IvParameterSpec

The algorithm parameter specification for an initialization vector.

Summary

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`.

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() Invoked when the garbage collector has detected that this instance is no longer reachable.
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.

Public Constructors

public IvParameterSpec (byte[] iv)

Since: API Level 1

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

Parameters

iv	the buffer used as initialization vector.

Throws
