# Don’t forget to put your default cert thumbprint or path in a ModuleInfo file; it will work without that, but it will have to prompt you for a certificate.
# Description: Wrappers for the Get-AuthenticodeSignature and Set-AuthenticodeSignature which properly parse paths and don’t kill your pipeline and script when you hit a folder by accident, and default to using timestamping
#
#Requires -version 2.0
## Authenticode.psm1 updated for PowerShell 2.0 (with time stamping)
####################################################################################################
## Wrappers for the Get-AuthenticodeSignature and Set-AuthenticodeSignature cmdlets
## These properly parse paths, so they don't kill your pipeline and script if you include a folder
##
## Usage:
## ls | Get-AuthenticodeSignature
## Get all the signatures
##
## ls | Select-AuthenticodeSigned -Mine -Broken | Set-AuthenticodeSignature
## Re-sign anything you signed before that has changed
##
## ls | Select-AuthenticodeSigned -NotMine -ValidOnly | Set-AuthenticodeSignature
## Re-sign scripts that are hash-correct but not signed by me or by someone trusted
##
####################################################################################################
## History:
## 2.1 - Added some extra exports and aliases, and included my Start-AutoSign script...
## 2.0 - Updated to work with PowerShell 2.0 RTM and add -TimeStampUrl support
## 1.7 - Modified the reading of certs to better support people who only have one :)
## 1.6 - Converted to work with CTP 3, and added function help comments
## 1.5 - Moved the default certificate setting into the module info Authenticode.psd1 file
## Note: If you get this off PoshCode, you'll have to create it yourself, see below:
## 1.4 - Moved the default certificate setting into an external psd1 file.
## 1.3 - Fixed some bugs in If-Signed and renamed it to Select-AuthenticodeSigned
## - Added -MineOnly and -NotMineOnly switches to Select-AuthenticodeSigned
## 1.2 - Added a hack workaround to make it appear as though we can sign and check PSM1 files
## It's important to remember that the signatures are NOT checked by PowerShell yet...
## 1.1 - Added a filter "If-Signed" that can be used like: ls | If-Signed
## - With optional switches: ValidOnly, InvalidOnly, BrokenOnly, TrustedOnly, UnsignedOnly
## - commented out the default Certificate which won't work for "you"
## 1.0 - first working version, includes wrappers for Get and Set

## You should set the location to your default signing certificate. The permanent way to do that is
## to modify (or create) the .psd1 file to set the PrivateData member variable. Otherwise you'll be
## prompted to provide a cert path whenever you try to sign a script without passing a certificate.
##
## The PrivateData variable should point at your code-signing certificate either with a full path
## or with the THUMBPRINT of a certificate you have available in your Cert:\CurrentUser\My\ provider
##
## EG:
## 4F8842037D878C1FCDC6FD1313B200449716C353
## OR:
## "Cert:\CurrentUser\My\4F8842037D878C1FCDC6FD1313B200449716C353"
## OR a file name:
## "C:\Users\Joel\Documents\WindowsPowerShell\PoshCerts\Joel-Bennett_Code-Signing.pfx"
##
## The simplest thing is to just update the PSD1
##
## New-ModuleManifest .\Authenticode.psd1 -Nested .\Authenticode.psm1 `
## -Author "" -COmpany "" -Copy "" -Desc "" `
## -Types @() -Formats @() -RequiredMod @() -RequiredAs @() -Other @() `

function Test-AuthenticodeSignature {
<#.SYNOPSIS
Tests a script signature to see if it is valid, or at least unaltered.
.DESCRIPTION
The Test-AuthenticodeSignature function processes the output of Get-AuthenticodeSignature to determine if it
is Valid, OR **unaltered** and signed by the user's certificate
.NOTES
Test-AuthenticodeSignature returns TRUE even if the root CA certificate can't be verified, as long as the signing certificate's thumbnail matches the one specified by Get-UserCertificate.
.EXAMPLE
ls *.ps1 | Get-AuthenticodeSignature | Where {Test-AuthenticodeSignature $_}
To get the signature reports for all the scripts that we consider safely signed.
.EXAMPLE
ls | ? { gas $_ | Test-AuthenticodeSignature }
List all the valid signed scripts (or scripts signed by our cert)
.INPUTTYPE
System.Management.Automation.Signature
.PARAMETER Signature
Specifies the signature object to test. This should be the output of Get-AuthenticodeSignature.
.PARAMETER ForceValid
Switch parameter, forces the signature to be valid -- otherwise, even if the certificate chain can't be verified, we will accept the cert which matches the "user" certificate (see Get-UserCertificate).
Aliases Valid
.RETURNVALUE
Boolean value representing whether the script's signature is valid, or YOUR certificate

function Set-AuthenticodeSignature {
<#.SYNOPSIS
Adds an Authenticode signature to a Windows PowerShell script or other file.
.DESCRIPTION
The Set-AuthenticodeSignature function adds an Authenticode signature to any file that supports Subject Interface Package (SIP).
In a Windows PowerShell script file, the signature takes the form of a block of text that indicates the end of the instructions that are executed in the script. If there is a signature in the file when this cmdlet runs, that signature is removed.
.NOTES
After the certificate has been validated, but before a signature is added to the file, the function checks the value of the $SigningApproved preference variable. If this variable is not set, or has a value other than TRUE, you are prompted to confirm the signing of the script.
When specifying multiple values for a parameter, use commas to separate the values. For example, "<parameter-name> <value1>, <value2>".
.EXAMPLE
ls *.ps1 | Set-AuthenticodeSignature -Certificate $Certificate
To sign all of the files with the specified certificate
.EXAMPLE
ls *.ps1,*.psm1,*.psd1 | Get-AuthenticodeSignature | Where {!(Test-AuthenticodeSignature $_ -Valid)} | gci | Set-AuthenticodeSignature
List all the script files, and get and test their signatures, and then sign all of the ones that are not valid, using the user's default certificate.
.INPUTTYPE
String. You can pipe a file path to Set-AuthenticodeSignature.
.PARAMETER FilePath
Specifies the path to a file that is being signed.
Aliases Path, FullName
.PARAMETER Certificate
Specifies the certificate that will be used to sign the script or file. Enter a variable that stores an object representing the certificate or an expression that gets the certificate.
To find a certificate, use Get-PfxCertificate or use the Get-ChildItem cmdlet in the Certificate (Cert:) drive. If the certificate is not valid or does not have code-signing authority, the command fails.
.PARAMETER Force
Allows the cmdlet to append a signature to a read-only file. Even using the Force parameter, the cmdlet cannot override security restrictions.
.Parameter HashAlgorithm
Specifies the hashing algorithm that Windows uses to compute the digital signature for the file. The default is SHA1, which is the Windows default hashing algorithm.
Files that are signed with a different hashing algorithm might not be recognized on other systems.
.PARAMETER IncludeChain
Determines which certificates in the certificate trust chain are included in the digital signature. "NotRoot" is the default.
Valid values are:
-- Signer: Includes only the signer's certificate.
-- NotRoot: Includes all of the certificates in the certificate chain, except for the root authority.
--All: Includes all the certificates in the certificate chain.
.PARAMETER TimestampServer
Uses the specified time stamp server to add a time stamp to the signature. Type the URL of the time stamp server as a string.
Defaults to Verisign's server: http://timestamp.verisign.com/scripts/timstamp.dll
The time stamp represents the exact time that the certificate was added to the file. A time stamp prevents the script from failing if the certificate expires because users and programs can verify that the certificate was valid atthe time of signing.
