This package is the official portable version of LibreSSL
(http://www.libressl.org).
LibreSSL is a fork of OpenSSL developed by the OpenBSD project
(http://www.openbsd.org). LibreSSL is developed on OpenBSD. This
package then adds portability shims for other operating systems.
LibreSSL is a fork of OpenSSL 1.0.1 developed by the OpenBSD project.
(http://www.openbsd.org).
Compatibility with OpenSSL:
LibreSSL is API compatible with OpenSSL 1.0.1, but does not yet include all
new APIs from OpenSSL 1.0.2 and later. LibreSSL also includes APIs not yet
present in OpenSSL. The current common API subset is OpenSSL 1.0.1.
LibreSSL it is not ABI compatible with any release of OpenSSL, or necessarily
earlier releases of LibreSSL. You will need to relink your programs to
LibreSSL in order to use it, just as in moving between major versions of OpenSSL.
LibreSSL's installed library version numbers are incremented to account for
ABI and API changes.
Compatibility with other operating systems:
While primarily developed on and taking advantage of APIs available on OpenBSD,
the LibreSSL portable project attempts to provide working alternatives for
other operating systems, and assists with improving OS-native implementations
where possible.
At the time of this writing, LibreSSL is know to build and work on:
- Linux (kernel 3.17 or later recommended)
- FreeBSD (tested with 9.2 and later)
- NetBSD (tested with 6.1.5)
- HP-UX (11i)
- Solaris (11 and later preferred)
- Mac OS X (tested with 10.8 and later)
- AIX (5.3 and later)
LibreSSL also supports the following Windows environments:
- Microsoft Windows (Vista or higher, x86 and x64)
- Wine (32-bit and 64-bit)
- Builds with Mingw-w64 and Cygwin
Official release tarballs are available at your friendly neighborhood

or run './dist.sh' to prepare a tarball.
Once you have a source tree from Git or FTP, run these commands to build and
install the package:
install the package on most systems.
./configure # see ./configure --help for configuration options
make check # runs builtin unit tests
make install # set DESTDIR= to install to an alternate location
The resulting library and 'openssl' utility is largely API-compatible with
OpenSSL 1.0.1. However, it is not ABI compatible - you will need to relink your
programs to LibreSSL in order to use it, just as in moving from OpenSSL 0.9.8
to 1.0.1.
The project attempts to provide working alternatives for operating systems with
limited or broken security primitives (e.g. arc4random(3)) and assists with
improving OS-native implementations where possible.
LibreSSL portable will build on any reasonably modern version of Linux,
Solaris, or OSX with a standards-compliant compiler and C library.
