    <#
    .SYNOPSIS
        Reads the complete content of the credential store and returns it as a new object.
 
    .DESCRIPTION
        The content is in a raw format. It means there is no transformation to the different credential types.

        Get-CredentialStoreItem.
 
    .PARAMETER Path
        Define a custom path to a shared CredentialStore.
 
    .PARAMETER Shared

        can be decrypted across systems.
 
    .INPUTS
        [None]
 
    .OUTPUTS
        [PSObject] Returns the credential store content as PSObject.
