Does Stunnel support a connection without encryption?

1 question about Stunnel. I would like to use Stunnel as a FIX (Financial Information eXchange) Internet gateway to support both SSL and non-SSL connections. Can Stunnel do without encryption? I just tried with a simple socket, but he watched Stunnel reject the connection, saying β€œwrong protocol” or something like that.

It is possible to use SSL / TLS without encryption using cipher suites with zero encryption (for example, TLS_RSA_WITH_NULL_SHA ), which are disabled by default, but can be set using the ciphers option for Stunnel. However, you will still use SSL / TLS, which you do not seem to be looking for.

It looks like you're basically looking for what is commonly called TCP bouncer. You have to find many implementations.
