Face to Face: Committer’s Day

,

At the Face to Face meeting held on the occasion of the ICMC19 Conference in Vancouver, a novelty was introduced: For the last day of the meeting all committers were invited to participate, either personally or remotely via video conference.

OpenSSL 3.0 and FIPS Update

,

As mentioned in a previous blog post, OpenSSL team members met with various representatives of the FIPS sponsor organisations back in September last year to discuss design and planning for the new FIPS module development project.

Since then there has been much design work taking place and we are now able to publish the draft design documentation. You can read about how we see the longer term architecture of OpenSSL changing in the future here and you can read about our specific plans for OpenSSL 3.0 (our next release which will include a FIPS validated module) here.

Celebrating 20 Years of OpenSSL

,

20 years ago, on the 23rd December 1998, the first version of OpenSSL was released. OpenSSL was not the original name planned for the project but it was changed over just a few hours before the site went live. Let’s take a look at some of the early history of OpenSSL as some of the background has not been documented before.

The Holy Hand Grenade of Antioch

,

The OpenSSL Management Committee has been looking at the versioning scheme that is currently in use. Over the years we’ve received plenty of feedback about the “uniqueness” of this scheme, and it does cause some confusion for some users. We would like to adopt a more typical version numbering approach.

The current versioning scheme has this format:

MAJOR.MINOR.FIX[PATCH]

The new scheme will have this format:

MAJOR.MINOR.PATCH

In practical terms our “letter” patch releases become patch numbers and “fix” is dropped from the concept. In future, API/ABI compatibility will only be guaranteed for the same MAJOR version number. Previously we guaranteed API/ABI compatibility across the same MAJOR.MINOR combination. This more closely aligns with the expectations of users who are familiar with semantic versioning. We are not at this stage directly adopting semantic versioning because it would mean changing our current LTS policies and practices.

The current 1.1.1 and 1.0.2 versioning scheme will remain unchanged.

The current development version (master branch) will be identified as version 3.0.0. The OpenSSL FIPS module currently under development will also follow this versioning scheme. We are skipping the 2.0.0 major version because the previous OpenSSL FIPS module has already used this number.

OpenSSL version 3.0.0 will be the first version that we release under the Apache License 2.0. We will not be applying the Apache License to earlier releases of OpenSSL.

FIPS 140-2: Forward Progress

,

The OpenSSL Management Committee (OMC) on behalf of the OpenSSL Project would like to formally express its thanks to the following organisations for agreeing to sponsor the next FIPS validation effort: Akamai Technologies, Blue Cedar, NetApp, Oracle, VMware.

Four weeks ago, the OpenSSL team gathered with many of the organisations sponsoring the next FIPS module for a face-to-face meeting in Brisbane, Australia.

We got a great deal accomplished during that week. Having most of the fips-sponsor organisations in the same location helps ensure that we are all on the same page for the decisions we need to make going forward.

OpenSSL 1.1.1 Is Released

,

After two years of work we are excited to be releasing our latest version today - OpenSSL 1.1.1. This is also our new Long Term Support (LTS) version and so we are committing to support it for at least five years.

OpenSSL 1.1.1 has been a huge team effort with nearly 5000 commits having been made from over 200 individual contributors since the release of OpenSSL 1.1.0. These statistics just illustrate the amazing vitality and diversity of the OpenSSL community. The contributions didn’t just come in the form of commits though. There has been a great deal of interest in this new version so thanks needs to be extended to the large number of users who have downloaded the beta releases to test them out and report bugs.

New LTS Release

,

Back around the end of 2014 we posted our release strategy. This was the first time we defined support timelines for our releases, and added the concept of an LTS (long-term support) release. At our OMC meeting earlier this month, we picked our next LTS release. This post walks through that announcement, and tries to explain all the implications of it.
