The user requests a certificate using a JWT token. The token is hashed to mb5 and appended to the filename. If a file is found by this hash, the found file is returned. If not, a new one is generated.

Demo: demo certificate

Installation will be using docker.

//--/ Cloning 
git clone git@github.com:FromSi/certificate-generate.git && cd certificate-generate

//--/ Install dotenv
cp .env.example .env

//--/ Run/Restart
make restart

To get a certificate, you need to make a GET request:

GET //<lang>/<file_format>/<save>/<jwt_token>

• lang - language (en)
• file_format - what type of file to get (png|pdf)
• save - download (true|false)
• jwt_token - certificate data

GET //en/pdf/false/eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJwZXJzb25fbmFtZSI6ItCS0LXQsdC10YAt0J_RhNC70Y_Rg9C80LXRgCDQktC70LDQtNC40YHQu9Cw0LIiLCJvcmdhbml6YXRpb25fbmFtZSI6IkdpdEh1YiIsImNlcnRpZmljYXRlX251bWJlciI6IkdIMDAwMSJ9.oS4mddLm0nPwFQAeZ1D69M4Y-cWhN876DKtoliKnbLY

JWT token can be reconfigured with https://jwt.io and secret-key SECRET.

You can find the file res/en.json in the project. This is the config to generate certificate and merge with JWT.

When we read a file res/en.json. Attention to the name of the key config:

{
  "config": {
    "bg_path": "res/en_bg.png",
    "font": {
      "100": "res/fonts/StyreneAWeb-Thin.ttf",
      "300": "res/fonts/StyreneAWeb-Light.ttf",
      "400": "res/fonts/StyreneAWeb-Regular.ttf",
      "500": "res/fonts/StyreneAWeb-Medium.ttf",
      "700": "res/fonts/StyreneAWeb-Bold.ttf",
      "900": "res/fonts/StyreneAWeb-Black.ttf"
    }
  },
  ...
}

The configuration allows you to define the initial data for the project.

This is a block of text:

{
  ...,
  "organization_name_title": {
    "x": 1,
    "y": 1,
    "text_size": 32,
    "weight": 300,
    "text_color": "#2D309A",
    "text": "Organization",
    "dependence": "organization_name" <- will be generated if organization_name has text(jwt|static)
  },
  ...
}

If there is no text key, the organization_name_title key will be taken from the incoming JWT token.
