Security is important, as right now, devices can be hacked, phished, or scammed in multiple ways. That’s why protections are so important, especially in public areas. Security certificates were invented and widely used to prevent thieves from stealing our data.
By installing a custom security certificate to bypass the “Your network could be monitored” message when connecting to certain networks in KitKat. This pop up can be annoying, and it forces you to ignore the message when it could actually matter.
The certificate can be pushed to /system/etc/security/cacerts/ folder, and the device will interpret it as a trusted certificate. As a result, that little annoyance will be disabled for good for specific sites of your choosing. The certificate file must be saved in PEM format and edited as suggested in the guide. The device must be rooted to allow copying the file to /system partition. After this process is done, the newly created certificate can be freely enabled or disabled from the trusted certificates list.
Note:This is a guide written for Nexus 5 devices. If the file /system/etc/security/cacerts.bks exists on your device, refer to this tutorial.
INSTRUCTIONS
- Save your certificate in the PEM format
- Get the subject of the certificate with "openssl x509 -inform PEM -subject_hash -in CERTIFICATE.FILE" It should be in a format similar to eg "0b112a89"
- Save the certificate into a text file with "openssl x509 -inform PEM -text -in CERTIFICATE.FILE > yourcert.txt"
- Switch the PEM section and the text, "-----BEGIN CERTIFICATE-----[...]" has to be at the beginning of the file
- Rename the file to 0b112a89.0 (replace with the subject you got in step 2)
- Copy the file into /system/etc/security/cacerts/ and make sure chmod permissions are set to 0644 (rw,r,r)
- Your certificate should now show up in the trusted certificate list
Congratzzzz!!!!!Now such popups wont annoy you much
