Class DrbgParameters.Instantiation

java.lang.Object

java.security.DrbgParameters.Instantiation

All Implemented Interfaces:

SecureRandomParameters

Enclosing class:

DrbgParameters

public static final class DrbgParameters.Instantiation
extends Object
implements SecureRandomParameters

DRBG parameters for instantiation.

When used in SecureRandom.getInstance(String, SecureRandomParameters) or one of the other similar getInstance calls that take a SecureRandomParameters parameter, it means the requested instantiate parameters the newly created SecureRandom object must minimally support. When used as the return value of the SecureRandom.getParameters() method, it means the effective instantiate parameters of the SecureRandom object.

Methods declared in class Object

clone, equals, finalize, getClass, hashCode, notify, notifyAll, wait, wait, wait

Modifier and Type	Method	Description
protected Object	clone()	Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
boolean	equals(Object o)	Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
protected void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. May cause performance issues, deadlocks and hangs.
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode()	Answers an integer hash code for the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.
final void	wait(long time, int frac)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Method Details

getStrength

public int getStrength()

Returns the security strength in bits.

Returns:

If used in getInstance, returns the minimum strength requested, or -1 if there is no specific request on the strength. If used in getParameters, returns the effective strength. The effective strength must be greater than or equal to the minimum strength requested.

getCapability

public DrbgParameters.Capability getCapability()

Returns the capability.

Returns:

If used in getInstance, returns the minimum capability requested. If used in getParameters, returns information on the effective prediction resistance flag and whether it supports reseeding.

getPersonalizationString

public byte[] getPersonalizationString()

Returns the personalization string as a byte array.

Returns:

If used in getInstance, returns the requested personalization string as a newly allocated array, or null if no personalization string is requested. The same string should be returned in getParameters as a new copy, or null if no personalization string is requested in getInstance.

toString

public String toString()

Returns a Human-readable string representation of this Instantiation.

Overrides:

toString in class Object

Returns:

the string representation
