Class PGPObjectFactory

java.lang.Object

org.bouncycastle.openpgp.PGPObjectFactory

All Implemented Interfaces:

java.lang.Iterable

Direct Known Subclasses:

BcPGPObjectFactory, JcaPGPObjectFactory

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

General class for reading a PGP object stream.

Note: if this class finds a PGPPublicKey or a PGPSecretKey it will create a PGPPublicKeyRing, or a PGPSecretKeyRing for each key found. If all you are trying to do is read a key ring file use either PGPPublicKeyRingCollection or PGPSecretKeyRingCollection.

This factory supports reading the following types of objects:

• PacketTags.SIGNATURE - produces a PGPSignatureList
• PacketTags.SECRET_KEY - produces a PGPSecretKeyRing
• PacketTags.PUBLIC_KEY - produces a PGPPublicKeyRing
• PacketTags.PUBLIC_SUBKEY - produces a PGPPublicKey
• PacketTags.COMPRESSED_DATA - produces a PGPCompressedData
• PacketTags.LITERAL_DATA - produces a PGPLiteralData
• PacketTags.PUBLIC_KEY_ENC_SESSION - produces a PGPEncryptedDataList
• PacketTags.SYMMETRIC_KEY_ENC_SESSION - produces a PGPEncryptedDataList
• PacketTags.ONE_PASS_SIGNATURE - produces a PGPOnePassSignatureList
• PacketTags.MARKER - produces a PGPMarker

PGPObjectFactory

public PGPObjectFactory(byte[] bytes,
                KeyFingerPrintCalculator fingerPrintCalculator)

Create an object factory suitable for reading PGP objects such as keys, key rings and key ring collections, or PGP encrypted data.

Parameters:

bytes - PGP encoded data.

fingerPrintCalculator - calculator to use in key finger print calculations.

Method Detail

nextObject

public java.lang.Object nextObject()
                            throws java.io.IOException

Return the next object in the stream, or null if the end of stream is reached.

Returns:

one of the supported objects - see class docs for details.

Throws:
