TinyTLSProxy on XP - how to proxy from TLS10 to TLS12

Question

Hi!
I am trying to get the command line switches correct to proxy an application that only uses TLS10 to a newer server using TLS12 (or TLS13).
I only see the -toTLS option and when I use that it do not get through.

Does TinyTLSProxy on XP support TLS10 to TLS12 conversion?

Answer 1

TLS to TLS is conversion is not available in the current public version. Please download the preview version from https://www.rebex.net/getfile/abd251b519484dae93ec48428c05fe6a/RebexTinyTlsProxy-Binaries-v1.6.2.zip

The command line to configure TLS to TLS conversion looks like this:

RebexTinyTlsProxy.exe -TLStoTLS -TLS10:TLS12- 443:httpbin.org:443 -c cert.pfx#password

Please note that you would need to possibly specify -SNI option as well:

-SNI name       Server name for outbound TLS tunnel (SNI extension).

Please also note that for TLS to TLS conversion you need to use a valid certificate for the proxy.

Hi Lukas, a follow on question.
Do you have an estimated release date for this new unreleased version?
Specifically, when would we be able to see the source code up on GitHub?
