The PCAP Remote MITM certificate expired. I tried to de-install and re-install the app, but the installed certificate is always the same with expiry date 19 Aug 2020. I thought when I re-install the app it would automatically generate a new certificate.
I use PCAP Remote on a Samsung tablet with Lineage OS 14.1 (Android 7.1.2) and ADB root enabled. Then I connect to a ADB root shell and copy the certificate from the user certificate store to the system certificate store to allow the it be used for MITM. Please help me generating and installing a new certificate.
