i have installed Bouncy Castle, but cannot change the generator as Bouncy Castle

 

OMG! No offense. but the font-size is so small and blurry that it makes this app worthless.  Too bad I gotta ditch this app.

During the installation of the app I get this screen saying Unhandled Exception:System.IO.FileNotFoundException:Could not load the file or assembly system.core. I also got another error saying "Please add Fiddler classic installion directory to path environment variable". I have included the image. But the app is installed and after that when I try to launch it is not running.  Nothing happens when I run the app.

I am using windows 11 and have Dot net framework 3.5 and and 4.8 installed. Their features are turned on. I tried moving the system.core file from dot net framework to where fiddler is installed, it didn't work.

I have a pcap file and an sslkeylogfile.txt i was able to open the pcap file and add the decryption keys from the log file to wireshark.

But in Fiddler im only able to import the pcap file but can not import the sslkey file

V4.1.2 don't run my macos，I need old version，please help me.

Hey Nick,

Love the software. Could really help us in an upcoming project. One question. I've been playing with the HTTPS decryption. I've installed BouncyCastle and I'd like to run that. When the Root CA is generated, as you will know, DO_NOT_TRUST is displayed as the CAs name. This would be no good in the instance we needed to deploy Fiddler at the clients' site under our guidance. I've found some settings (prefs) namely; fiddler.CertMaker.Root.ExtraParams and fiddler.CertMaker.EE.ExtraParams. I've spent hours before reaching out. I found a bug using one of the other encryption systems, where the Root pref was read into the EE variable in the system, and also vice versa, the EE pref showed up as the Root setting. I've tried passing the -n argument along with the formatted distinguished name. I've had no success, hence why I am reaching out to you. Can you please explain to me how to change the Root CA Common names for the PoC setup Im building for an upcoming project?

Love the software and documentation. It's really great.

Warm regards

Hello. I want to scan the traffic in an application on iOS, but the traffic is not scanned. I've done all the debugging with the certificates. Traffic is scanned in other applications, but this app (name: arc8 application) is not visible. Is there a solution to open this http://api.prod.arc8.io:443 traffic?

Hello, I want to implement a functionality with AutoResponder in fiddler classic, where only specific url requests are allowed to pass, and all other requests are blocked.

My solution is adding a rule: specificURL.com, and leave the Action and the "Unmatched requests passthrough" option empty.

But the result is, the specificURL.com request return the "404 Fiddled" status code ( and other requests are blocked as expect).

If I choose any of an Action, such as "200_SimpleHTML.dat" or any local file,  the request won't return 404. But I dont't want to choose any of the Actions. I just want the specificURL.com to be requested normally.

Is there a way to disable Live Traffic being enabled in Fiddler Everywhere on startup? I went through the settings and I am not seeing any option.

Looking to understand whether values that fall in the Inspectors -> Webforms tab can be updated without manually “Unlocking for Editing” each session
