[stunnel-users] https to https proxy

I'll bite - probably missing something.  Why not have your application
output clear text to stunnel and set stunnel to TLSv1.2?  In other words,
drop the SSL from your application.

If that won't work I think you can do it with two stunnels (I got it to work
once before I did the above).  One accepts SSLv3 and outputs clear text . it
is the client=no option.  The output goes to a stunnel that is client=yes
and is set to TLSv1.2 . which outputs to your final destination.

The output from the client=no would be to localhost on some port that fires
the second stunnel.

I suspect you have to use different port numbers.

All guesses as I am not sure exactly what you are doing . but if it helps,
great :)

Hi,

Our punchout vendor switched their site to only accept tls 1.2 over the
weekend. Unfortunately our application will only support SSL. 

We are using stunnel with other vendors but can control the inbound host
name. This recent one is one we can't manage as it is the software provider.

I found a solution for doing https to https. I'm unclear how I get the first
https traffic to route to stunnel as the initial call will be from the
application will be to the external host..

Any thoughts on whether this would work for my situation?  Appreciate any
thoughts..

[Tunnel_in]
client = yes
accept = host_ip:443
connect = localhost:54321

[Tunnel_out]
client = no
accept = localhost:54321
connect = externalhostname:443

Best regards,

Dan
