Method Summary

Modifier and TypeMethod and Description
public int
getAlgorithm()

Overrides org.bouncycastle.openpgp.PGPEncryptedData.getAlgorithm.

Return the symmetric encryption algorithm that is used by the packet.
public InputStream

Returns:

the resulting decrypted input stream, probably containing a sequence of PGP data objects.
getDataStream(PBEDataDecryptorFactory
decryptor factory to use to recover the session data and provide the stream.
dataDecryptorFactory)

Open an input stream which will provide the decrypted data protected by this object.
