#region public functions function Select-FilesToSign() { <# .SYNOPSIS Produces a file that containing a list of files to be code signed. .DESCRIPTION Produces a file that containing a list of files to be code signed. Searches the provided root directory, and selects files based on regex pattern parameters, which do not already have a valid authenticode signature. .PARAMETER Path System.String; Required - The root path to begin searching for files to code sign. .PARAMETER Includes System.String; Optional - Default value is '.*' (matching everything). Each file which has a full path matching this regular expression pattern will be signed, if: 1. The file extension matches an extension Extensions 2. The file full name does not match the optional 'Excludes' pattern .PARAMETER Excludes System.String; Optional - Files with a full name matching this optional pattern will be excluded from code signing. .PARAMETER Extensions System.String; Optional - Comma-separated list of file extensions to include in search for files to sign. .PARAMETER OutputFileList System.String; Required - Full path for text file which will contain list of files that require an authenticode signature. .EXAMPLE # Searches C:\src\bin\Release, using default parameter values; # C:\files-to-sign.txt will be created. Any unsigned file with an extension # of .exe, .dll, .ocx, or .cab.
