The Cydia Impactor is an extremely useful GUI software available for your iOS device to download IPA files, it deletes jailbreak and helps you download and install unsigned iOS applications on an iOS device that has not been jail broken. Now if you have an iOS IPA file that you want installed into your iOS device then you will be able to do it easily using the Cydia Impactor/Cydia Eraser.

Now recently many iOS users who work with Cydia Impactor started encountering a new error called the http-win.cpp 158 error (fix)by the Cydia Impactor which was quite the issue because it did not allow the IPA files to get installed in their iOS devices. Also, alarmingly, the jailbreak users also have been unable to install the iOS 10 Yalu Jailbreak due to this very error.  If you have encountered the error, the error message is displayed like this:fix http-win.cpp 158

 “http-win.cpp:158 Peer certificate cannot be authenticated with given CA certificates SSL certificate problem: self signed certificate in certificate chain”


This error did not seem to be appearing for the users of Linux and Mac machines, but only the Windows users in general. So one way to solve the problem, is to install your IPA files using either Mac or Linux machines. But if you do not own a Mac or Linux machine, do not worry, Saurik has released a quick fix to this problem:
