Method Details
-
getSymmetricAlgorithm
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(PBEDataDecryptorFactory dataDecryptorFactory) throws PGPException Return the symmetric session key required to decrypt the data protected by this object.- Parameters:
dataDecryptorFactory
- decryptor factory used to recover the session data.- Returns:
- session key
- Throws:
PGPException
- if the session data cannot be recovered
-
getDataStream
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.
-
getDataStream
public InputStream getDataStream(SessionKeyDataDecryptorFactory dataDecryptorFactory) throws PGPException - Throws:
PGPException
