  • /in: the PowerShell credentials .xml file
  • /password: the password to use to decrypt the PSCredentials
  • /masterkey: the masterkey to use for decryption. It can be obtained through sekurlsa::dpapi.
  • /unprotect: displays the decryption results on screen

{% hint style="info" %} In the example above, the .xml PSCredential file for decryption was previously created by the same user, hence the absence of the /password or /masterkey argument, which would be needed when attempting to decrypt .xml PSCredentials of a different user. {% endhint %}
