Doc from org.bouncycastle.openpgp.operator.PGPKeyEncryptionMethodGenerator.generate.

Generates a packet encoding the details of this encryption method.

Parameters
encAlgorithm:int

the encryption algorithm being used

sessionInfo:byte[]

session data generated by the encrypted data generator.

Returns:ContainedPacket

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

Exceptions
PGPException:
if an error occurs constructing the packet.

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:PublicKeyKeyEncryptionMethodGenerator

the current generator.
