This is a proof of concept project that implements Signed Exchanges (SXG) built on Sig Network. This project is still work in progress

1. Run one of mock signer or sig signer:

   • For mock signer: node mock-signer.js
   • For sig signer: node sig-signer.js

2. Generate CSR:

   python generate-csr.py
   

   This generates a CSR without signature, sends it to the signer to sign and pack the signed CSR, then dumps it in PEM format.

3. Register a DigiCert account and upload the CSR to obtain a SXG-supported certificate.

4. Host the certificate and public key on a server:

   • Ensure your server is configured to serve these files securely.

5. Generate SXG for each static file on your site:

   python generate-sxg.py
   

   (TODO)

6. Host SXG files alongside your site:

   • Configure your web server to serve both the original files and their SXG counterparts.

To set up the environment for this project, follow these steps:

1. Clone the repository and its submodules:

   git clone --recursive https://github.com/your-repo/SIG-SXG.git
   cd SIG-SXG
   

2. Install Conda If you don't have Conda installed, download and install it from the official Conda website.

3. Create a new Conda environment named 'nearsxg':

   conda env create -f environment.yml
   conda activate nearsxg
   

4. Install project dependencies:

   npm install
   

5. Build the cryptography module:

   cd cryptography
   

6. Install Rust: If you don't have Rust installed, you can install it using rustup. Visit https://rustup.rs/ for installation instructions or run:

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
   

7. Install build requirements:

   pip install -r .github/requirements/build-requirements.txt
   

8. Build the cryptography module using maturin:

   maturin build
   # There will be an output python package, install it with pip install path/to/package
   

9. Return to the project root directory:

   cd ..
   

10. Build the webpackage:

    cd webpackage
    go build -o ../gen-signedexchange go/signedexchange/cmd/gen-signedexchange/main.go
    cd ..
