This document provides technical documentation about enhanced functionality and new APIs for the Extensible Messaging Gateway. The enhanced functionality comprises a new release of the Encryption/Decryption extension using certificates issued by Macao Post Office(DSC) and modified versions of existing components supporting the new extension. The new APIs enables applications developed in Delphi and any other programming language able to access the command line to invoke the Gateway services. The document first presents the scope of the Macao Data Exchange Gateway Project and the motivation for producing the deliverables presented in this report. Second, it specifies in detail the new extension for encrypting and decrypting messages. Third, it introduces the programming languages mostly used by applications deployed in Macao Government agencies, presents new APIs for invoking the Gateway services by applications developed in Delphi, and explains the use of two executable files for sending and receiving messages that can be invoked by any legacy application able to access the command line. Fourth, it enumerates the deployment components and explains the procedure for their deployment. Fifth, some conclusions are drawn. Finally, technical artifacts - like Java classes used by the Encryption extension, detailed and summarized lists of government applications and programming languages used by government agencies, Delphi APIs, Java classes for sending and receiving messages through the command line, and the new Gateway configuration file; are included in the appendices.
