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

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

Inherited Methods

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<? extends Object>	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 len bytes from the specified buffer iv starting at offset.

iv	the buffer used as initialization vector.
offset	the offset to start in the buffer.
len	the length of the data.

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

Since: API Level 1

Returns a copy of the initialization vector data.
