Day-0 for the IETF 103 hackathon was really fun. We had two first-timers who worked pretty hard. It was really an intense moment on Day 1. Everyone was busy with their projects. I should admit it was pretty intense. Our first pull request was already merged by Muzaffar from the TLS 1.3 whereas kheshav had the testing part to complete for HTTP 451. I already send a pull request for SSH for the NetSSH Ruby library. We discussed a lot on implementation and testing part. Nathan, Jeremy, and Rahul also worked heavily on the TLS 1.3 implementation. For the IETF 103, we decide to skip the interoperability testing and focus more on implementation.
When it comes to goodies, WolfSSL congratulated us for a good job and sent us several goodies and other stuff.
However, on the SSH side, we have to deprecate RC4 in several projects such as NetSSH and JSCH, a JAVA library. On TLS 1.3, SNI added to Httperf, a TLS 1.3 library is still on progress on CSharp and LUA. We also have one module for Drupal and Django for HTTP 451.
Today is the first day for the IETF 103 remote hackathon in Mauritius. The cyberstorm.mu team is ready to lead and participate in all the three tracks as champions for the event. We have the TLS 1.3, SSH and HTTP 451. All the three tracks are lead by cyberstorm.mu as champions.
Our first timers for the IETF 103 hackathon is Kheshav Sewnundun, creator of XpressLiteCoin.com and Devops Engineer at Linkbynet Indian Ocean. We also have Diresh Soomirtee, Junior system administrator at Linkbynet Indian Ocean.
Prior before the hackathon, we did some shopping for the basic amenities. We reached at the quarter at a Mauritius Villas, a bungalow in Pointe Aux Piments at around 13:00 hrs. The network was set up with two different ISPs in case of breakdown, we can still be live during the hackathon.
We also celebrated Kifah’s birthday during the hackathon.
At cyberstorm.mu, it’s always the pool that brings more relaxing time. We are also in the Halloween week and some guys even brought their Halloween costumes and went swimming inside the pool.
Most of us already started working on our projects and some pull requests already sent. More testing on progress as well as creating of several patches. We even need to have a discussion on open source licensing to make sure that there are incompatibility issues between different licenses. We made a plan for the three tracks we are championing and it looks to start pretty fine.
By this time, it’s already late here. I really need some sleep to start day 1 for the IETF 103 hackathon 🙂
I should say that we were already planning about our next event, hence, a hackathon on Operation KSK-ROLL by the cyberstorm.mu team which was pretty easy, important and successful. Dr. Till Jaeger congratulate us for creating the cyberstorm.mu team. Several pull requests sent to many repositories to encourage developers to adopt the new key.
What is Operation KSK-ROLL?
At cyberstorm.mu all Non-IETF hackathons are usually given a name. This time for the KSK rollover hackathon we have chosen 'Operation KSK-Roll'. Operation KSK-ROLL has been started to make sure that software is up-to-date with the new KSK key.
What is the KSK rollover?
The DNS KSK Rollover happened on 11 October at 11:00 UTC. Rolling the KSK means generating a new key cryptographic key pair (public and private key).
What are those keys?
The public key is distributed to those who operate valid DNS resolvers such as ISPs, network administrators, system integrators etc.. whilst, the private key is kept secret.
If its secret, why do we need to generate another secret key?
For security purpose, the secret key is generated anew and this ensures that DNS resolvers have a more robust security layer on top of the DNS AKA: DNSSEC
What are DNS resolvers?
All websites, example tunnelix.com which is a domain name is behind an IP Address. For your browser to be able to resolve the website, a DNS resolver which is located at several parts of the world will identify the IP with the domain name. Consequently, this will render the website on your browser.
What is DNSSEC?
As mentioned previously, DNSSEC (DNS Security) is a layer added by ICANN to ensure by means of cryptographic keys to ensure an online protection from the provider of the root domain name to your browser.
How will you know if a website is DNSSEC signed?
There is a tool by VeriSign lab which provides DNSSEC Analyzer. You can enter the name of the domain, say tunnelix.com which will analyze the domain show you the public key and the chain from the . (dot), com and tunnelix.com.
Is there another way to verify it?
Yes, you can use the nslookup or dig tool to check it. In the case of the dig tool here is a screenshot.
What is the logic behind the DIG command?
Some years back (the Year 2015), I explained the anatomy of the dig command. You can view more details about the blog post called "Anatomy of a simple dig result".
What is the role of the KSK?
The KSK private key is used to generate a digital signature for the ZSK. In fact, the KSK public key is stored in the DNS to be used for authenticating the ZSK. So, the KSK is a key to sign another key for the ZSK. That is why it is called the "Key Signing Key".
So, what is the ZSK?
The ZSK (Zone Signing Key) is another private-public key pair which is used to generate a digital signature known as RRSIG ( Resource Record Signature). The RRSIG in itself is a digital signature for each RRSET (Resource Record Sets) in a zone. In fact, the ZSK is stored in the domain name system to authenticate the RRset.
What are RRsets?
RRsets (Resource Record sets) is a group of records DNS Record Set (RRsets) with the same record type, for example, all DNS A records are one RRset.
My contributions for KSK ROLL
Please follow me on my Github account. One of the repositories is Nagval which is a plugin to check the validity of one of more DNSSEC domains.
For more information about DNSSEC, ZSK, PSK etc, I would advise to check out Cloudflare which provided a good source of information.
Cyberstorm.mu continue to go beyond and further with innovations and more ideas to protect and secure the Internet. We believe that though we are a small team will be able to recruit more people who are strongly interested in developing their skills to strive for excellence.
I also wish to seize this opportunity to thanks Manuv Panchoo for designing the logo of tunnelix.com

Some pictures during the informal event:
OpenSource licensing with Dr. Till Jaeger and cyberstorm.mu
I should admit that it was really an informal meeting over some beers, juice, Dame-Blanche, and Pizzas with Dr. Till Jaeger. It was very fruitful and amazing to the team. We received lots of advice for ourselves as well as for the cyberstorm.mu team. Some days back, the National Computer Board conducted a workshop on Opensource licensing which where Dr. Till Jaeger was the main resource person to deliver this workshop. Thanks to the National Computer Board for making this event a success. Cyberstorm.mu members were also invited to the event.
We have also welcomed Rahul Golam for joining cyberstorm.mu team and looking forward to work together. I seized this opportunity to announce that cyberstorm.mu is proud to announce it’s the official logo. Thanks to the hard work of the team.
We are for free and opensource software. We are presenting Mauritius worldwide in the IT sector. We are a Linux and Open source group which is going further and beyond. We believe in collaborative work and team spirit. We believed in running codes. We strived for excellence. We have contributed codes in several popular applications. We have worked on Internet-Drafts. We participate heavily in Hackathons.
The next step of cyberstorm.mu is championing several tracks for the IETF 103 hackathon remotely at Bangkok, Thailand. We have been welcomed by many people both from Mauritius and overseas, even from Silicon Valley, USA. No wonder, our past achievements is now a new step to reach today’s objectives – To focus heavily on research and development. Loganaden Velvindron from cyberstorm.mu mentioned on his Medium blog about the change cyberstorm.mu want to achieve: “The namecyberstorm.mu is an interesting one. It’s about change coming. Don’t get me wrong: I still love hacking. For me, hacking is about finding clever solutions to problems.” The youngest guy from the team is also going to participate in the IETF 103 hackathon.
