Welcome to the TFC wiki.

TFC is not your standard encrypted messaging tool that is run on your everyday computer. For such environments, there already exists more convenient tools, e.g. Ricochet, Signal desktop client and Tor Messenger. TFC can be tested on such a system, but without the security features that sets it apart from all the other tools.

TFC is the first messaging tool designed to be run in hardware configuration that provides strong endpoint security. This security can not be obtained without the inconvenience of investing in hardware and learning how to operate the system securely. As Bruce Schneier puts it, security is a process, not a product. There's a number of caveats, risks and warnings, so make sure to read the wiki throughly before installing.
