How to use openssl with busybox's httpd?

Question

I have a busybox embedded device that provides http services with its built-in httpd. I want to provide https to improve its security, therefore I want to use openssl (or a similar software) with busybox httpd. On the internet there are a lot of tutorial for apache, tomcat and so on, but I'm not using these. What should I do?

Answer 1

Busybox httpd does not support SSL; however, Stunnel can be used with it to provide SSL encryption. Stunnel acts as a "wrapper" which can be used to provide SSL encryption for services which do not support it natively.

An example: 4MLInux Server (a linux distro) uses httpd from Busybox, and Stunnel is used for the "https" protocol. More info can be found at freecode. An online demo is available here: http://server.4mlinux.com. (this example is from an editor via the stackexchange edit suggestion system)
