RedSplice

RedSplice is an application designed to help you learn various statistics about your network and enables you to reconstruct Internet usage sessions with a precise data package identification and management.

It is necessary to mention that the program is capable of decoding up to 25 protocols, a feature that can surely come in handy if you are working on a network app and require protocol-related data for example.

The tool can decode SSL traffic in both online and offline mode. While in the offline mode it needs a packet capture of the traffic and the SSL private keys, the online decoding is done via the run-time SSL proxy. The app can perform both passive and active decoding, yet the active one is available solely for the traffic generated by the local machine.

Then again, you should know that the app comes with a promiscuous packet capture function that allows you to analyze the traffic from an entire network segment.

Even though the amount of data gathered and displayed even in a small session can intimidate you, you should keep in mind that the utility allows you to filter the information quite easily. For starters, you can employ the advanced search function and look for data packets that you are interested in.

At the same time, you can use the Keyword Filtering, an option that enables you to view only the packets that are relevant to your project. Not only can you eliminate the data that you do not need, but you can also speed things up with the analysis, as the amount of data going through the filters is considerably reduced.

Regardless of whether you are looking for a tool to help you obtain valuable data to test an application or you just want to improve network security and performance using info about the packets of data sent and received, then RedSplice might come in handy.
