[BOUNTY] Community Improvement Bounty - libp2p - Wireshark libp2p Lua dissectors

Wireshark libp2p Lua dissectors

We need to x-ray into the wire. Help us build mature Wireshark dissectors and get 2750 EUR! 🤑

See devgrant 16 in the libp2p/devgrants tracker: libp2p/devgrants#16

The brief for this bounty can be found here: https://github.com/libp2p/devgrants/blob/master/016-wireshark-lua-dissectors.md.

How to qualify

We know you are an amazingly talented hacker, but also recognise that developing a Wireshark dissectors for all of libp2p protocols is not feasible in 2-3 hackathon days! For that reason, we're going to tightly scope this to what we believe is ambitious, but possible.

There has been a previous attempt, but our road block has always been decryption. We'd like you to focus on that. Without decryption, the dissector has limited usability as it won't support debugging live networks.

You'd earn the reward if you:

1. Fork go-libp2p-secio to dump its symmetric keys when a build tag (e.g. dumpkeys) and an environment variable are both activated (LIBP2P_SECIO_KEYLOG=<path>).
2. Build a SecIO Wireshark dissector that dissects the SecIO protocol itself.
3. That dissector should tail the keylog file, and use the symmetric key associated with a peer at an ip:port to decrypt that connection.
4. Build an mplex dissector (mplex framing is super simple) that operates on a decrypted payload.

Main challenges we expect you to encounter:

• Parsing Protobuf messages. There is no native protobuf library in Lua. You might want to call out to C. See: this post and Swig.
• Crypto operations. You can probably use OpenSSL and get inspiration from secio.lua.

Read the devgrant brief referenced above, and review all the past work referenced in resources.

Judging Criteria

1. Completeness, correctness, cleanliness and maintainability of code.
2. Documentation / code comments.
3. It actually works, and you can demo it.

Prizes

1. 1000 EUR via Community Improvement Bounties fund.
2. 1000 EUR via Protocol Labs.
3. 750 EUR via the Ethereum Foundation.

I would like to chose this bounty to work on.

@michaelvonorov find me! I’m at the venue.

This one has been claimed by @michaelvoronov and is underway! 🙌

The repo has been renamed to libp2p-dissector, since it supports not only secio now.

Is this still open in some way? Can I talk to someone about this? I've written a Wireshark dissector before, and would find it interesting to write another.
