Javascript CT implementation

CTUtils is a CT implementation for Javascript. It currently supports the protocol as defined in RFC6962.

There are classes for all structures defined in the specification with methods for verification, binary parsing and dumping where appropriate.

There are also two different helper classes that perform common operations on CT log lists and certificates.

Installation

Use:

npm run build

to build the module.

Use:

npm run generate-docs

to generate the documentation

Requirements

If running under node, you will need a fetch and a webcrypto polyfill, such as node-fetch and node-webcrypto-ossl. After importing them, you need to set both engines using setFetch and setWebCrypto. As an example, you can use the following:

const fetch = require('node-fetch');
const WebCrypto = require('node-webcrypto-ossl');
const CTUtils = require('ctutils');

const webcrypto = new WebCrypto();

CTUtils.setFetch(fetch);
CTUtils.setWebCrypto(webcrypto);

Usage

Please see the generated documentation for sample usage.

You can also check the examples in the examples/ folder.
