README

wnfs-go

go language implementation of the fission web-native file system, using the typescript implementation as a reference.

Development Status: Work-In-Progress

This repo is very much a work-in-progress, and doesn't yet produce proper WNFS data. Don't rely on this.

Security Status: Insecure

This repo has the beginnings of an implementation of a private, encrypted-at-rest filesystem. It is not finished and is not reliable for keeping your data secure. Don't use this to store private data until this message is removed.
