KeyPairGeneratorSpec

extends Object
implements AlgorithmParameterSpec

java.lang.Object
↳	android.security.KeyPairGeneratorSpec

Class Overview

This provides the required parameters needed for initializing the KeyPairGenerator that works with Android KeyStore facility. The Android KeyStore facility is accessed through a KeyPairGenerator 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.

After generation, the keyStoreAlias is used with the getEntry(String, java.security.KeyStore.ProtectionParameter) interface to retrieve the PrivateKey and its associated Certificate chain.

The KeyPair generator will create a self-signed certificate with the subject as its X.509v3 Subject Distinguished Name and as its X.509v3 Issuer Distinguished Name along with the other parameters specified with the KeyPairGeneratorSpec.Builder.

The self-signed X.509 certificate may be replaced at a later time by a certificate signed by a real Certificate Authority.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
