RE: AES pointers needed..

Dennis Morgan:

 Hi,
 what i am trying to achieve is to encrypt a plain ascii text message

 Which will be transmitted via a udp or tcp.

 The application which its been implemented for is for a security product..

 regards
 Dennis

Do you have a shared secret that only the client and server know?

Why not just secure the TCP connection itself using SSL/TLS?

And you failed to state what mode of operation you plan to use despite the
fact that you were specifically asked. Please don't take this the wrong way,
but just like bridges have to be designed and built by people who know
something about bridges in order to be safe and reliable, so must security
products be designed and built by people who know something about security.
If you don't even know how to ask for what you want or what requirements
need to be stated to be pointed to a solution, it is literally impossible
for your solution to be reliable. A bridge cannot be reliable if it wasn't
designed and specified by experts in bridge design. Period.

Hi Dennis,

 I am presently looking at implementing AES 256bit into an
 application which I am working on... Is it possible to do it
 with OpenSSL?
It depends on what you want to accomplish, and the mode of operation
in which AES-256 will be operating. Can you offer more details?

You could use libeay alone (not linking in libssl), and that would
include an implementation of AES256.
