Hi,
I'm currently using the Visibroker for Java CORBA orb with ssl. It
comes with a set of java classes and a native shared library.
Unfortunately the international version of the dll only supports export
strength encryption.
I'm considering the feasibility of using the dll's that come with
SSLeay (via a wrapper) to bypass this, providing strong encryption and
adding extra functionality (choice of ciphers etc.)
The native interface appears to encapsulate a lot of the functionality
- handshake etc, in a pretty simple fashion (see the javap output
below). So it might not be a huge amount of work to produce a
substitute dll (famous last words :). I was wondering if anyone could
comment on the this, or if anything similar has already been attempted?
Cheers,
Luke.
