+This is a demo/test page for generating FIDO keys and signatures in SSH
+formats. The page initially displays a form to generate a FIDO key and
+convert it to a SSH public key.
+</p>
+<p>
+Once a key has been generated, an additional form will be displayed to
+allow signing of data using the just-generated key. The data may be signed
+as either a raw SSH signature or wrapped in a sshsig message (the latter is
+easier to test using command-line tools.
+</p>

+Lots of debugging is printed along the way.
