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	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() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Constructors

public RSAPublicKeyImpl (BigInteger n, BigInteger e)

Construct a key from its components. Used by the RSAKeyFactory and the RSAKeyPairGenerator.

Throws

InvalidKeyException

public RSAPublicKeyImpl (byte[] encoded)

Construct a key from its encoding. Used by RSAKeyFactory.

Throws

InvalidKeyException

Public Methods

public String getAlgorithm ()

Returns the algorithm to be used with this key.

Returns

the name of the algorithm associated with this key.

public BigInteger getModulus ()

Returns the modulus.

Returns

the modulus

public BigInteger getPublicExponent ()

Returns the public exponent.

Returns

the public exponent

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns

a string representation of the object.

Protected Methods

protected void parseKeyBits ()

Parse the key. Called by X509Key.

Throws

InvalidKeyException

protected Object writeReplace ()

Throws

ObjectStreamException
