TLS 1.X to 2.X

[Michael]

I am told that we could send transactions to fiddler in TLS 1.x and fiddler then would forward transactions in TLS 2.0 to payflowpro.paypal.com.  payflowpro.paypal.com would then return TLS transactions to fiddler and fiddler then would return the transaction to our Ecommerce platform.

Where do I start with this?

Thanks,

Mike

Hello,

With Fiddler that should work right out of the box. Just make sure that you go to Tools-> Options -> HTTPS and add tls1.2 to the Protocols list.

I have done this

So, how do I intercept my TLS 1.2 and forward as 2.X?

Thanks in advance,

Mike

Well when you run Fiddler on the system where your app runs do you see the traffic from your app in Fiddler? If not then you will have to set Fiddler to be the proxy of your app (127.0.0.1:8888). On start Fiddler sets itself as the WinINET proxy but your app might not respect these settings or use a different network API so the proxy setting is really app dependent.

On a side note there is no TLS 2.X. The latest version is 1.2. Hopefully you got the version number wrong but it might be the case that you are trying to do something completely different so please double check the stuff on your side.

I do see my app.  Now how do I filter my app traffic and forward?

[Tsviatko Yovtchev]

Filtering is done in the filters tab but I cannot really understand how filtering is related to your scenario. Would you elaborate some more?

 Also what would you like to forward and where to?

I am capturing outbound traffic but it seems when transactions are being verified (returned) from paypal, they are not able to pass through fiddler.

Please advise.

What do you mean by they are not able to pass through Fiddler? You see them in Fiddler but you don't see them in browser? What error does the browser give? Is it the browser actually or is it an app of your own?
