Method Detail

setSessionKeyObfuscation

public PublicKeyKeyEncryptionMethodGenerator setSessionKeyObfuscation(boolean enabled)

Controls whether to obfuscate the size of ECDH session keys using extra padding where necessary.

The default behaviour can be configured using the system property "", or else it will default to enabled.

Returns:

the current generator.

                            throws PGPException

Throws:

PGPException

generate

public ContainedPacket generate(int encAlgorithm,
                                byte[] sessionInfo)
                         throws PGPException

Description copied from class: PGPKeyEncryptionMethodGenerator

Generates a packet encoding the details of this encryption method.

Specified by:

generate in class PGPKeyEncryptionMethodGenerator

Parameters:

encAlgorithm - the encryption algorithm being used

sessionInfo - session data generated by the encrypted data generator.

Returns:

a packet encoding the provided information and the configuration of this instance.

Throws:

PGPException - if an error occurs constructing the packet.
