Method Detail

getKeyID

public long getKeyID()

Return the keyID for the key used to encrypt the data.

Returns:

long

getSymmetricAlgorithm

public int getSymmetricAlgorithm(PublicKeyDataDecryptorFactory 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.

getSessionKey

public PGPSessionKey getSessionKey(PublicKeyDataDecryptorFactory dataDecryptorFactory)
                            throws PGPException

Return the symmetric session key required to decrypt the data protected by this object.

Parameters:

dataDecryptorFactory - decryptor factory to use to recover the session data.

Returns:

session key used to decrypt the data protected by this object

Throws:

PGPException - if the session data cannot be recovered.

getDataStream

public java.io.InputStream getDataStream(PublicKeyDataDecryptorFactory 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 input stream

Throws:

PGPException - if the session data cannot be recovered or the stream cannot be created.

getDataStream

public java.io.InputStream getDataStream(SessionKeyDataDecryptorFactory dataDecryptorFactory)
                                  throws PGPException

Deprecated.

will be removed in 1.74, use PGPEncryptedDataList.extractSessionKeyEncryptedData() and then apply the dataDecryptorFactory.

Throws:

PGPException
