# Browser PKCS#10 CSR generation PoC

This repository contains a small proof of concept implementation of browser
based PKCS#10 certificate signing request and PKCS#12 key store generation
using [node-forge](https://github.com/digitalbazaar/forge).

The backend is implemented in [Go](https://golang.org/) and utilizes openssl
for the signing operations.

## Running

1. Clone the repository

    ```
    git clone https://git.dittberner.info/jan/browser_csr_generation.git
    ```

2. Get dependencies and build assets

    ```
    cd browser_csr_generation
    npm install --global gulp-cli
    npm install
    gulp
    ```

2. Setup the example CA and a server certificate and key

    ```
    ./setup_example_ca.sh
    openssl req -new -x509 -days 365 -subj "/CN=localhost" -addext subjectAltName=DNS:localhost -newkey rsa:3072 \
      -nodes -out server.crt.pem -keyout server.key.pem
    ```

3. Run the Go based backend

    ```
    go run main.go
    ```

    Open https://localhost:8000/ in your browser.

4. Run gulp watch

    You can run a [gulp watch](https://gulpjs.com/docs/en/getting-started/watching-files/)
    in a second terminal window to automatically publish changes to the files
    in the `src` directory:

    ```
    gulp watch
    ```
