This makes it harder for malicious parties to intercept private data from apps and services.

Changes to NougatĪndroid 7 ('Nougat') improves performance and battery life in several ways. This is because Android stores the certificates in the credential storage, which is encrypted using a key derived from the lock screen code.Īndroid 7 made things even worse though. Installing a certificate makes the Android OS display a warning about the network being monitored every 15 minutes, and requires the user to set a password on their lock screen. An exception to this is Android, which has two stored: one for system certificates (which come with Android itself) and user authorities (which the user has installed themselves).Īndroid is rather paranoid about SSL certificates, so installing a certificate the official way is made as user-unfriendly as possible. Making a device trust a certificate authority is relatively simple: just import the root authority certificate and the device will store the certificate in the centralized certificate store. It also allows me to sign my binaries so I can run my custom Powershell scripts without lowering the security settings. This is useful for debugging/reverse engineering apps and websites made by others, but it's also very useful for securing intranet websites without requiring a certificate from an external certificate authority such as Let's Encrypt. So I run my own root certificate authority. If you don't want any background and just want to know how to install your own certificate authority on Android 7, click here to skip the background info!
