# Anonymous Github
Anonymous Github is a system that helps anonymize Github repositories for double-anonymous paper submissions. A public instance of Anonymous Github is hosted at https://anonymous.4open.science/.
![screenshot](public/imgs/screenshot.png)
Anonymous Github anonymizes the following:
- Github repository owner, organization, and name
- File and directory names
- File contents of all extensions, including markdown, text, Java, etc.
## Usage
### Public instance
**https://anonymous.4open.science/**
### CLI
This CLI tool allows you to anonymize your GitHub repositories locally, generating an anonymized zip file based on your configuration settings.
```bash
# Install the Anonymous GitHub CLI tool
npm install -g @tdurieux/anonymous_github
# Run the Anonymous GitHub CLI tool
anonymous_github
```
### Own instance
#### 1. Clone the repository
```bash
git clone https://github.com/tdurieux/anonymous_github/
cd anonymous_github
npm i
```
#### 2. Configure the GitHub token
Create a `.env` file with the following contents:
```env
GITHUB_TOKEN=<GITHUB_TOKEN>
CLIENT_ID=<CLIENT_ID>
CLIENT_SECRET=<CLIENT_SECRET>
PORT=5000
DB_USERNAME=
DB_PASSWORD=
AUTH_CALLBACK=http://localhost:5000/github/auth,
```
- `GITHUB_TOKEN` can be generated here: https://github.com/settings/tokens/new with `repo` scope.
- `CLIENT_ID` and `CLIENT_SECRET` are the tokens are generated when you create a new GitHub app https://github.com/settings/applications/new.
- The callback of the GitHub app needs to be defined as `https://<host>/github/auth` (the same as defined in AUTH_CALLBACK).
#### 3. Start Anonymous Github server
```bash
docker-compose up -d
```
#### 4. Go to Anonymous Github
Go to http://localhost:5000. By default, Anonymous Github uses port 5000. It can be changed in `docker-compose.yml`. I would recommand to put Anonymous GitHub behind ngnix to handle the https certificates.
## What is the scope of anonymization?
In double-anonymous peer-review, the boundary of anonymization is the paper plus its online appendix, and only this, it's not the whole world. Googling any part of the paper or the online appendix can be considered as a deliberate attempt to break anonymity ([explanation](https://www.monperrus.net/martin/open-science-double-blind))
## How does it work?
Anonymous Github either downloads the complete repository and anonymizes the content of the file or proxies the request to GitHub. In both cases, the original and anonymized versions of the file are cached on the server.
## Related tools
[gitmask](https://www.gitmask.com/) is a tool to anonymously contribute to a Github repository.
[blind-reviews](https://github.com/zombie/blind-reviews/) is a browser add-on that enables a person reviewing a GitHub pull request to hide identifying information about the person submitting it.

## Why
Double-anonymous review asks you to anonymize the artifact behind your paper — the code and data — exactly like the paper itself. Doing that by hand (owner, organization, repository name, logins, and every mention buried in the files) is tedious and easy to get wrong. Anonymous GitHub does it for you and serves the result behind a shareable link.
A free public instance is available at **[anonymous.4open.science](https://anonymous.4open.science/)**.
## What it anonymizes
- The GitHub **owner, organization, and repository name**
- **File and directory names**
- **File contents** of every extension (Markdown, text, source code, …), replacing a configurable list of terms
## Usage
### Public instance
Just open **[anonymous.4open.science](https://anonymous.4open.science/)**, paste your repository URL, add the terms to hide, and share the generated link.
### CLI
Anonymize a repository locally and produce an anonymized zip:
```bash
npm install -g @tdurieux/anonymous_github
anonymous_github
```
## Self-hosting
<details>
<summary>Run your own instance with Docker</summary>
**1. Clone and install**
```bash
git clone https://github.com/tdurieux/anonymous_github/
cd anonymous_github
npm i
```
**2. Configure GitHub access** — create a `.env` file:
```env
GITHUB_TOKEN=<GITHUB_TOKEN>
CLIENT_ID=<CLIENT_ID>
CLIENT_SECRET=<CLIENT_SECRET>
PORT=5000
DB_USERNAME=
DB_PASSWORD=
AUTH_CALLBACK=http://localhost:5000/github/auth
```
- `GITHUB_TOKEN` — create one at <https://github.com/settings/tokens/new> with the `repo` scope.
- `CLIENT_ID` / `CLIENT_SECRET` — from a new GitHub App at <https://github.com/settings/applications/new>.
- The App's callback must be `https://<host>/github/auth` (matching `AUTH_CALLBACK`).
**3. Start the server**
```bash
docker-compose up -d
```
**4. Open** <http://localhost:5000>. The port can be changed in `docker-compose.yml`; putting Anonymous GitHub behind nginx is recommended for HTTPS.

## Scope of anonymization
In double-anonymous review, the boundary of anonymization is **the paper plus its online appendix — and only that**. Googling part of the paper or appendix to reveal authorship is considered a deliberate attempt to break anonymity ([explanation](https://www.monperrus.net/martin/open-science-double-blind)).
## How it works
Anonymous GitHub either downloads the full repository and anonymizes each file, or proxies requests to GitHub on the fly. In both cases the original and anonymized versions are cached on the server, so even large repositories stay responsive.
