Sig-I/O (Berichten over sig-io)

Various SSL/TLS related sites and services

Mark Janssen — Fri, 24 Jan 2020 01:09:24 GMT

Upto this week (end January 2020), a friend of mine used to run a couple of SSL/TLS related websites (cipherli.st, certificatemonitor.org, ssldecoder.org) which I used quite frequently. Sadly he has decided to no longer host these sites, for reasons undisclosed. I've taken it apon me to host alternative versions of these services, as I myself use them a lot, and also think they shouldn't disappear from the internet.

Since I do not control the original domain-names, these services can now be found under the following new URL's:

https://ssldecoder.eu -- Print information about site-certificates or CSR's

https://sslmonitor.eu -- Get mail notifications about expiring certificates

https://cipherlist.eu -- Recommended TLS/SSL configurations for populair services

This was quite easy and quick to get running, as Raymii was so friendly to have all the source-code to these services on his github. I've made personal forks of the various repositories, where I will try to keep them somewhat maintained.

Contributions and additions are more then welcome, please visit the relevant sites for links to their github pages.

Sig-I/O now 9 years old, debian-lts sponsor for 3

This week marks the 9th year in Sig-I/O's existance. Looking back over the past nine years shows a nice growth in the number of clients and a collection of interesting assignments Sig-I/O has been involved in.

While the services that Sig-I/O provides have shifted somewhat over these 9 years, some have also remained the same, with some clients already with us from the very beginning. The past few years have been mostly about Managed Hosting, Linux-, Ansible- and Security-Consulting and since a few years also Training, via a partnership with IT-Gilde which has been going steady for 3 years now.

This month also marks the 3rd complete year that Sig-I/O has been a sponsor of the Debian LTS project. This sponsorship has also been renewed for the coming year. The Debian LTS project could use some more sponsors, so if your organisation uses Debian servers extensively, it might be beneficial to sponsor them. Debian LTS will support Debian 7 until May of 2019, and will then continue with LTS support for Debian 8 into the 2020's

The next few years will undoubtedly bring many more interesting challenges and opportunities.

Sig-I/O sluit zich aan bij de ITGilde Coöperatie

Vandaag, 2 september 2015, heeft Sig-I/O Automatisering zich aangesloten bij de ITGilde Coöperatie.

Door het aansluiten bij ITGilde Coöperatie hebben klanten van Sig-I/O automatisering toegang tot de kennis en kunde van een grote groep hoogwaardige freelance Unix en Linux specialisten.

Het volgende werd hierover op de ITGilde website geschreven

Vandaag verwelkomt ITGilde Mark Janssen als 49ste lid van ITGilde. Naast
ITGilde is Mark actief bij de NLUUG en RevSpace . Het motto van Mark
is: “over 5 minuten is het opgelost”.

De reden voor Mark om aan te sluiten bij ITGilde is een kwalitatief
hoogwaardig netwerk met een hoge frequentie van vakgerelateerde
bijeenkomsten; gericht op Linux/Unix ondernemers.

Daarnaast werkt Mark meer dan fulltime en wil toch meer klanten kunnen
helpen dan hij nu aankan. ITGilde is daar de oplossing voor: “ik kan
mezelf maar 1 keer inzetten maar met ITGilde beschik ik nu over een pool
van goede technische Unix/Linux specialisten!”

Welkom Mark!
