NAME

    Alien::LibreSSL - Alien wrapper for LibreSSL (alternative to OpenSSL)

VERSION

    version 0.03

SYNOPSIS

    EUMM:

     use ExtUtils::MakeMaker;
     use Alien::Base::Wrapper qw( Alien::LibreSSL !export );
     
     WriteMakefile(
       ...
       CONFIGURE => {
         'Alien::Build::Wrapper' => 0,
         'Alien::LibreSSL'       => 0,
       },
       Alien::Base::Wrapper->mm_args,
     );

    MB:

     use Module::Build;
     use Alien::Base::Wrapper qw( Alien::LibreSSL !export );
     
     my $build = Module::Build->new(
       ...
       configure_requires => {
         'Alien::Build::Wrapper' => 0,
         'Alien::LibreSSL'       => 0,
       },
       Alien::Base::Wrapper->mb_args,
       ...
     );
     
     $build->create_build_script;

    Perl script:

     use Alien::LibreSSL;
     use Env qw( @PATH );
     
     unshift @PATH, 'Alien::LibreSSL->bin_dir;
     system 'openssl ...';

DESCRIPTION

    This module provides an implementation of SSL. It will use the system
    SSL, if it can be found. If the system does not provide SSL, this alien
    will download and build LibreSSL, a drop in replacement for OpenSSL

 Motivation

    SSL has lots of pitfalls. SSL on Perl has all of those pitfalls plus
    some more. Once you get Net::SSLeay you are mostly out of the woods.
    Getting Net::SSLeay to install can be problematic on some platforms. My
    hope is that some combination of this module and Alien::OpenSSL will
    one day make it easier to install Net::SSLeay.

CAVEATS

    Normally Alien::Build + alienfile use Net::SSLeay (via HTTP::Tiny or
    LWP::UserAgent) in order to download https URLs from the internet, but
    for this to be a dependency of Net::SSLeay that will obviously not
    work. Instead this alien attempts to bootstrap SSL by downloading via
    wget or curl, if they are available. By default, if they are not
    available then this Alien will attempt to download via http. This
    obviously might not be desirable for some so you can set
    ALIEN_OPENSSL_FTP to 0 if you want to ensure the transfer happens over
    https (and will die, if it isn't available).

ENVIRONMENT

    ALIEN_OPENSSL_FTP

      Set to 1 to allow downloads via ftp or http (the default). Set to 0
      to disallow insecure downloads over ftp or http.
