Does anyone have some example code showing usage of public_key:sign and public_key:verify()?  <br>
<br>
I'm having a very difficult time getting the following to work:

I'm generating "escript: exception error: function_clause".<br></div></blockquote><div><br>No first hand experience but since I'd like to do something like this shortly, looked around and found this thread:<br>
