KeyStoreParameter

Kotlin |Java

public final class KeyStoreParameter
extends Object implements KeyStore.ProtectionParameter

java.lang.Object
↳	android.security.KeyStoreParameter

This class was deprecated in API level 23.
Use KeyProtection instead.

This provides the optional parameters that can be specified for KeyStore entries that work with Android KeyStore facility. The Android KeyStore facility is accessed through a KeyStore API using the AndroidKeyStore provider. The context passed in may be used to pop up some UI to ask the user to unlock or initialize the Android KeyStore facility.

Any entries placed in the KeyStore may be retrieved later. Note that there is only one logical instance of the KeyStore per application UID so apps using the sharedUid facility will also share a KeyStore.

Keys may be generated using the KeyPairGenerator facility with a KeyPairGeneratorSpec to specify the entry's alias. A self-signed X.509 certificate will be attached to generated entries, but that may be replaced at a later time by a certificate signed by a real Certificate Authority.

`class`	`KeyStoreParameter.Builder` This class was deprecated in API level 23. Use `KeyProtection.Builder` instead.

Public methods
`boolean`	`isEncryptionRequired()` This method is deprecated. Data at rest encryption is enabled by default. If extra binding to the lockscreen credential is desired, use `.Builder#setUserAuthenticationRequired(boolean)`. This flag will be ignored from Android S.

          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public methods

isEncryptionRequired

Added in API level 18

public boolean isEncryptionRequired ()

This method is deprecated.
Data at rest encryption is enabled by default. If extra binding to the lockscreen credential is desired, use .Builder#setUserAuthenticationRequired(boolean). This flag will be ignored from Android S.

Returns true if the KeyStore entry must be encrypted at rest. This will protect the entry with the secure lock screen credential (e.g., password, PIN, or pattern).

Note that encrypting the key at rest requires that the secure lock screen (e.g., password, PIN, pattern) is set up, otherwise key generation will fail. Moreover, this key will be deleted when the secure lock screen is disabled or reset (e.g., by the user or a Device Administrator). Finally, this key cannot be used until the user unlocks the secure lock screen after boot.

Returns
`boolean`
