About myself
My name is Ollivier Robert, also known as “roberto” or “Keltia” or “Keltounet” in various areas (social media, IRC), about 50 right now.
Working in computer science for more than 30 years now, mostly on UNIX-based systems like FreeBSD or Linux.
After being an Internet & Security Consultant at a small but well-known agency called HSC between 1994 and 1996, I was hired as Information Security Officer at a european agency called EUROCONTROL (or ECTL to make it shorter). Since then, I had several different positions there and now, I’m again Information Security Officer, now at Agency-level.
My résumé can be found here, more data on my LinkedIn site (see below).
Areas of interest
My main interests in life, after my family and friends are, in no particular order:
- Reading lots of books, mainly Sci-Fi and Fantasy ones. I’m a big fan of J.R.R. Tolkien but George R.R. Martin, C.S. Friedman and Patricia Keneally-Morrison are among my favorites (you will understand why my domain is named Keltia …). Recently, I’ve read novels from Anne Bishop, the writing is not so great but I like the story and characters; and the Vlad Thaltos novels from Steven Brust for fun. More recently, I’ve read novels from Lynn Flewelling (incl. The Bone Doll’s Twin and its following). Self-publishing is all the rage now, especially for ebooks and Lindsay Buroker is one of them, steam-punk kind of fantasy, I like her a lot.
My Goodreads profile with most of my books is there.
-
Cryptography has been of interest to me even before I owned my first computer (a ZX-81 if you want to know) back in 1980… My list of previously owned computers include an Oric Atmos, a Sinclair QL and various PCes.
-
Photography in case you haven’t noticed on the site before :)
-
Typography is also something I’m interested in, mostly French but also English as well. That includes fonts and how to write correctly.
-
I listen to music all the time. My favourite band is Dead Can Dance, closely followed by old songs from Deep Purple, Genesis, The Who, Pink Floyd, Jethro Tull and some Hard Rock/Metal like Metallica, Iron Maiden, Therion, Sabaton and Apocalyptica. I also like the music from Pat Benatar, Loreena McKennitt, Agnes Obel and many others. I’m also a big Count Basie and Miles Davis fan amongst many Jazz bands & singers.

Cats, I just love them.

** The first two are really preferred as I do manage the mail server behind these two, not GMail. Guess which one I trust more? :) **
PGP keys
NEW GPG Key! Please use only this one there or the ECC one (see below) from now on.
The old one below uses all the bad keysizes/algorithms that are referenced here. Check your own!

For testing purposes, I created a new key using the ed25519 Elliptic Curve using GPG 2.1.21. You need at least 2.1 to create ECC keys. While it is not yet an IETF standard it is expected to be soonish. These keys are smaller, probably faster to handle and hopefully more secure than RSA.

You can find a local copy here.
This key has not been signed except by myself but will be soon. It has been sent to Keybase as well.
My old-old-do-not-use-any-more GPG key is the following:
pub 1024D/7DCAE9D3 1997-08-21
uid Ollivier Robert <roberto@keltia.freenix.fr>
uid Ollivier Robert <roberto@keltia.net>
uid Ollivier Robert <roberto@FreeBSD.org>
sub 2048g/C267084D 1997-08-21
You can find it on the current PGP servers like pgp.mit.edu or here but I do not recommend you to use it. DSA/1024 keys are not really secure and flaws were discovered in the implementation of them so any old keys really ought to be regenerated.
Security stuff
You can also find stuff on Keybase, a new site aiming to do “crypto for the masses”.
