HTTPS Configuration for Messaging

When configuring HTTPS for message exchange, you must handle the ABAP and Java parts differently.

For the ABAP proxies, you use transaction SM59 to configure the destinations pointing to the Integration Server to use HTTPS.

For the Advanced Adapter Engines and the Java proxies, HTTPS communication is set generically using the following parameter in the exchange profile (more information: HTTP and SSL).

To be able to send and receive messages using HTTPS/SSL:

AS Java must first be configured to support HTTPS/SSL.
More information: Transport Layer Security on the AS Java.
AS ABAP must first be configured to support HTTPS/SSL.
More information: Using the Secure Sockets Layer Protocol with AS ABAP.

With HTTPS, you can use basic authentication with username and password, as well as authentication using client certificates. If you want to use client certificate authentication, additional private keys and public certificates are required for each user.
