Powershell and keytool.exe RRS feed

  • Question

  • Hi,

    1. I need testing if a certificate is already existing in cacerts.  I tested the below commandline but got Nothing of value...

    $ret=start-process -FilePath "C:\Program Files (x86)\Java\jre1.8.0_201\bin\keytool.exe" -ArgumentList "-list -v -keystore C:\Program Files (x86)\Java\jre1.8.0_201\lib\security\cacerts" - passthru

    Is it an easy way to test a certificate presence in cacerts?

    2. I am looking to push our organisation certificate inside all cacerts on all computers. Somebody already did that with Scripting?

    Thanks,

  • Hi,

    My first question is using PowerShell to run a commandline and I am looking to find a way to gather data in a PowerShell variable. So I am looking to find a way with PowerShell.

    Thanks,

  • To return any output from an external command just assign it to a variable.

    Your code already does that using the $ret" variable. That is all you can do.

  • You may need t add "-NoNewWindow".

    Also you don't need Start-Process or "PassThru"

    ${env:ProgramFiles(x86)}\Java\jre1.8.0_201\bin\keytool.exe -list -v -keystore "C:\Program Files (x86)\Java\jre1.8.0_201\lib\security\cacerts"

  • Hi,

    Your commandline is not working as there are variables and string. Why not using start-process?

    thanks,

  • Then do it this way:

    & "${env:ProgramFiles(x86)}\Java\jre1.8.0_201\bin\keytool.exe -list -v -keystore `"C:\Program Files (x86)\Java\jre1.8.0_201\lib\security\cacerts`""

  • Hi,

    When running only the first part of the commandline (they part of the keytool) without any parameters then I am seeing it working as it is asking me more parameters. As soon as I put the parameters part I get the below error.

    & "${env:ProgramFiles(x86)}\Java\jre1.8.0_201\bin\keytool.exe -list -v -keystore `"C:\Program Files (x86)\Java\jre1.8.0_201\lib\security\cacerts`""

  • The error tells you what is wrong.

    ObjectNotFound: (C:\Program File...curity\cacerts"

  • Hi,

    You were right. Wrong path for CACerts but even after changing the path:

    PS C:\WINDOWS\system32> & "${env:ProgramFiles(x86)}\Java\jre1.8.0_121\bin\keytool.exe -list -v -keystore `"C:\Program Files (x86)\Java\jre1.8.0_121\lib\security\cacerts`""
    & : Le terme «C:\Program Files (x86)\Java\jre1.8.0_121\bin\keytool.exe -list -v -keystore "C:\Program Files (x86)\Java\jre1.8.0_121\lib\security\cacerts"» n'est pas reconnu comme nom 
    d'applet de commande, fonction, fichier de script ou programme exécutable. Vérifiez l'orthographe du nom, ou si un chemin d'accès existe, vérifiez que le chemin d'accès est correct et 
    réessayez.
    Au caractère Ligne:1 : 3
    + & "${env:ProgramFiles(x86)}\Java\jre1.8.0_121\bin\keytool.exe -list -v -keystore ...
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        + CategoryInfo          : ObjectNotFound: (C:\Program File...curity\cacerts":String) [], CommandNotFoundException
        + FullyQualifiedErrorId : CommandNotFoundException

    I double checked the path for the keytool and cacerts. Both are correct now.

  • Then try it like this.

    & 'C:\"Program Files (x86)"\Java\jre1.8.0_121\bin\keytool.exe -list -v -keystore "C:\Program Files (x86)\Java\jre1.8.0_121\lib\security\cacerts"'

  • Hi,

    OK this is working:

    $ret=& "C:\Program Files (x86)\Java\jre1.8.0_121\bin\keytool.exe" -storepass changeit -list -v -keystore "C:\Program Files (x86)\Java\jre1.8.0_121\lib\security\cacerts"

    How may I find a particular string in $ret

    For each ($rret in $ret) {

    ...

    }

    No faster way?

  • You have to parse the string.

  • Hi,

    I need to test each line of the array? No faster way?

    Thanks,

  • Nope.  You need to learn how to parse. It is fundamental t programming.

  • you may try below 

    $x = '-keystore "' +  $env:java_Home + '\lib\security\cacerts"'

    $ret= (start-process "$env:Java_home\bin\keytool.exe" -ArgumentList '-list', '-v', '-storepass changeit', $x -PassThru -RedirectStandardOutput results.txt)

    Once it is executed, you will need to read thru the results.txt file to check the existence of certificate. 

    I haven't tested yet, but you may refer to https://www.powershellgallery.com/packages/PSCertUtils/0.2.1/Content/PSCertUtils.Java.psm1 to see if this helps.
