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.
is an open source Python 2 library that provides modules for crafting and sending packets
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

The spirit of this open source initiative is hopefully to help the community to alleviate some of the hindrances associated with the implementation of networking protocols and stacks, aiming at speeding up research and educational activities. By no means this package is meant to be used in production environments / commercial products. If so, we would advise to include it into a proper SDLC process.
The library was designed and developed by Martin Gallo from SecureAuth's Innovation Labs team, with the help of a large number of contributors.
