[stunnel-users] Target version/timeframe for drawing identity certs from Windows cert store?

Wed Sep 22 19:32:30 CEST 2010

Hi David,

Yes, OpenSSL has recently added a functionality called "capi engine" that should allow to use Windows Certificate Store in stunnel. Unfortunately it currently only seems to work with OpenSSL compiled with MSVC and not gcc.

My options are:
1. Wait for OpenSSL to fix this issue or for someone to find a workaround.  I tried to get it working and I failed.
2. Switch to OpenSSL compiled with MSVC. That's inconvenient, but since your company makes money on stunnel it could probably use some of them to convince me to implement such a change.

I agree selection of certificate should be implemented as service-level option. As you probably know each service-level option can also be specified in global section as a default for all service sections.

Starting stunnel from login script is not a problem.

Best regards,
  Mike

Thinking out loud -- probably also, in the case where multiple client tunnels are being set up, a way to make it either a global selection (for all client services), or a service specific selection -- hmm, though global only is probably fine, thinking about, since an integrator could always create a 2nd config, if a 2nd tunnel is needed

I don't know Windows well enough to know if that constrains you (if the window mgr is up during login script exec, etc.).
