IvParameterSpec

extends Object
implements AlgorithmParameterSpec

java.lang.Object
↳	javax.crypto.spec.IvParameterSpec

Class Overview

The algorithm parameter specification for an initialization vector.

Public Constructors
	IvParameterSpec(byte[] iv) Creates a new `IvParameterSpec` instance with the bytes from the specified buffer iv used as initialization vector.
	IvParameterSpec(byte[] iv, int offset, int byteCount) Creates a new `IvParameterSpec` instance with `byteCount` bytes from the specified buffer `iv` starting at `offset`.

Public Methods
byte[]	getIV() Returns a copy of the initialization vector data.

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() Called before the object's memory is reclaimed by the VM.
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.

Since: API Level 1

Creates a new IvParameterSpec instance with the bytes from the specified buffer iv used as initialization vector.

iv	the buffer used as initialization vector.

NullPointerException	if the specified buffer is null.

Since: API Level 1

Creates a new IvParameterSpec instance with byteCount bytes from the specified buffer iv starting at offset.

IllegalArgumentException	if the specified buffer is null or `offset` and `byteCount` do not specify a valid chunk in the specified buffer.
ArrayIndexOutOfBoundsException	if `offset` or `byteCount` are negative.

Since: API Level 1

Returns a copy of the initialization vector data.
