Package Exports
- oauth-simple-signature-check
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (oauth-simple-signature-check) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
oauth-simple-signature-check
This package is a simple way to quickly test an OAuth 1.0a signature for validity. As it is intended to be extremely simple, there are no configuration options; however, you may use it as a base if you need different behavior. The algorithm for validating OAuth signatures was adapted from this site: http://lti.tools/oauth/
It was originally designed to simplify OAuth signature validation within the LTI (Learning Tools Interopability) spec, but it can be adapted to many other uses as well.
Assumptions
The package works out-of-the-box with Express.js.
The algorithm assumes you are using HMAC-SHA1 within the OAuth 1.0a spec. Again, you can fork this package and easily change this, if needed. It also assumes you are using UTF-8 for encoding (which you should be).
How to use
Call it in your express.js app, within a route. Here is an example:
const validateOAuthSignature = require("oauth-simple-signature-check");
app.post("/", function (req, res) => {
const isOAuthSignatureValid = validateOAuthSignature(req, process.env.CONSUMER_SECRET);
if (isOAuthSignatureValid)
res.json({ data: {str: "my secret string"} });
else
res.json({});
});
