How to check supported outbound cipher suites

This blog shows an easy way to determine supported outbound (client) cipher suites in PI / PO.

The key element to determine the supported cipher suites in an easy way is to use the internet tool “How’s my SSL?” (

The trick is, to setup a dummy ICO / IFlow using a receiver channel pointing to the api version of How’s my SSL. It’s easy to test it using the send test message

feature within PI / PO, but you can also use a synchronous sender channel (E. g. To call the interface with SOAP UI).

Attached you can find screenshot showing a dummy IFlow:



SOAP Receiver Channel:


Empty test message:


Result showing supported client cipher suites:


Attention: In PO Version (7.31 SP17) the HTTP_AAE adapter does not seem to use the IAIK library. We implemented SAP note 2284059

and get this result.






























“tls_version”:”TLS 1.0″


Further details about IAIK and TLS 1.2 can be found in this previous blog post: Outbound support for TLS 1.1/1.2

      Hi Markus,

      Congrats by blog.

      Recently SAP told me a cipher TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA aren't supported by Java Stack in PI 7.4. Is it working in your test?

      I can't apply note 2284059 in my PI.

      Hi Wilson,

      true answer above :-). Not possible by now.

      I am new to PI and would like to know how to create a sender for this scenario.

      Thanks Markus, works like a charm.

      Very handy if you don't have SAP Basis around.
