Method Detail

getSymmetricAlgorithm

public int getSymmetricAlgorithm(org.bouncycastle.openpgp.operator.PBEDataDecryptorFactory dataDecryptorFactory)
                          throws PGPException
Return the symmetric key algorithm required to decrypt the data protected by this object.
Parameters:
dataDecryptorFactory - decryptor factory to use to recover the session data.
Returns:
the identifier of the encryption algorithm used to encrypt this object.
Throws:
PGPException - if the session data cannot be recovered.

getDataStream

public java.io.InputStream getDataStream(org.bouncycastle.openpgp.operator.PBEDataDecryptorFactory dataDecryptorFactory)
                                  throws PGPException
Open an input stream which will provide the decrypted data protected by this object.
Parameters:
dataDecryptorFactory - decryptor factory to use to recover the session data and provide the stream.
Returns:
the resulting decrypted input stream, probably containing a sequence of PGP data objects.
Throws:
PGPException - if the session data cannot be recovered or the stream cannot be created.
