If your app targets Android 9 (API level 28) or lower, inspect the boolean return.

If your app targets Android 10 (API level 29) or higher, inspect the return.

The next step depends on your app’s target SDK version: To check whether the feature is enabled for a key, obtain aįor the key. Modes, padding schemes, and digests the key is authorized to be used with. Only if the device's secure hardware supports the particular combination of key algorithm, block Keystore keys on the Android device, but it can't extract them from the device. If the Android OS is compromised or anĪttacker can read the device's internal storage, the attacker might 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

Key material can be bound to the secure hardware of the Android device, such as the.

If the app's process is compromised, the attacker might be able to use the app's keys but can'tĮxtract 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 that carries out the cryptographic operations.

Key material never enters the application process.

Key material of Android Keystore keys is protected from extraction using two Specify the authorized uses of their keys and then enforcing those restrictions Of key material within the Android device by making apps Second, the keystore system reduces the risk of unauthorized use The key material from application processes and from the Android device as a Outside the Android device by preventing the extraction of First, it reduces the risk of unauthorized use of key material from

The Android Keystore system protects key material from unauthorized use in two

This document goes over when and how to use the Android Keystore See theĪPI, 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 use only in certain cryptographic modes. Also, the keystore system lets you restrict whenĪnd how keys can be used, such as requiring user authentication for key use or Keystore, you can use them for cryptographic operations, with the key material To make them more difficult to extract from the device. The Android Keystore system lets you store cryptographic keys in a container
