This project attempts to implement a JavaScript polyfill for the <keygen> tag, which is being removed from modern browsers.
openssl.js is used for the heavy lifting.
<!doctype html>
<meta charset="UTF-8">
<script src="keygen.js"></script>
<script type="module">
import { OpenSSL } from './openssl.js/dist/browser.openssl.js';
keygenJS(OpenSSL);
</script>
<style>
.keygen-algorithm { /* algorithm dropdown (select) */ }
.keygen-pkeyopts { /* additional key options (text input) */ }
.keygen-status { /* status/progress (span) */ }
.keygen-link { /* generated certificate download link (a) */ }
</style>
<!-- keygen.js assumes the form target returns a certificate: -->
<form action="/spkac-endpoint.php" method="post">
<keygen name="key">
<!-- More optional attributes:
- keytype (rsa / rsa-pss / x25519 / x448 / ed25519 / ed448)
- challenge
- -keygenjs-pkeyopts (e.g. "rsa_keygen_bits:4096")
and standard HTML attributes:
- autofocus
- disabled
- form

<input type="submit">
