SAP Netweaver is a technology platform for building and integrating SAP business applications. Communication between components uses different network protocols. While some of them are standard and well-known protocols, others are proprietaries and public information is not available.

pysap is a Python library that provides modules for crafting and sending packets using SAP's NI, Message Server, Router, RFC, SNC, Enqueue and Diag protocols. The modules are build on top of Scapy and are based on information acquired at researching the different protocols and services.

• 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.
