Method Summary

Modifier and Type	Method	Description
int	getAlgorithm()	Return the symmetric encryption algorithm that is used by the packet.
InputStream	getDataStream(SessionKeyDataDecryptorFactory dataDecryptorFactory)
int	getVersion()	Return the version number of the Encrypted Session Key Packet.
protected boolean	isPublicKeyEncrypted()	Whether this data was decrypted from a public-key (or otherwise already-recovered session key) rather than from a password (PBE).

Method Details

getAlgorithm

public int getAlgorithm()

Description copied from class: PGPEncryptedData

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

Overrides:

getAlgorithm in class PGPEncryptedData

Returns:

algorithm

getVersion

public int getVersion()

Description copied from class: PGPEncryptedData

Return the version number of the Encrypted Session Key Packet.

Overrides:

getVersion in class PGPEncryptedData

Returns:

version

getDataStream

public InputStream getDataStream(SessionKeyDataDecryptorFactory dataDecryptorFactory)
                          throws PGPException

Throws:

PGPException

isPublicKeyEncrypted

protected boolean isPublicKeyEncrypted()

Description copied from class: PGPSymmetricKeyEncryptedData

Whether this data was decrypted from a public-key (or otherwise already-recovered session key) rather than from a password (PBE). The CFB "quick check" is suppressed on the public-key / session-key path (it would only re-create the Mister-Zuccherato oracle and there is no multi-SKESK passphrase retry to drive); PBE keeps it. Overridden by PGPSessionKeyEncryptedData.

Overrides:
