\(sha1\):\s+(.*)"
thumbRegex.IgnoreCase = True
thumbRegex.Global = False
' Verify match and trim out white space.
Set match = thumbRegex.Execute(certOutput)
result = ""
If match.Count > 0 Then
result = match.Item(0).Submatches(0)
result = Replace(result, " ", "")
WScript.Echo result
Else
WScript.Echo "The certificate for """ & domain & """ was not found."
WScript.Quit 2
End If
Direct from command-line for a .cer file that isn't installed, and removes the embedded spaces (can probably be improved):
certutil.exe <mycert>.cer | findstr /c:"Cert Hash(sha1)" | for /f "tokens=3-22" %f in ('more') do @echo %f%g%h%i%j%k%l%m%n%o%p%q%r%s%t%u%v%w%x%y
