anyways, here is an article about what i need: https://en.wikipedia.org/wiki/TLS_termination_proxy
except it shouldnt pass the unencrypted data to a server but a browser. on the same page, stunnel is listed under "Servers capable of acting as a TLS/SSL termination proxy". i would be grateful if i could finally make this work

how can i disable verification though? at first i just want to see it work at all. in the howto page, it says this: " Stunnel has 3 methods for checking certificates, which are controlled by the verify option:
* Do not Verify Certificates If no verify argument is given, then stunnel will ignore anycertificates offered and will allow all connections. "
there is no "verify" in the stunnel.conf file, and only the gmail service examples have verifyChain

How would connection between stunnel and server through proxy work? To verify servers identity, stunnel needs to receive and verify servers certificate and since servers address is defined in config file, anything that modifies traffic between stunnel and server will be seen as mitm and that will break connectivity. It might be possible to disable certificate verification, but in that case sslstrip would be better solution. (it would have the same security).

i mean a proxy that can work with the address of the actual website opened in the browser, not just specific addresses defined in the config file.
at least i thought thats what you meant with this: "In case of client (browser), for each remote (https) server to be connected to, stunnnel config file will need an entry; in browser it will not be possible to use DNS names (all servers will have to be addressed as 127.0.0.1:someport where "someport", is port assigned in stunnel conf server entry accept statement), so most links in webpages will not work."
if stunnel can only work with specified addresses, cant a proxy like privoxy be set up at both ends, and stunnel only has to accept and connect to the address of the proxies?

What do you mean by dynamic address proxy?

if stunnel can only accept from and forward to one address, cant that be went around by setting a dynamic address proxy on both sides of stunnel? like: proxy - stunnel - proxy
although i havent been able to connect to even a single website, but
i
didnt try with specifically the IP

There is
only one server, which gets connected by stunnel.
In case of client (browser), for each remote (https) server to be
connected
to, stunnnel config file will need an entry; in browser it will not be possible to use DNS names (all servers
will
have
to be addressed as 127.0.0.1:someport where "someport", is port assigned in stunnel conf server entry
accept
statement), so most links in webpages will not work. It may be feasible for small number of servers, which does not
links
any
external resources.
