KeyRep

public class KeyRep
extends Object implements Serializable

java.lang.Object
↳	java.security.KeyRep

Standardized representation for serialized Key objects.

Note that a serialized Key may contain sensitive information which should not be exposed in untrusted environments. See the Security Appendix of the Serialization Specification for more information.

Summary

Public constructors
`KeyRep(KeyRep.Type type, String algorithm, String format, byte[] encoded)` Construct the alternate Key class.

Protected methods
`Object`	`readResolve()` Resolve the Key object.

Inherited methods

From class


        
          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 constructors

KeyRep

Added in API level 1

public KeyRep (KeyRep.Type type, 
                String algorithm, 
                String format, 
                byte[] encoded)

Construct the alternate Key class.

Parameters
`type`	`KeyRep.Type`: either one of Type.SECRET, Type.PUBLIC, or Type.PRIVATE
`algorithm`	`String`: the algorithm returned from `Key.getAlgorithm()`
`format`	`String`: the encoding format returned from `Key.getFormat()`
`encoded`	`byte`: the encoded bytes returned from `Key.getEncoded()`

Throws
`NullPointerException`	if type is `null`, if algorithm is `null`, if format is `null`, or if encoded is `null`

Protected methods

readResolve

Added in API level 1

protected Object readResolve ()

Resolve the Key object.

This method supports three Type/format combinations:

Type.SECRET/"RAW" - returns a SecretKeySpec object constructed using encoded key bytes and algorithm
Type.PUBLIC/"X.509" - gets a KeyFactory instance for the key algorithm, constructs an X509EncodedKeySpec with the encoded key bytes, and generates a public key from the spec
Type.PRIVATE/"PKCS#8" - gets a KeyFactory instance for the key algorithm, constructs a PKCS8EncodedKeySpec with the encoded key bytes, and generates a private key from the spec

Returns
`Object`	the resolved Key object

Throws
`ObjectStreamException`	if the Type/format combination is unrecognized, if the algorithm, key format, or encoded key bytes are unrecognized/invalid, of if the resolution of the key fails for any reason
