U2F Demo Deployment

There are two deployments possible:

NoExt -- The appspot server will call into the expension already bundled into Chrome. This deploys to https://noext-dot-u2fdemo.appspot.com (which is the same as https://u2fdemo.appspot.com).
CrxJs -- The appspot server will call into the unbundled extension that you have. This deploys to https://crxjs-dot-u2fdemo.appspot.com

NoExt

In order to configure the appspot server to the extension that is built into Chrome, set the extension id in u2f-api.js to pfboblefjcgdjicmnffhdgionmgcdmne:

  u2f.EXTENSION_ID = 'pfboblefjcgdjicmnffhdgionmgcdmne';

In order to deploy to https://noext-dot-u2fdemo.appspot.com, set the version value to noext in appengine-web.xml:

  <version>noext</version>

CrxJs

In order to configure the appspot server to call the U2F extension you have, set the extension id in u2f-api.js to kmendfapggjehodndflmmgagdbamhnfd:

  u2f.EXTENSION_ID = 'kmendfapggjehodndflmmgagdbamhnfd';

In order to deploy to https://crxjs-dot-u2fdemo.appspot.com, set the version value to crxjs in appengine-web.xml:

  <version>crxjs</version>
