I have a request and have a SecretApiKey, how do I sign the request body using System.Security.Cryptography.HMACSHA256() whose key to the requests was SecretApiKey?

According to Telerik docs, localhost should be automatically captured when capturing is enabled in Firefox and FiddlerHook is installed.

Even though this has been working successfully on my desktop for several years, it has stopped working after the latest Firefox update (to v. 93.0 (64-bit) even though FiddlerHook is still present within Firefox. Note that all non-localhost traffic is still captured as expected. Localhost will be captured if the FiddlerFox extension is installed and enabled, but this requires manually toggling a switch control in FiddlerFox while using Fiddler.

Is this functionality now broken, and, if so, can it be fixed?

 

Thank you very much,

I am using Fiddler to capture android app traffic by following this tutorial here: https://www.telerik.com/blogs/how-to-capture-android-traffic-with-fiddler

I've successfully set up everything and I'm able to capture traffic just that I'm also getting traffic from my windows machine where I have fiddler installed and acting as a proxy.

1. How can I config fiddler to only show captured traffic just from my android device?
2. Moreover, if I've installed the certificate and configured the proxy on 2 different android devices how can I differentiate between the two? Right now the only solution is to turn wifi off on one of the devices.
3. Is there a way I can see somewhere in the left traffic list stream window or the right Inspectors window and tabs what's the ip of the device that the traffic data belongs to? For example, my android device 1 has 192.168.0.10 and android device 2 has 192.168.0.20. I would like to see somewhere in the request and/or response this IP for the same reason described above - to be able to differentiate traffic captured from one source from the other.

for a year i was able to see it in english but now when i use Fiddler in the Raw body it shows DCAoUTRTRZPkYOPP^<[YSRTKoTPB UEAS]\mERDX@F h;NE^Y>RYD LW[hD@k ]WADFSVD:QXTJ\SYR@

 

How do i make it show english again? When i use Cheat Engine im able to see what i would usually see, if i tick UTF-16 (before it broke i was able to view it without ticking UTF-16, but not anymore ). Usually it would be perfect english in the JSON but now the JSON doesn't even show anything.

Charles support the function, so can solve SSL-Pinning

Hi,

I've been unable to connect to any website from my browsers suddenly few days ago. But other connection okay (ping/email/ftp/etc). At that point of time, I still do not install Fiddler

So I downloaded, install and start Fiddler to check what happen to the packet when I'm browsing.

To my surprise, when I start Fiddler, I am able to browse again. So, I suspect, my OS is blocking my connection. So, when I start FIddler, the packet is being routed by Fiddler to its tunnel and I can connect to website again

So, basically I have no problem with Fiddler, in fact Fiddler help me conclude that my own laptop block my connection to website.

However, I just need your help to teach me, how to know, at which configuration in Windows, that it block my connection. Can you give me any guideline or hint. (When I refer to WIndows Firewall rule, I am unable to eyeball any obvious rule that block connection to website)

Great thanks in advance for your help!!

What would be the best way to forward socket messages captured with Fiddler using OnWebSocketMessage to my application? I'm thinking of opening a http  listen port in my app and send the captured message using WebClient. Would you recommend a better way?

I'd like to forward socket messages to my app for further analysis.

 

Thank you.
