Class PGPPublicKeyRing

java.lang.Object

org.bouncycastle.openpgp.PGPKeyRing

org.bouncycastle.openpgp.PGPPublicKeyRing

All Implemented Interfaces:

java.lang.Iterable<PGPPublicKey>

Direct Known Subclasses:

BcPGPPublicKeyRing, JcaPGPPublicKeyRing

public class PGPPublicKeyRing
extends PGPKeyRing
implements org.bouncycastle.util.Iterable<PGPPublicKey>

Class to hold a single master public key and its subkeys.

Often PGP keyring files consist of multiple master keys, if you are trying to process or construct one of these you should use the PGPPublicKeyRingCollection class.

Method Detail

getPublicKey

public PGPPublicKey getPublicKey()

Return the first public key in the ring.

Specified by:

getPublicKey in class PGPKeyRing

Returns:

PGPPublicKey

getPublicKey

public PGPPublicKey getPublicKey(long keyID)

Return the public key referred to by the passed in keyID if it is present.

Specified by:

getPublicKey in class PGPKeyRing

Parameters:

keyID - the full keyID of the key of interest.

Returns:

PGPPublicKey with matching keyID, null if it is not present.

getPublicKey

public PGPPublicKey getPublicKey(byte[] fingerprint)

Return the public key with the passed in fingerprint if it is present.

Specified by:

getPublicKey in class PGPKeyRing

Parameters:

fingerprint - the full fingerprint of the key of interest.

Returns:

PGPPublicKey with the matching fingerprint, null if it is not present.

getKeysWithSignaturesBy

public java.util.Iterator<PGPPublicKey> getKeysWithSignaturesBy(long keyID)

Return any keys carrying a signature issued by the key represented by keyID.

Specified by:

getKeysWithSignaturesBy in class PGPKeyRing

Parameters:

keyID - the key id to be matched against.

Returns:

an iterator (possibly empty) of PGPPublicKey objects carrying signatures from keyID.

getPublicKeys

public java.util.Iterator<PGPPublicKey> getPublicKeys()

Return an iterator containing all the public keys.

Specified by:

getPublicKeys in class PGPKeyRing

Returns:

Iterator

iterator

public java.util.Iterator<PGPPublicKey> iterator()

Support method for Iterable where available.

Specified by:

iterator in interface java.lang.Iterable<PGPPublicKey>

getEncoded

public byte[] getEncoded()
                  throws java.io.IOException

Specified by:

getEncoded in class PGPKeyRing

Throws:

java.io.IOException

getEncoded

public byte[] getEncoded(boolean forTransfer)
                  throws java.io.IOException

Return an encoding of the key ring, with trust packets stripped out if forTransfer is true.

Parameters:

forTransfer - if the purpose of encoding is to send key to other users.

Returns:

a encoded byte array representing the key.

Throws:
