Aleš Mareček

SysOps and DevOps Engineer, Security enthusiast, Quality driven, Bug hunter, Open source ambassador. To be honest and responsible are one of the core values I keep. I believe that meritocracy and transparency are inseparable parts from the way to build a successful community. I’m into security since 1998 when my personal OpenBSD server and firewall started playing zeroes and ones games on Internet. At that time I met OpenSSL for the first time. During a couple of years I was using and testing OpenSSL libraries in both work and personal lives. Finally I joined OpenSSL in 2022 to become a part of the project as Sys/DevOps.

Anton Arapov

Joining the OpenSSL team in February 2023, I brought along experience from previous roles in Red Hat and Mavenir. At Red Hat, I had the opportunity to grow from an engineer to an engineering manager, contributing to the Linux Kernel and later leading teams in OpenStack and OpenShift projects. My journey then led me to Mavenir, where I applied my skills and knowledge to help align the company’s telecom products and services with the realities of a modern cloud environment. Now at OpenSSL, I am committed to utilizing my experience to contribute to our shared mission of enhancing digital security through reliable encryption solutions.

Hugo Landau

I’m a software and infrastructure engineer with a background in networking, security and cryptography. An OTC member, I take principal responsibility for the development of OpenSSL’s QUIC functionality. As a strong believer in the values of open source, I’m proud to be part of the OpenSSL project given its instrumental role in the security of internet infrastructure.

Mark J Cox

I am proud to have been one of the original founders of the OpenSSL project back in 1998. Throughout the years, I have contributed my expertise in security vulnerability handling, management, and finance. Presently, my primary focus is on the financial aspects, working to ensure the project’s long-term sustainability and success.

Matt Caswell

I have been a full time developer on the OpenSSL Project since 2014 with a particular focus on libssl. I have been lucky to be involved with the development of major features in OpenSSL over the years including the implementation of TLSv1.3, the new provider architecture in 3.0, the new FIPS module and QUIC. As well as development I am also active in the governance of OpenSSL including as a member of OpenSSL’s management and technical committees.

Paul Dale

I worked sporadically with OpenSSL on embedded systems from the early 2000s and started contributing back to the project in 2016, finally joining the team full time in 2021 to concentrate on making OpenSSL better than ever. I have a special interest in entropy and randomness and am a member of the management and technical committees.

Richard Levitte

I’ve been an active FOSS contributor since 1990, with a focus on the operating system OpenVMS at the time. Back then, I mainly ported diverse GNU programs (most of all newer versions of Emacs) to that operating system. In the late 1990’s, I became interested in cryptography, which led me to SSLeay, and then to the OpenSSL Project, which I became an active member of in late 1999. This has been my most consistent FOSS activity ever since.

Tam Dale

I joined the project in July 2023, and as the only non-technical contractor, there’s been quite a learning curve. My role is to manage our support contracts, assist our Customers and Sponsors, manage the day to day operational side of the Project, as well as to develop procedures and policies that support the Project’s long term goals.

Tim Hudson

Co-founded SSLeay in 1996, worked on RSA’s “forks” from 1998-2007, joined old-OSF for OpenSSL commercial activities in 2008-2014, officially joined the “OpenSSL Project” as a volunteer in 2014. Member of the OMC, OTC, and a committer. Focused on governance, long term sustainability, business relationships, practical application of security technologies for the project.

Tomáš Mráz

I developed and maintained various security and crypto-related software at Red Hat since 2004. Among other duties including maintaining the OpenSSL package I worked to ensure that the crypto libraries incorporated into Red Hat Enterprise Linux were FIPS compliant and validated. After leaving Red Hat in 2021, I was happy to join the OpenSSL project, where I helped finalize the OpenSSL 3.0 release and get the FIPS provider module validated. Currently, my primary focus is developing the implementation of the QUIC protocol in OpenSSL and making sure we respond to issues raised on our github project in a timely manner.
