<p dir="auto">I'm resolving this. I think it's better as it is now, putting that code outside of <code>stek.c</code> would break separation of concerns, and would pollute the session ticket code and make it harder to understand.</p>
<p dir="auto">I've added a line to the docs of <code>_gnutls_initialize_session_ticket_key_rotation</code> however.</p>
