Creates an in-memory assembly and module

creates an in-memory module that can be passed to the 'enum',
'struct', and Add-Win32Type functions.

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 EntryPoint

The DLL export function name. This argument should be specified if the
specified function name is different than the name of the exported
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.

<#
.SYNOPSIS

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

Author: Matthew Graeber (@mattifestation)
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

$ImageDosSignature = psenum $Mod PE.IMAGE_DOS_SIGNATURE UInt16 @{
    DOS_SIGNATURE =    0x5A4D
    OS2_SIGNATURE =    0x454E
    OS2_SIGNATURE_LE = 0x454C
    VXD_SIGNATURE =    0x454C
}

$ImageDosHeader = struct $Mod PE.IMAGE_DOS_HEADER @{
    e_magic =    field 0 $ImageDosSignature
    e_cblp =     field 1 UInt16
    e_cp =       field 2 UInt16
    e_crlc =     field 3 UInt16
    e_cparhdr =  field 4 UInt16
    e_minalloc = field 5 UInt16
    e_maxalloc = field 6 UInt16
    e_ss =       field 7 UInt16
    e_sp =       field 8 UInt16
    e_csum =     field 9 UInt16
    e_ip =       field 10 UInt16
    e_cs =       field 11 UInt16
    e_lfarlc =   field 12 UInt16
    e_ovno =     field 13 UInt16
    e_res =      field 14 UInt16[] -MarshalAs @('ByValArray', 4)
    e_oemid =    field 15 UInt16
    e_oeminfo =  field 16 UInt16
    e_res2 =     field 17 UInt16[] -MarshalAs @('ByValArray', 10)
    e_lfanew =   field 18 Int32
}

# Example of using an explicit layout in order to create a union.
$TestUnion = struct $Mod TestUnion @{
    field1 = field 0 UInt32 0
    field2 = field 1 IntPtr 0
} -ExplicitLayout

function CloseHandle
{
    <#
    .SYNOPSIS

    Closes an open object handle.

    .DESCRIPTION

    The CloseHandle function closes handles to the following objects:
    - Access token
    - Communications device
    - Console input
    - Console screen buffer
    - Event
    - File
    - File mapping
    - I/O completion port
    - Job
    - Mailslot
    - Memory resource notification
    - Mutex
    - Named pipe
    - Pipe
    - Process
    - Semaphore
    - Thread
    - Transaction
    - Waitable timer
    
    The documentation for the functions that create these objects indicates that CloseHandle should be used when you are finished with the object, and what happens to pending operations on the object after the handle is closed. In general, CloseHandle invalidates the specified object handle, decrements the object's handle count, and performs object retention checks. After the last handle to an object is closed, the object is removed from the system. 

    .PARAMETER Handle

    A valid handle to an open object.

function DuplicateToken
{
    <#
    .SYNOPSIS

    The DuplicateToken function creates a new access token that duplicates one already in existence.

    .DESCRIPTION

    The DuplicateToken function creates an impersonation token, which you can use in functions such as SetThreadToken and ImpersonateLoggedOnUser. The token created by DuplicateToken cannot be used in the CreateProcessAsUser function, which requires a primary token. To create a token that you can pass to CreateProcessAsUser, use the DuplicateTokenEx function.

    .PARAMETER TokenHandle

    A handle to an access token opened with TOKEN_DUPLICATE access.

function ImpersonateLoggedOnUser
{
    <#
    .SYNOPSIS

    The ImpersonateLoggedOnUser function lets the calling thread impersonate the security context of a logged-on user. The user is represented by a token handle.

    .DESCRIPTION

    The impersonation lasts until the thread exits or until it calls RevertToSelf.
    
    The calling thread does not need to have any particular privileges to call ImpersonateLoggedOnUser.
    
    If the call to ImpersonateLoggedOnUser fails, the client connection is not impersonated and the client request is made in the security context of the process. If the process is running as a highly privileged account, such as LocalSystem, or as a member of an administrative group, the user may be able to perform actions they would otherwise be disallowed. Therefore, it is important to always check the return value of the call, and if it fails, raise an error; do not continue execution of the client request.
    
    All impersonate functions, including ImpersonateLoggedOnUser allow the requested impersonation if one of the following is true:
    - The requested impersonation level of the token is less than SecurityImpersonation, such as SecurityIdentification or SecurityAnonymous.
    - The caller has the SeImpersonatePrivilege privilege.
    - A process (or another process in the caller's logon session) created the token using explicit credentials through LogonUser or LsaLogonUser function.
    - The authenticated identity is same as the caller.
    
    Windows XP with SP1 and earlier:  The SeImpersonatePrivilege privilege is not supported.

    .PARAMETER TokenHandle

    A handle to a primary or impersonation access token that represents a logged-on user. This can be a token handle returned by a call to LogonUser, CreateRestrictedToken, DuplicateToken, DuplicateTokenEx, OpenProcessToken, or OpenThreadToken functions. If hToken is a handle to a primary token, the token must have TOKEN_QUERY and TOKEN_DUPLICATE access. If hToken is a handle to an impersonation token, the token must have TOKEN_QUERY and TOKEN_IMPERSONATE access.

function LsaCallAuthenticationPackage
{
    <#
    .SYNOPSIS

    The LsaCallAuthenticationPackage function is used by a logon application to communicate with an authentication package.
    
    This function is typically used to access services provided by the authentication package.

    .DESCRIPTION

    Logon applications can call LsaCallAuthenticationPackage to communicate with an authentication package. There are several reasons why an application may do this:
    
    - To implement multiple-message authentication protocols, such as the NTLM Challenge-Response protocol.
    - To pass state change information to the authentication package. For example, the NTLM might notify the MSV1_0 package that a previously unreachable domain controller is now reachable. The authentication package would then re-logon any users logged on to that domain controller.
    
    Typically, this function is used to exchange information with a custom authentication package. This function is not needed by an application that is using one of the authentication packages supplied with Windows, such as MSV1_0 or Kerberos.
    
    You must call LsaCallAuthenticationPackage to clean up PKINIT device credentials for LOCAL_SYSTEM and NETWORK_SERVICE. When there is no PKINIT device credential, a successful call does no operation. When there is a PKINIT device credential, a successful call cleans up the PKINIT device credential so that only the password credential remains.

function LsaConnectUntrusted
{
    <#
    .SYNOPSIS

    The LsaConnectUntrusted function establishes an untrusted connection to the LSA server.

    .DESCRIPTION

    LsaConnectUntrusted returns a handle to an untrusted connection; it does not verify any information about the caller. The handle should be closed using the LsaDeregisterLogonProcess function.
    
    If your application simply needs to query information from authentication packages, you can use the handle returned by this function in calls to LsaCallAuthenticationPackage and LsaLookupAuthenticationPackage.
    
    Applications with the SeTcbPrivilege privilege may create a trusted connection by calling LsaRegisterLogonProcess.

function RevertToSelf
{
    <#
    .SYNOPSIS

    The RevertToSelf function terminates the impersonation of a client application.

    .DESCRIPTION

    A process should call the RevertToSelf function after finishing any impersonation begun by using the DdeImpersonateClient, ImpersonateDdeClientWindow, ImpersonateLoggedOnUser, ImpersonateNamedPipeClient, ImpersonateSelf, ImpersonateAnonymousToken or SetThreadToken function.
    
    An RPC server that used the RpcImpersonateClient function to impersonate a client must call the RpcRevertToSelf or RpcRevertToSelfEx to end the impersonation.
    
    If RevertToSelf fails, your application continues to run in the context of the client, which is not appropriate. You should shut down the process if RevertToSelf fails.
