pysap - Python library for crafting SAP’s network protocols packets

Version v0.1.20.dev0 (Installation)


SAP Netweaver and SAP HANA are technology platforms for building and integrating SAP business applications. Communication between components uses different network protocols and some services and tools make use of custom file formats as well. While some of them are standard and well-known protocols, others are proprietaries and public information is generally not available.

pysap is an open source Python 2 library that provides modules for crafting and sending packets using SAP’s NI, Diag, Enqueue, Router, MS, SNC, IGS, RFC and HDB protocols. In addition, support for creating and parsing different proprietary file formats is included. The modules are built on top of Scapy and are based on information acquired at researching the different protocols, file formats and services.


  • Dissection and crafting of the following network protocols:

    • SAP Network Interface (NI)
    • SAP Diag
    • SAP Enqueue
    • SAP Router
    • SAP Message Server (MS)
    • SAP Secure Network Connection (SNC)
    • SAP Internet Graphic Server (IGS)
    • SAP Remote Function Call (RFC)
    • SAP HANA SQL Command Network (HDB)
  • Client interfaces for handling the following file formats:

    • SAP SAR archive files
    • SAP Personal Security Environment (PSE) files
    • SAP SSO Credential (Credv2) files
  • Library implementing SAP’s LZH and LZC compression algorithms.

  • Automatic compression/decompression of payloads with SAP’s algorithms.

  • Client, proxy and server classes implemented for some of the protocols.

  • Example scripts to illustrate the use of the different modules and protocols.
