Yet Another Standardfile Implementation in Go

This is a 100% Golang implementation of the Standard File protocol. It aims to be portable and lightweight.

Running your own server

You can run your own Standard File server, and use it with any SF compatible client (like Standard Notes). This allows you to have 100% control of your data. This server implementation is built with Go and can be deployed in seconds.

Client library

Go to pgk/libsf for more details. https://godoc.org/github.com/mdouchement/standardfile/pkg/libsf

It is an alternative to https://github.com/jonhadfield/gosn

SF client

go run cmd/sfc/main.go -h

Terminal UI client:

Requirements

• Golang 1.11.x (Go Modules)

Technologies / Frameworks

• Cobra
• Echo
• BoltDB + Storm Toolkit
• Gowid

Differences with reference implementation

Drop legacy support for clients which hardcoded the "api" path to the base url (iOS)

Permalink

Drop the POST request done on Extensions (backups too)

Permalink

This feature is pretty undocumented and I feel uncomfortable about the outgoing traffic from my server on unknown URLs.

Drop V1 support

All stuff used in v1 and not in v2 nor v3

JWT revocation strategy after password update

Reference implementation use a pw_hash claim to check if the user has changed their pw and thus forbid them from access if they have an old jwt.

---

Here we will revoke JWT based on its iat claim and User.PasswordUpdatedAt field. Looks more safer than publicly expose any sort of password stuff. See internal/server/middlewares/current_user.go

Session use PASETO tokens instead of random tokens

Here we will be using PASETO to strengthen authentication to ensure that the tokens are issued by the server.

Not implemented (yet)

• 2FA (aka verify_mfa)
• Postgres if a more stronger database is needed
• A console for admin usage
