It ships libcrypto, libssl, libtls, and command-line utilities such as openssl and ocspcheck. ### Project history The official site describes LibreSSL as forked from OpenSSL in 2014, with primary development inside the OpenBSD source tree and regular portable repackaging for other operating systems. The portable repository states the fork point as OpenSSL 1.0.1g and explains that the GitHub project contains the build scaffold and compatibility layer for building OpenBSD's LibreSSL code outside OpenBSD. The project goals are deliberately conservative: modernize the OpenSSL codebase, apply code review and frequent releases, remove obsolete or broken features and operating-system support, and encourage safer programming interfaces. The portable README also makes clear that LibreSSL is not ABI-compatible with OpenSSL and that API compatibility is limited by the projects' different priorities. ### Adoption history LibreSSL was adopted first as part of OpenBSD and then as a portable package for Linux, BSDs, macOS, Windows, and other systems. Its wider package-manager life has been shaped by a trade-off: users wanted a cleaned-up OpenSSL-compatible stack, but many large ecosystems remained tied to OpenSSL ABI/API expectations. For Unix distributions and Homebrew, LibreSSL became a useful alternate TLS implementation and a source of the libtls API, while also serving as a practical stress test for software that claimed OpenSSL portability but depended on OpenSSL-specific behavior. ### How it is used Packaged LibreSSL is used either by linking applications to libcrypto, libssl, or libtls, or through command-line tools such as openssl and ocspcheck. The release process tracks OpenBSD development: stable portable branches are derived from OpenBSD releases and receive security updates for a defined support window. ### Why package nerds care LibreSSL is package-nerd significant because it is a security fork with real downstream consequences. It forces maintainers to separate OpenSSL-the-API from OpenSSL-the-implementation, exposes accidental ABI assumptions, and gives package managers a second TLS stack whose release cadence is tied to OpenBSD rather than the OpenSSL project. ### Timeline - 2014: LibreSSL forked from OpenSSL. - 2014-07-11: LibreSSL 2.0.0 released, based on an OpenBSD 5.6 development snapshot. - 2014-08-08: LibreSSL 2.0.5 tied to OpenBSD 5.6 release. - 2015-09-23: LibreSSL 2.3.0 released. - 2024-10-14: LibreSSL 4.0.0 released. - 2026-05-25: LibreSSL 4.3.2 released. ### Related projects - Related projects include OpenSSL, OpenBSD's libcrypto/libssl/libtls trees, BoringSSL, AWS-LC, wolfSSL, mbedTLS, and downstream software such as OpenSSH and curl that depend on TLS libraries. ### Sources - - - - ## Security Notes library-like package without higher-risk signals. - **Geiger risk:** green / low - library-like package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
