A standalone universal viewer & verifier for blockcerts credentials
The component is developed with Polymer 3. To use the component in your project, install it via:
npm i @blockcerts/blockcerts-verifier
npm run start
Will make the demo page available on http://localhost:8081/demo/.
The sanitizer is used in order to protect against malicious certificates that could hold XSS attacks.
It is an overlay of the xss library, since at times, you might want to be able to configure or adapt the whitelist to your own needs.
To modify it, you should edit the sanitizer/index.js file.
More specifically if you wish to whitelist some CSS properties, add them to the object whiteListedCssProperties.
npm run build:sanitizer
This will generate the sanitizer.js file, which is then used by the application and the tests.
If you want to work on the sanitizer in watch mode (and auto-generate your changes), use the following command:
npm run build:sanitizer -- -w
npm run test:application
NOTE: application must be started to run the tests, or at the very least the mock-server via the npm run start:mock-server (automatically included in the npm run start command).
watch mode
npm run test:application:watch
npm run test:components
"watch" mode
npm run test:components:persist
Will allow refreshing the test page: http://localhost:8000/components/blockcerts-verifier/generated-index.html?cli_browser_id=0
This project is a fork from the Blockcerts open source project, it was extended to aggregate custom presentation and data processing
