OSSLR

OSSLR is a script that adds copyright notices to your existing CycloneDX Software Bill-of-Materials (SBOM). It generates a license report in PDF format based on that SBOM.

Features

• OSSLR adds copyright notices to your SBOM
• It currently only supports SBOMs provided in JSON format
• The result can be exported as a PDF or JSON

Set-up with Docker

• Place the Dockerfile into your project root directory
• Inside your shell in your project root directory run these two commands:
  • docker build . -t osslr this will create a docker image.
  • docker run -t -v $(pwd)/out:/home/app/OSSLR/out -e ACCESS_TOKEN="your github access-token" -e DEFAULT_VALUES="path/to/default-values" osslr this will start the container and the OSSLR script. The second environment variable namely the DEFAULT_VALUES is optional.
• After the program terminates, you should see three new files in the out folder in your project root directory:
  • updatedBom.json
  • updatedBom.pdf
  • missingValues.json

Manual Set-up

Download script for generating SBOM (Software Bill-of-Materials) that will contain the compilation of all project dependencies in JSON and XML format.

npm install --location=global @appthreat/cdxgen

Also create an access token on GitHub by going to: Settings >> Developer Settings >> Personal Access Tokens >> Generate New Token. Paste your access token into a .env file in the project folder exactly like this: ACCESS_TOKEN="your-github-acces-token".

Secondly, make sure you set the FETCH_LICENSE environment variable.

For Unix systems:

export FETCH_LICENSE=true

For Windows systems:

set FETCH_LICENSE=true

To generate a BOM file of your project, run this command inside the project folder.

cdxgen -o bom.json

To Run the license checker program:

npm run license_checker -- --bomFile="path/to/your/bom.json"

Or:

npm run license_checker -- -p "path/to/your/bom.json"

Addtionally one can include a second file with default entries, which then will be included in the output file(s):

npm run license_checker -- --bomPath="path/to/your/bom.json" --defaultsPath="path/to/your/default.json"

Or:

npm run license_checker -- -p "path/to/your/bom.json" -d "path/to/your/default.json"

In the json format with this structure:

{
    "components": [
        {
            "group": "MaibornWolff",
            "name": "OSSLR",
            "version": "~1.2.3",
            "licenses": [
                {
                    "license": {
                        "id": "1234",
                        "url": "https://best-license.com"
                    }
                }
            ],
            "copyright": "M-Copyright"
        }
    ]
}

After the program terminates, you should see two new files in the out folder: updatedBom.json and updatedBom.pdf. Furthermore there might be another file missingValues.json ,which is outputted, if the data retrieval failed for certain packages. These packages are then listed in the aforementioned structure.
