The UA SDK is a C++ library that supports you in writing portable C++ OPC UA Servers and Clients. The UA SDK actually consists of two SDKs, a Server SDK and a Client SDK. Both use the same UA Base Library which does all the C++ encapsulation of the raw ANSI C types that are defined in the OPC UA Communication Stack by the OPC Foundation (http://www.opcfoundation.org).

A SDK simplifies the UA stack APIs, implements common UA functionality needed in most or all UA applications, provides base functionality and helper functions, implements the security handling and provides samples for common use cases.
The C++ OPC UA Client SDK provides a C++ class library used to develop OPC UA Clients.

Portability is guaranted by a concept of portability layers. The rest of the code is generic code that is independent of the operating system and can be reused without any changes. The UA Communication Stack has a portability layer that encapsulates already the most important operating system calls like Sockets, Semaphores, Mutexes, Threads, etc. The Ua Base Library is built on top of this UA Stack and does not need any further portability layer. The same applies for the software layers built on top of the UA Base Library.

The additional base modules UA PKI Library and UA XML Library are further abstraction layers that encapsulate special software components. We use the Open Source projects OpenSSL and LibXML2 to implement that functionality, because it's good software, it's ported already to several operating systems and they don't have restrictive licenses like the GPL. But if your company polices don't allow to use any Open Source for whatever reason it's possible to change this without a need to change anything else in the upper layers of the SDK or your application. Aside from simplifying the usage of this libraries this was main reason why we encapsulated this functionality with our own interface and don't use the Open Source code directly in our SDKs.
