Questions tagged [android-keystore]

The Android system requires that all installed applications be digitally signed with a certificate whose private key is held by the application's developer. "Android keystore" may also refer to Android Keystore System, introduced in API level 18, which allows storing cryptographic keys securely within an app.

Android requires that all apps be digitally signed with a certificate before they can be installed. Android uses this certificate to identify the author of an app, and the certificate does not need to be signed by a certificate authority. Android apps often use self-signed certificates. The app developer holds the certificate's private key.

"Android keystore" may also refer to Android Keystore System, introduced in API level 18, which allows storing cryptographic keys securely within an app.
