OnionCat is an open source VPN-like application that allows users to securely connect over the Tor network. It provides a secure and private connection between two or more computers without the need for an intermediate server. Unlike traditional VPNs, OnionCat does not use encryption, but instead uses the Tor network to securely route traffic, making it an ideal solution for file sharing applications and software. OnionCat also provides a way for users to hide their IP address, allowing them to remain anonymous while sharing files. OnionCat is free to use, and is compatible with both Windows and Linux operating systems.
