var app = express();

app.use(rfc7469({
  includeSubdomains: true,
  maxAge: Date.now() + 604800000,
  reportURI: "http://mydomain.com/report",
  pins: [
    "E9CZ9INDbd+2eRQozYqqbQ2yXLVKB9+xcprMF+44U1g=",
    "LPJNul+wow4m6DsqxbninhsWHlwfp0JecwQzYpOLmCQ="

}));

... etc

Usage

rfc7469(options)

Returns a function which can be used as middleware for express.

Options

Name	Type	Required	Example	Default	Description
maxAge	number	✓	123456	N/A	Maximum time the browser will cache this header.
pins	array of strings			[ "one", "two" ]	SHA256 fingerprint of certificate subject
includeSubdomains	boolean		true	N/A	Should the browser use this header for subdomains too.
reportURI	string		"http://mywebsite.com/report"	N/A	URL the browser will send reports to.

reportOnly()

Makes the middleware only set the Public-Key-Pins-Report-Only header instead of enforcing it.

Considerations

It is up to the user that this middleware is only set on connections that are served over HTTPS.
