DrbgParameters.NextBytes | API reference

public static final class DrbgParameters.NextBytes
extends Object implements SecureRandomParameters

DRBG parameters for random bits generation. It is used in SecureRandom.nextBytes(byte[],SecureRandomParameters).

Summary

Public methods
`byte[]`	`getAdditionalInput()` Returns the requested additional input.
`boolean`	`getPredictionResistance()` Returns whether prediction resistance is requested.
`int`	`getStrength()` Returns the security strength requested in bits.

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 methods

getAdditionalInput

public byte[] getAdditionalInput ()

Returns the requested additional input.

Returns
`byte[]`	the requested additional input, `null` if not requested. A new byte array is returned each time this method is called.

getPredictionResistance

public boolean getPredictionResistance ()

Returns whether prediction resistance is requested.

Returns
`boolean`	whether prediction resistance is requested

getStrength

public int getStrength ()

Returns the security strength requested in bits.

Returns
`int`	the strength requested, or -1 if the effective strength should be used.
