This talk is about reverse engineering a proprietary network protocol and then creating my own implementation. The protocol covered is the RTMP protocol used by Adobe flash, and this new implementation is part of the Gnash project. The talk will cover the tools used to take binary data apart, capture the data, and techniques I use for decoding unknown formats. It will also cover how to reverse reverse reverse engineer a proprietary protocol and create a new implementation of this protocol. The video will be shown at the end of the talk.
