This changes the encryption flags on the meterpreter session so that
it's 32 bits (and hence changes the packet header). This also supports
the idea that sessions may use encryption that isn't AES256, so the
flags field will ultimately indicate that. A type flag has been added so
that MSF knows the type that should be done on the wire.
At some point soon we'll add something that makes sure that the packet
encryption type always matches the encryption type expected in MSF, this
will hopefully avoid the risk of having packets injected into the stream
by external entities.
The Session GUID will identify active sessions, and is the beginning of
work that will allow for tracking of sessions that have come back alive
after failing or switching transports.
Small fix here to ensure that, even when boolean 'option' variables have a default value of 'true', that their current value is correctly reflected via the 'show options' command. This change should play fine with all other option variable types, I believe.
