In computing, Self-certifying File System (SFS) is a global and decentralized, distributed file system, while also providing transparent encryption of communications as well as authentication. The SFS client implements the network file system protocol for communicating with the operating system, and thus can work anywhere where NFS is supported.

The primary motivation behind the file system is to address the shortcomings of hardwired, administratively configured network file systems, and various remote file transfer protocols. For example, one could store all their files on a single remote server, and access the same files transparently from any location as if they were stored locally, without any special privileges or administrative cooperation. The file system will always be found in the same location, and is implicitly authenticated as its path includes the public-key fingerprint of the server. On Unix-like systems, are usually located at /sfs/location:hostID
