* Feature for {@link #getSystemAvailableFeatures} and {@link #hasSystemFeature}:
* The device has a StrongBox hardware-backed Keystore.
* Feature for {@link #getSystemAvailableFeatures} and
* {@link #hasSystemFeature(String, int)}: If this feature is supported, the device implements
* the Android Keystore backed by an isolated execution environment. The version indicates
* which features are implemented in the isolated execution environment:
* <ul>
* <li>100: Hardware support for ECDH (see {@link javax.crypto.KeyAgreement}) and support
* for app-generated attestation keys (see {@link
* android.security.keystore.KeyGenParameterSpec.Builder#setAttestKeyAlias(String)}).
* <li>41: Hardware enforcement of device-unlocked keys (see {@link
* android.security.keystore.KeyGenParameterSpec.Builder#setUnlockedDeviceRequired(boolean)}).
* <li>40: Support for wrapped key import (see {@link
* android.security.keystore.WrappedKeyEntry}), optional support for ID attestation (see {@link
* android.security.keystore.KeyGenParameterSpec.Builder#setDevicePropertiesAttestationIncluded(boolean)}),
* attestation (see {@link
* android.security.keystore.KeyGenParameterSpec.Builder#setAttestationChallenge(byte[])}),
* AES, HMAC, ECDSA and RSA support where the secret or private key never leaves secure
* hardware, and support for requiring user authentication before a key can be used.
* </ul>
* This feature version is guaranteed to be set for all devices launching with Android 12 and
* may be set on devices launching with an earlier version. If the feature version is set, it
* will at least have the value 40. If it's not set the device may have a version of
* hardware-backed keystore but it may not support all features listed above.
