OpenSSL 3.0 appeared – Computer


OpenSSL version 3.0 was released after three years of development. The development team has made some changes to the popular SSL and TLS toolkit. It is therefore not fully compatible with previous versions.

OpenSSL 3.0.0 was preceded by seventeen alpha releases and two beta releases, over 7,500 engagements and contributions from over 350 developers, Mildt Matt Caswell of the OpenSSL Project. Compared to the previous version, OpenSSL 1.1.1, released in 2018, the available documentation has increased by 94% and the amount of code by 54%, he says.

One change is that OpenSSL is now covered by the Apache v2 license instead of its own OpenSSL or SSLeay license. What is new is the concept of “provider”, where users can select which provider they want to use for applications and these providers provide implementations of algorithms such as cipher modules. By default, there are five providers, one of which meets the US government FIPS standard or federal information handling standards. Third parties may also provide service providers that can connect to OpenSSL.

The OpenSSL team reports complete changes to the file. All changes made. Because this is a major release, applications running an earlier version of OpenSSL must be recompiled. Additionally, warnings about broken APIs may be displayed. The majority of applications that worked with OpenSSL 1.1.1 without modification should work with version 3.0.0 anyway, although modifications may be necessary in some cases, according to the OpenSSL project.

It was originally planned to release OpenSSL in 2019, but the release has been postponed more than once.
