Class PGPEncryptedDataList

java.lang.Object

org.bouncycastle.openpgp.PGPEncryptedDataList

All Implemented Interfaces:

java.lang.Iterable

public class PGPEncryptedDataList
extends java.lang.Object
implements org.bouncycastle.util.Iterable

A holder for a list of PGP encryption method packets and the encrypted data associated with them.

This holder supports reading a sequence of the following encryption methods, followed by an encrypted data packet:

• PacketTags.SYMMETRIC_KEY_ENC_SESSION - produces a PGPPBEEncryptedData
• PacketTags.PUBLIC_KEY_ENC_SESSION - produces a PGPPublicKeyEncryptedData

All of the objects returned from this holder share a reference to the same encrypted data input stream, which can only be consumed once.

Constructor Detail

PGPEncryptedDataList

public PGPEncryptedDataList(BCPGInputStream pIn)
                     throws java.io.IOException

Construct an encrypted data packet holder, reading PGP encrypted method packets and an encrytped data packet from the stream.

The next packet in the stream should be one of PacketTags.SYMMETRIC_KEY_ENC_SESSION or PacketTags.PUBLIC_KEY_ENC_SESSION.

Parameters:

pIn - the PGP object stream being read.

Throws:

java.io.IOException - if an error occurs reading from the PGP input.

Method Detail

get

public java.lang.Object get(int index)

Gets the encryption method object at the specified index.

Parameters:

index - the encryption method to obtain (0 based).

size

public int size()

Gets the number of encryption methods in this list.

isEmpty

public boolean isEmpty()

Returns true iff there are 0 encryption methods in this list.

getEncryptedDataObjects

public java.util.Iterator getEncryptedDataObjects()

Returns an iterator over the encryption method objects held in this list, in the order they appeared in the stream they are read from.

iterator

public java.util.Iterator iterator()

Support method for Iterable where available.

Specified by:

iterator in interface java.lang.Iterable
