Supported devices running Android 9 (API level 28) or higher installed can The feature is enabled for a key, obtain a KeyInfo for the key Modes, padding schemes, and digests with which the key is authorized to be used. Only if the device's secure hardware supports the particular combination of key algorithm, block Keystore keys on the Android device, but not extract them from the device. If the Android OS is compromised or anĪttacker can read the device's internal storage, the attacker may be able to use any app's Android

Material is never exposed outside of secure hardware. When this feature is enabled for a key, its key Secure Element (SE)) of the Android device.

Key material may be bound to the secure hardware (e.g., Trusted Execution Environment (TEE),.

If the app's process is compromised, the attacker may be able to use the app's keys but cannotĮxtract their key material (for example, to be used outside of the Android device). Operations using an Android Keystore key, behind the scenes plaintext, ciphertext, and messages toīe signed or verified are fed to a system process which carries out the cryptographic operations. When an application performs cryptographic

Key material never enters the application process.

Key material of Android Keystore keys is protected from extraction using two security measures: Specify authorized uses of their keys and then enforcing these restrictions outside of the apps' Secondly,Īndroid KeyStore mitigates unauthorized use of key material on the Android device by making apps The key material from application processes and from the Android device as a whole. Mitigates unauthorized use of key material outside of the Android device by preventing extraction of

This document goes over when and how to use the Android KeystoreĪndroid Keystore system protects key material from unauthorized use. Security Features section for more information.ĪPI, introduced in Android 4.0 (API level 14) the Android Keystore providerįeature, introduced in Android 4.3 (API level 18) and the Restricting keys to be used only in certain cryptographic modes. How keys can be used, such as requiring user authentication for key use or Moreover, it offers facilities to restrict when and Keystore, they can be used for cryptographic operations with the key material To make it more difficult to extract from the device. The Android Keystore system lets you store cryptographic keys in a container
