javax.crypto.spec
Class IvParameterSpec

java.lang.Object
  extended byjavax.crypto.spec.IvParameterSpec
All Implemented Interfaces:
AlgorithmParameterSpec

public class IvParameterSpec
extends Object
implements AlgorithmParameterSpec

This class specifies an initialization vector (IV). Examples which use IVs are ciphers in feedback mode, e.g., DES in CBC mode and RSA ciphers with OAEP encoding operation.

Since:
1.4

Constructor Summary
IvParameterSpec(byte[] iv)
          Uses the bytes in iv as the IV.
IvParameterSpec(byte[] iv, int offset, int len)
          Uses the first len bytes in iv, beginning at offset inclusive, as the IV.
 
Method Summary
 byte[] getIV()
          Returns the initialization vector (IV).

Constructor Detail

IvParameterSpec

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

Parameters:
iv - the buffer with the IV

IvParameterSpec

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

The bytes that constitute the IV are those between iv[offset] and iv[offset+len-1] inclusive.

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

getIV

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

Returns:
the initialization vector (IV)
