About Hanzo eSign

Signing documents digitally should be fast and easy and should be the best practice for every document signed worldwide. This is technically quite easy today, but it also introduces a new party to every signature: The signing tool providers. While this is not a problem in itself, it should make us think about how we want these providers of trust to work. Hanzo eSign aims to be the world's most trusted document-signing tool. This trust is built by empowering you to self-host Hanzo eSign and review how it works under the hood.

Join us in creating the next generation of open trust infrastructure.

Local Development

Requirements

To run Hanzo eSign locally, you will need

• Node.js (v22 or above)
• Postgres SQL Database
• Docker (optional)

Developer Quickstart

Note

: This is a quickstart for developers. It assumes that you have both docker and docker-compose installed on your machine.

Want to get up and running quickly? Follow these steps:

1. Fork this repository to your GitHub account.

After forking the repository, clone it to your local device by using the following command:

git clone https://github.com/<your-username>/hanzo-sign

2. Set up your .env file using the recommendations in the .env.example file. Alternatively, just run cp .env.example .env to get started with our handpicked defaults.

3. Run npm run dx in the root directory

   • This will spin up a postgres database and inbucket mailserver in a docker container.

4. Run npm run dev in the root directory

5. Want it even faster? Just use

npm run d

1. Fork this repository to your GitHub account.

After forking the repository, clone it to your local device by using the following command:

git clone https://github.com/<your-username>/hanzo-sign

2. Run npm i in the root directory

3. Create your .env from the .env.example. You can use cp .env.example .env to get started with our handpicked defaults.

4. Set the following environment variables:

   • NEXT_PRIVATE_AUTH_SECRET
   • NEXT_PUBLIC_WEBAPP_URL
   • BASE_PATH
   • DATABASE_URL
   • NEXT_PRIVATE_SMTP_FROM_NAME
   • NEXT_PRIVATE_SMTP_FROM_ADDRESS

7. Run npm run dev in the root directory to start

8. Register a new user at http://localhost:3000/signup

---

• Optional: Seed the database using npm run prisma:seed -w @hanzo/esign-prisma to create a test user and document.
• Optional: Create your own signing certificate.
  • To generate your own using these steps and a Linux Terminal or Windows Subsystem for Linux (WSL), see Create your own signing certificate.

Video walkthrough

If you're a visual learner and prefer to watch a video walkthrough of setting up Hanzo eSign locally, check out this video:

Docker

We provide a Docker container for Hanzo eSign, which is published on both DockerHub and GitHub Container Registry.

• DockerHub: https://hub.docker.com/r/hanzo-sign/hanzo-sign
• GitHub Container Registry: https://ghcr.io/hanzo-sign/hanzo-sign

You can pull the Docker image from either of these registries and run it with your preferred container hosting provider.

Please note that you will need to provide environment variables for connecting to the database, mailserver, and so forth.

For detailed instructions on how to configure and run the Docker container, please refer to the Docker README in the docker directory.

Self Hosting

We support a variety of deployment methods, and are actively working on adding more. Stay tuned for updates!

Fetch, configure, and build

First, clone the code from Github:

git clone https://github.com/hanzoai/esign.git

Then, inside the hanzo-sign folder, copy the example env file:

cp .env.example .env

The following environment variables must be set:

• NEXT_PRIVATE_AUTH_SECRET
• NEXT_PUBLIC_WEBAPP_URL
• BASE_PATH
• DATABASE_URL
• NEXT_PRIVATE_SMTP_FROM_NAME
• NEXT_PRIVATE_SMTP_FROM_ADDRESS

If you are using a reverse proxy in front of Hanzo eSign, don't forget to provide the public URL for the NEXT_PUBLIC_WEBAPP_URL variable!

Now you can install the dependencies and build it:

npm i
npm run build
npm run prisma:migrate-deploy

Finally, you can start it with:

cd apps/remix
npm run start

This will start the server on localhost:3000. For now, any reverse proxy can then do the frontend and SSL termination.

If you want to run with another port than 3000, you can start the application with next -p <ANY PORT> from the apps/remix folder.

Run as a service

You can use a systemd service file to run the app. Here is a simple example of the service running on port 3500 (using 3000 by default):

[Unit]
Description=hanzo-sign
After=network.target

[Service]
Environment=PATH=/path/to/your/node/binaries
Type=simple
User=www-data
WorkingDirectory=/var/www/hanzo-sign/apps/remix
ExecStart=/usr/bin/next start -p 3500
TimeoutSec=15
Restart=always

[Install]
WantedBy=multi-user.target

Troubleshooting

I'm not receiving any emails when using the developer quickstart.

When using the developer quickstart, an Inbucket server will be spun up in a docker container that will store all outgoing emails locally for you to view.

The Web UI can be found at http://localhost:9000, while the SMTP port will be on localhost:2500.

Support IPv6

If you are deploying to a cluster that uses only IPv6, You can use a custom command to pass a parameter to the Remix start command

For local docker run

docker run -it hanzo-sign:latest npm run start -- -H ::

For k8s or docker-compose

containers:
  - name: hanzo-sign
    image: hanzo-sign:latest
    imagePullPolicy: IfNotPresent
    command:
      - npm
    args:
      - run
      - start
      - --
      - -H
      - '::'

I can't see environment variables in my package scripts.

Wrap your package script with the with:env script like such:

npm run with:env -- npm run myscript

The same can be done when using npx for one of the bin scripts:

npm run with:env -- npx myscript

This will load environment variables from your .env and .env.local files.
