Increases security of communication by adding XML Digital Signature (XMLDSig) to XML messages

Highlighted features

XMLDSig Adapter Module adds digital signature (XMLDSig) to XML messages in SAP PI/PO system. The messages are signed with X.509 private key stored in AS Java Keystore. X.509 public certificate is always attached to the message, so that the signature can be easily validated by a receiver.

Keystore Integration

Store your private keys and X.509 certificates securely in AS Java Keystore


Configure the module to use any of the digest and signature methods supported by your SAP AS Java System

No Programming Required

Add a digital signature to your message in just few minutes in Integration Builder

Easy Installation

Just deploy XMLDSig Adapter Module into your system to start using it!



Download the demo version and check if the Adapter Module fulfills your requirements.

Limitations: The demo version works only with the provided demo certificate (demo.p12 included in the zip archive, password !nDEV0).


The solution is delivered as an Adapter Module EAR file (Enterprise Application Archive).

Extract EAR file from the provided ZIP archive and deploy it into your SAP PI/PO system as described in the guide.

You’ll need SAP NetWeaver Developer Studio (NWDS, version >= 7.31) or access to SUM (Software Update Manager) to deploy the solution into your system.

System requirements

version >= 7.31

System JDK
version >= 1.6 (Java 6)


  1. Import the required Certificate and Key (X.509) into AS Java Key Storage as described here (for the demo version, import the PKCS#12 file included in ZIP archive: demo.p12, password !nDEV0).
  2. Open a receiver Communication Channel in either NWDS or Integration Directory in Change Mode
  3. Switch to Module(s) tab
  4. Add XMLDSig module before the standard CallSapAdapter module: enter XMLDSig as Module Name, select Local Enterprise Bean as Type and enter a Module Key (e.g. dsig)
  5. Specify the parameters in Module Configuration section (see Parameters section below for details)
  6. Save and Activate your changes
