However, security can be implemented so safe data exchange can still occur even if you are using an otherwise insecure transfer process.

  • There are many ZIP tools, including PKZIP, WinZIP, and 7-ZIP, each of which support creating encrypted archives. PGP and ZIP utilities are available for most platforms.
  • AxCrypt is a standalone Windows based AES encryption tool.
