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. 

Official release tarballs are available at your friendly neighborhood
OpenBSD mirror in directory LibreSSL, e.g.:
http://ftp.openbsd.org/pub/OpenBSD/LibreSSL/
although it is suggested you use a mirror. 

Development is done in the upstream OpenBSD codebase.  A github clone
of the official repositories is kept at:
https://github.com/libressl-portable
We update this repository from the OpenBSD respositories
semi-frequently, so changes may not show up in GitHub immediately. 
The GitHub repository should be used for informational purposes
only.

./configure && make check && make install

See crypto/compat for the bulk of the local compatibility code. 

It will likely build on any reasonably modern version of Linux, Solaris,
or OSX with a sane compiler and C library.

Note: Our policy is generally to use your system provided intrinsics.
If your system provides security sensitive functions (such as
arc4random(), issetugid(), calloc(), getentropy(), and others) we will
assume they are implemented correctly and securely. If they are
not please contact your OS provider.
