Um, there's just one little problem with this; what do you think about the attached public-domain patch that removes what looks very much like a stray quote character?

Windows Certificate Store
by j nasty 07 Aug '14

07 Aug '14

I haven't been able to get a definitive answer and can't find the information I need through traditional searching around. Anyways, is it possible to have sTunnel access the Windows certificate store to get the certificate that will be used for client authentication? If so, how can this be configured in sTunnel's configuration file? Or can you at least point me in the direction I can find the information I'm looking for? Many thanks in advance everyone!

Possible false positive trojan detection on stunnel-5.02-installer.exe
by Drew Mayo 06 Aug '14

06 Aug '14

Hi all, This is just an FYI. I'm a recent user of stunnel, and one of my team has just alerted me that f-prot (and unfortunately hence google drive) detects the current windows installer for stunnel 5.02 as a trojan. virustotal (which confirms it matches the sha256) tells me that the file is detected as: W32/Trojan.TDWH-2255 W32/Trojan3.JUA I've raised a misclassification request with f-prot, but of course that will probably take some time to get resolved. Of course, it is remotely possible it's not false, but i'm betting the other way. -d

More peer cert info export, new verify option
by Michal Vaško 05 Aug '14

05 Aug '14

Hello, for our current use-case we needed to add functionality to stunnel and therefore have made few patches. We distribute these patches with our software and were wondering what do you think about including them directly in stunnel. Firstly, we need peer certificate fingerprints in MD5, SHA1, SHA224, SHA256, SHA384 and SHA512. Patched stunnel exports all these in separate variables "SSL_CLIENT_*". Secondly, we could need subjectAltName values. Patched stunnel exports these in "SSL_CLIENT_SAN", but only rfc822Name, iPAddress and dNSName as we need only these. It could easily be expanded to all the values. Lastly, we required verification as if we first used verify = 2 and after failing trying verify = 4 (verify = 3 is technically verify = 2 AND verify = 4, if I am not wrong, and we need verify = 2 OR verify = 4). For this purpose my patch adds new verify = 5 option. I want to say that we did not just make all these requirements up, but we want to conform to RFCs describing NETCONF over TLS and its configuration. All the patches are included so you can go through them. Thank you. Kind regards, Michal Vasko

I have already requested the CD of software from OpenSSL -- that section does not really assist with the build functions.

OpenVPN over stunnel
by Derek Cole 24 Jul '14

24 Jul '14

Hello, I am doing something similar to what is happening in this scenario: http://kyl191.net/2012/12/tunneling-openvpn-through-stunnel/ That is, I have set my openvpn client configuration to be "remote localhost port" where port is the port my stunnel client is listening on the same box as my openvpn client. This seems to work - I get connected to OpenVPN server fine, however, I don't seem to be able to ping the openvpn server by either of it's public or private ip addresses. In fact, it seems like when I do a tcpdump on the stunnel server, I don't see any incoming traffic on port 443. How is it possible that I am getting the VPN connection, but then the rest of the traffic just sort of stops going through stunnel? My stunnel client service looks like the following: [openvpn] accept = 127.0.0.1:5150 connect = stunnelserver:443 and my stunnel server looks like: [ovpnout] cert = mycert.pem accept = 443 connect = openvpn server Any ideas?

FIPS compliant Stunnel build
by Michael Curran 23 Jul '14

23 Jul '14

Hello -- Is Stunnel (any version) compatible with Fips-2.0 for compliance? I have found one individuals instructions for compiling fips-2.0.5 , but he calls out a prefix= in his configure for FIPS which breaks 140-2 compliance rules and makes the build no longer viable >From the Fips-2.0 userguide "Note that as a condition of the FIPS 140-2 validation no other user specified configuration optionsmay be specified. This restriction means that an optional install prefix cannot be specified –however, there is no restriction on subsequent manual relocation of the generated files to thedesired final location." I know that Stunnel compiles just fine with OpenSSL1.0.1 versions, but there appears to have been a difference in the method of validation and installation of FIPS modules into a seperate modular directory, and is not located in the openssl/include files after build now The stunnel configure script only looks for fips-1.0 as well , so my base assumption is might not be capable of handling FIPS-2.0 at this time.
