Under some circumstances you want openssl s_client to be absolutely silent
about what its doing. Unfortunately the -quiet option available does not
suppress the verification messages of the certificate when the connection
is established.

Howto reproduce:
    openssl s_client -connect host.example.com:443 -quiet

Expected behaviour:
    netcat with crypto and no output on stderr

Actual behaviour:
    netcat with crypto and certificate verification messages spammed into stderr

Kind regards,

You do realise that s_client is a debug tool and that by default
it allows any certificate?

I'm not arging this is a bug or not.

I do wonder if you know what you're doing or not.

Hi Kurt,

Yes. Nothing new you are telling. And could we now please stop arguing
of WHY I'm reporting this and switch to take care of the actual bugs? TIA.

Anyway: When I ask a tool to be silent or keep quiet I want this tool to
respect this. Everything else is a bug; that simple.

Example: If you use your hammer to get a nail into the wall you don't
want that hammer to ask for confirmation before hitting your finger when
you specially asked for --just-do-so mode.
Kind regards,
Benny Baumann.
