          org.bouncycastle.openpgp.PGPPublicKeyRing

    public class PGPPublicKeyRing

extends PGPKeyRing

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.

Constructor Summary
`PGPPublicKeyRing(byte[] encoding)`
`PGPPublicKeyRing(java.io.InputStream in)`

Method Summary
`void` `encode(java.io.OutputStream outStream)`
`byte[]` `getEncoded()`
`PGPPublicKey` `getPublicKey()` Return the first public key in the ring.
`PGPPublicKey` `getPublicKey(long keyID)` Return the public key referred to by the passed in keyID if it is present.
`java.util.Iterator` `getPublicKeys()` Return an iterator containing all the public keys.
`static PGPPublicKeyRing` `insertPublicKey(PGPPublicKeyRing pubRing, PGPPublicKey pubKey)` Returns a new key ring with the public key passed in either added or replacing an existing one.
`static PGPPublicKeyRing` `removePublicKey(PGPPublicKeyRing pubRing, PGPPublicKey pubKey)` Returns a new key ring with the public key passed in removed from the key ring.
