2417205 - Enabling TLS 1.1 and 1.2 on SAP NetWeaver AS Java for outgoing connections

Symptom

  • You need to enable TLS 1.1 and 1.2 in your SAP NetWeaver Application Server Java for outgoing connections (i.e. NW Java as a client).
  • You may have read the SAP Notes 2284059 or 2503155, but you are not sure if your AS Java is already compliant with TLS 1.1 or 1.2.

Important: This article is applicable to communication scenarios that use the IAIK SSL library (mentioned in the SAP Notes above). If an application uses the underlying SAP JVM/JDK for TLS communication, it is needed to run SAP JVM 6.1.093 or higher patch (for NW 7.20, 7.3x, 7.40), or SAP JVM 8 (NW 7.5). In order to determine whether the application uses IAIK or the JVM, the traces of a TLS connection/error can be analyzed to check if they include iaik* packages or javax.net.ssl* packages. SAP JVM 4 (NW 7.0x) and 5 (NW 7.1x) do not support TLS 1.1/1.2.
