Nginx is a very good choice for HTTPS.

Here's a first track to follow:

Odoo implements HTTP but cannot do SSL termination on its own. You must terminate it somwehere else which commonly is done with Apache or Nginx and then proxy forward the request to Odoo.

Thank you for this answer.

Is this only my feeling, that is a companycrtitical Webapplication without Transport encrytion a nogo in these days?

In my Company all Infrastructure Components are transport encrypted, without dont receive the ok from our IT-Security and Architects.

It it planed to implement SSL in OpenERP / Odoo in this or next Version?
