function Set-CredentialStoreItem { <# .SYNOPSIS Changes the credentials for the given remote host in the store. .DESCRIPTION .PARAMETER Path Define the store in which your given host entry already exists. .PARAMETER RemoteHost Specify the host you for which you would like to change the credentials. .PARAMETER Identifier Defaults to "". Specify a string, which separates two CredentialStoreItems for the same hostname. .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 [None] .EXAMPLE Set-CredentialStoreItem -Path "C:\TMP\mystore.json" -RemoteHost "esx01.myside.local" Set-CredentialStoreItem -Path "C:\TMP\mystore.json" -RemoteHost "esx01.myside.local" -Identifier svc .NOTES ``` File Name : Set-CredentialStoreItem.ps1 Author : Marco Blessing - marco.blessing@googlemail.com Requires : ``` .LINK https://github.com/OCram85/PSCredentialStore #> [CmdletBinding(DefaultParameterSetName = "Private")] param( [Parameter(Mandatory = $true, ParameterSetName = "Private")] [Parameter(Mandatory = $true, ParameterSetName = "Shared")] [string]$RemoteHost, [Parameter(Mandatory = $false, ParameterSetName = "Private")] [Parameter(Mandatory = $false, ParameterSetName = "Shared")] [string]$Identifier, [Parameter(Mandatory = $false, ValueFromPipeline = $true)] [ValidateNotNullOrEmpty()] [PSCredential]$Credential, [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.
