When using Fiddler to capture packets, we sometimes need to capture https packets. This requires configuring https monitoring.

First find Tools --> Options

 

In the pop-up menu, select https and select capture https.

 

 

After the OK configuration is complete, a window pops up prompting you to install the certificate. Click Install and restart Fiddler.

However, sometimes there is no pop-up window to install the certificate or there is no prompt at all. This usually occurs in Win7, and there is a bug in. net Framework4.0 In the https aspect of Win7.

The solution is

1. Run the cmd command to find the installation directory of fiddler, for example:

Cd C: \ Users \ JayshSoft \ AppData \ Local \ Programs \ Fiddler

Run the following command:

Makecert.exe-r-ss my-n "CN = DO_NOT_TRUST_FiddlerRoot, O = DO_NOT_TRUST, OU = Created by http://www.fiddler2.com "-sky signature-eku 1.3.6.1.5.7.3.1-h 1-cy authority-a sha1-m 120-B 09/11/2018

 

Note: the last date of this command must be later than the current date. Otherwise, the certificate creation will expire.

 

In this way, you can correctly install the certificate after re-configuration.
