   +----javax.crypto.spec.IvParameterSpec

public class IvParameterSpec
extends Object
implements AlgorithmParameterSpec
This class specifies an initialisation vector (IV). IVs are used by ciphers in feedback mode, e.g., DES in CBC mode.

Variable Index

 o ident

Constructor Index

 o IvParameterSpec(byte[])
Uses the bytes in iv as the IV.
 o IvParameterSpec(byte[], int, int)
Uses the first len bytes in iv, beginning at offset, as the IV.

Method Index

 o getIV()
Returns the initialisation vector (IV).

Variables

 o ident
 public static final String ident

Constructors

 o IvParameterSpec
 public IvParameterSpec(byte iv[])
Uses the bytes in iv as the IV.

Parameters:
iv - the buffer with the IV
 o IvParameterSpec
 public IvParameterSpec(byte iv[],
                        int offset,
                        int len)
Uses the first len bytes in iv, beginning at offset, as the IV.

Parameters:
iv - the buffer with the IV
offset - the offset in iv, where the IV starts
len - the number of IV bytes

Methods

 o getIV
 public byte[] getIV()
Returns the initialisation vector (IV).

Returns:
the initialisation vector (IV)
