I cannot try anything before entering my CC number (and paying, no free month or anything), nor finding any detailed information about the setup (apart from &#x27;public&#x2F;private key client side JS&#x27;). But the site&#x2F;server&#x2F;data center security probably <i>does</i> matter if the JS is hosted at their site &#x2F; servers.<p>Edit:
See link below: <a href="https:&#x2F;&#x2F;privateforms.net&#x2F;embed&#x2F;rNKlzL" rel="nofollow">https:&#x2F;&#x2F;privateforms.net&#x2F;embed&#x2F;rNKlzL</a><p>So you get jquery, moment, bootstrap + datatimepicker, kbpgp and a few lines of glue to use kbpgp to send and XMLHttpRequest, basically:<p><pre><code>    kbpgp.KeyManager.import_from_armored_pgp({
        armored: &#x27;-----BEGIN PGP PUBLIC KEY BLOCK-----\n&#x27; +
                 &#x2F;* key *&#x2F;
                 &#x27;-----END PGP PUBLIC KEY BLOCK-----&#x27;},
        function(err, keyManager) {
            kbpgp.box({msg: &#x27;**form=data**&#x27;, encrypt_for: keyManager},
            function(err, encryptedString, encryptedBuffer) {
                &#x2F;&#x2F;send result;
            }
        );
    });</code></pre>
