How to configure STunnel to use cert. from certificate store
by Chicoine, Jonathan 12 Dec '18

12 Dec '18

How in the word you specify the certificate to use from the windows certificate store (for example, on Windows 10 or Windows Server 2012)? The documentation obviously says to use the "cert" config option to specify a file (and the "key" config option for the private key) ... but to use a cert from the windows certificate store, shouldn't it be the certs "common name" field or thumbprint ... or something. Am new to this whole thing and have been googling for the answer for days. Any help would be greatly appreciated. -jonathan

stunnel 5.50 on Solaris 10
by Udo Erdelhoff 12 Dec '18

12 Dec '18

Hi, quick heads-up to anybody building/using stunnel 5.50 on Solaris 10 and wondering where the "Invalid configuration file name" errors are coming from: The problem is the call to realpath in line 334 of options.c, it uses NULL as second argument as a request to have the realpath function allocate the memory buffer for the sanitized string. This variant of realpath is not supported on Solaris 10, and leads to EINVAL (error code 22). Quickest fix is to run configure and then manually change src/config.h to have /* #undef HAVE_REALPATH */ instead of #define HAVE_REALPATH 1 -- "Treason is a charge invented by winners as an excuse for hanging the losers." - Benjamin Franklin, ca. 1776

Support for multiple root CAs
by Tom Bentley 07 Dec '18

07 Dec '18

Hi, I'm using stunnel to secure communication between nodes in a cluster, using a self-signed CA to sign the server certs and the `verify = 2` config parameter. This works great. What I want to be able to do is replace the CA key and certificate without breaking the cluster. How I thought this should work would be: 1. Configure the stunnels to trust both the old and new CA certificates while the nodes continued to use server certificates signed by the old CA key. 2. Switch to using using server certifcates signed by the new CA key. 3. Finally remove trust in the old CA certificate. I'd tried this by putting both CA certificates in a single file and using `CAfile` config parameter, and also by using the `CApath` config parameter with both root CA certificates in the configured directory, but I've not been able to get this to work while keeping `verify = 2`. It does work if I temporary use `verify = 0`, but obviously that means I've not got TLS authentication duration the duration of the process. Can anyone confirm whether stunnel supports this use case, and if so suggest where I might be going wrong? Many thanks, Tom

Hi Janos, mail (SMTP / POP / IMAP) are other protocols as HTTPS. I was not able to connect via sTunnel to a server via HTTPS - and this was the reason to create and use my HTTPSProxy. HTTPSProxy is based on this code (local front- and rear proxy are connected directly without Proxomitron): https://prxbx.com/forums/showthread.php?tid=2172 https://prxbx.com/forums/showthread.php?tid=2191&pid=19252#pid19252 You can build your own release with python if you do not trust the versions offered by me or HeinoGanda on MSFN.

Hi Janos, you can use a local proxy to "translate" HTTPS TLS1.0 to TLS1.2 Look here: https://msfn.org/board/topic/176344-problems-accessing-certain-sites-https-… HTTPSProxy (and tools) manage the whole traffic locally (in- and outgoing HTTPS), but needs manually configuration as described in the help files.

If by "forward to the current site address dynamically" you meant "forward to the current address of one specific domain" then stunnel can achieve that by adding "delay = yes". However, if I understood correctly, you wanted to let stunnel strip or remove SSL for whatever sites you visit. Then no, I don't think you can achieve that with privoxy and stunnel. If that's what you want, I would suggest you use nginx to remove SSL. The following example configuration will let nginx "upgrade" your HTTP request to HTTPS. events {} http { server { resolver 9.9.9.9; listen 80; location / { proxy_pass https://$host$request_uri; proxy_set_header Host $http_host; } }} You can then point any domain to the nginx server (for example, via the hosts file) and visit the site via HTTP. This will make HTTPS-oly servers happy. That won't strip third-party HTTPS:// URL resources like NewIPNow does, but you can use the nginx "sub_filter" to replace HTTPS with HTTP in HTML. Also there are "security features" like "Content-Security-Policy" that prevent modern browsers from visiting your SSL-stripped sites, but I believe your out-dated browser will happily ignore those. --Zizhong ------------------------------ Message: 3 Date: Tue, 4 Dec 2018 21:37:53 +0100 From: kovacs janos <kovacsjanosfasz(a)gmail.com> To: Zizhong Zhang <zizazit(a)protonmail.com> Cc: "stunnel-users(a)stunnel.org" <stunnel-users(a)stunnel.org> Subject: Re: [stunnel-users] older browsers, stunnel and privoxy Message-ID: <CAOchpkq7vG8vHBCrbVn6d4Eh7M2rd6jEob_huhoG=ZefJnpHLw(a)mail.gmail.com> Content-Type: text/plain; charset="UTF-8" well, what i meant is forwarding to the current address the browser connects to, so basically browsing through stunnel. is it really that complicated to achieve that? if i configure stunnel as a client, and make the browser send traffic to the accept address, shouldnt stunnel encrypt the traffic with TLS and send forward to the connect address? if thats true, shouldnt it also decrypt returning traffic and send back to the browser? when i configured stunnel as both client and server on the same computer, it worked, but the browser still gave 'ssl_error_no_cypher_overlap' errors. probably because the server side decrypted it again before it reached the website's server? i dont necessarily need it to strip encryption, just use anything below TLS 1.1. for example on 'https://via.hypothes.is/' i can visit sites that would otherwise give cypher error, and they stay as https On 12/4/18, Zizhong Zhang <zizazit(a)protonmail.com> wrote: > Hello, > >> im trying to make older browsers be able to display TLS 1.1 and TLS 1.2 >> sites. >> i heard stunnel cant be configured to always forward to the current >> site address dynamically, thats why i would use privoxy. > > If by "forward to the current site address dynamically" you meant "forward > to the current address of one specific domain" then stunnel can achieve that > by adding "delay = yes". > > However, if I understood correctly, you wanted to let stunnel strip > or remove SSL for whatever sites you visit.

Hello, I would like to use stunnel for mail reading from www.hotmail.com . But there are plenty of redirections, to outlook.live.com, login.live.com, outlook.office365.com etc., moreover IP adresses of these servers are changing... Is there any configuration which allowed to use such web server over stunnel? Regards, Olda

stunnel 5.50 released
by Michal Trojnara 04 Dec '18

04 Dec '18

Dear Users, I have released version 5.50 of stunnel. Version 5.50, 2018.12.02, urgency: MEDIUM * New features - 32-bit Windows builds replaced with 64-bit builds. - OpenSSL DLLs updated to version 1.1.1. - Check whether "output" is not a relative file name. - Major code cleanup in the configuration file parser. - Added sslVersion, sslVersionMin and sslVersionMax for OpenSSL 1.1.0 and later. * Bugfixes - Fixed PSK session resumption with TLS 1.3. - Fixed a memory leak in WIN32 logging subsystem. - Allow for zero value (ignored) TLS options. - Partially refactored configuration file parsing and logging subsystems for clearer code and minor bugfixes. * Caveats - We removed FIPS support from our standard builds. FIPS will still be available with bespoke builds.
