+### Extracting pfSense Certificates (without private key)
+####
+# Redefine the $cfg string variable to point to a valid non encrypted pfSense XML configuration backup file.
+# You can also pass the command line FilePath parameter as path to the input XML cfg file.
+# [array]$listaC = .\ListadoPfsUsuarios <path_to_uncipher_pfsense_xml_config_file.xml>
+#
+# The csv export file <"$($env:userprofile)\Downloads\usuariospfsense.csv"> bill by created/rewrited
+# every time you exececute the script
+# 
+# Also, you will obtain the $listaC variable, an object plain of data about the certificates and related users.
+# You can filter $listaC as you want after the first excecution.
+
+# This script will return the CA certificates, Server certificates, User certificates (used or not used) and
+# duplicated Serial Number Certificates.
