Usage

import * as libsni from "@litert/tls-sni";
import * as TLS from "tls";
import * as FS from "fs";

// 1. Create a certificate mananger object.
const cm = libsni.certs.createManager();

// 2. Load a certificate into certificate mananger
cm.use(
    "default",
    FS.readFileSync(`./certs/default/cert-20190801.pem`),
    FS.readFileSync(`./certs/default/key-20190801.pem`)
);

// 3. Create a TLS server with the SNI callback provided by ceritificate manager.
const server = TLS.createServer({
    SNICallback: cm.getSNICallback(),
    ...otherOptions
});

// ...

// 4. Check if there are some certificates outdating.

const outdatingCerts = cm.findExpiringCertificates(
    Date.now() + 28 * 86400000 // Optional, 7 days by default
); // Get the list of certificate names, which are outdating in 28 days.

// ...

// 5. When a cert is being outdated, replace it with a new one.
cm.use(
    "default",
    FS.readFileSync(`./certs/default/cert-20190901.pem`),
    FS.readFileSync(`./certs/default/key-20190901.pem`)
);
