function Get-CredentialStoreItem { <# .SYNOPSIS Returns the Credential from a given remote host item. .DESCRIPTION Return the credential as PSCredential object. .PARAMETER RemoteHost Specify the host, for which you would like to change the credentials. .PARAMETER Identifier Provide a custom identifier to the given remote host key. This enables you to store multiple credentials for a single remote host entry. For example ad/sys1, ftp/sys1, mssql/sys1 .PARAMETER Path Define a custom path to a shared CredentialStore. .PARAMETER Shared Switch to shared mode with this param. This enforces the command to work with a shared CredentialStore which can be decrypted across systems. .INPUTS [None] .OUTPUTS [System.Management.Automation.PSCredential] .EXAMPLE $myCreds = Get-CredentialStoreItem -Path "C:\TMP\mystore.json" -RemoteHost "esx01.myside.local" .NOTES - File Name : Get-CredentialStoreItem.ps1 - Author : Messing - marco.blessing@googlemail.com - Requires : .LINK https://github.com/OCram85/PSCredentialStore #> [CmdletBinding(DefaultParameterSetName = "Private")] [OutputType([PSCredential])] param( [Parameter(Mandatory = $true, ParameterSetName = "Shared")] [Parameter(Mandatory = $true, ParameterSetName = "Private")] [ValidateNotNullOrEmpty()] [string]$RemoteHost, [Parameter(Mandatory = $false, ParameterSetName = "Shared")] [Parameter(Mandatory = $false, ParameterSetName = "Private")] [ValidateNotNullOrEmpty()] [string]$Identifier, [Parameter(Mandatory = $true, ParameterSetName = "Shared")] [switch]$Shared, [Parameter(Mandatory = $false, ParameterSetName = "Shared")] [ValidateNotNullOrEmpty()] [string]$Path ) begin { # Set the CredentialStore for private, shared or custom mode.
