\&\f(CW\*(C`perl Makefile.PL\*(C'\fR will display a warning if it thinks your OpenSSL might be vulnerable to the  Heartbleed Bug <https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0160>. You can, of course, go ahead and install the module, but you should be aware that your system might be exposed to an extremely serious vulnerability. This is just a heuristic based on the version reported by OpenSSL. It is entirely possible that your distrbution actually pushed a patched library, so if you have concerns, you should investigate further.

This Perl module provides support for the \s-1HTTPS\s0 protocol under \s-1LWP\s0, to
allow an LWP::UserAgent object to perform \s-1GET, HEAD,\s0 and \s-1POST\s0 requests
over encrypted socket connections. Please see \s-1LWP\s0 for more information
on \s-1POST\s0 requests.
.PP
The \f(CW\*(C`Crypt::SSLeay\*(C'\fR package provides \f(CW\*(C`Net::SSL\*(C'\fR, which, if requested, is
loaded by \f(CW\*(C`LWP::Protocol::https\*(C'\fR for https requests and provides the
necessary \s-1SSL\s0 glue.

.SH "DO YOU NEED Crypt::SSLeay?"
.IX Header "DO YOU NEED Crypt::SSLeay?"
Starting with version 6.02 of \s-1LWP\s0, \f(CW\*(C`https\*(C'\fR support was unbundled into
LWP::Protocol::https. This module specifies as one of its prerequisites
IO::Socket::SSL which is automatically used by LWP::UserAgent unless
this preference is overridden separately. \f(CW\*(C`IO::Socket::SSL\*(C'\fR is a more
complete implementation, and, crucially, it allows hostname verification.
\&\f(CW\*(C`Crypt::SSLeay\*(C'\fR does not support this. At this point, \f(CW\*(C`Crypt::SSLeay\*(C'\fR is
maintained to support existing software that already depends on it.
However, it is possible that your software does not really depend on
\&\f(CW\*(C`Crypt::SSLeay\*(C'\fR, only on the ability of \f(CW\*(C`LWP::UserAgent\*(C'\fR class to
communicate with sites over \s-1SSL/TLS.\s0
.PP
If are using version \f(CW\*(C`LWP\*(C'\fR 6.02 or later, and therefore have installed
\&\f(CW\*(C`LWP::Protocol::https\*(C'\fR and its dependencies, and do not explicitly \f(CW\*(C`use\*(C'\fR
\&\f(CW\*(C`Net::SSL\*(C'\fR before loading \f(CW\*(C`LWP::UserAgent\*(C'\fR, or override the default socket
class, you are probably using \f(CW\*(C`IO::Socket::SSL\*(C'\fR and do not really need
\&\f(CW\*(C`Crypt::SSLeay\*(C'\fR.
.PP
If you have both \f(CW\*(C`Crypt::SSLeay\*(C'\fR and \f(CW\*(C`IO::Socket::SSL\*(C'\fR installed, and
would like to force \f(CW\*(C`LWP::UserAgent\*(C'\fR to use \f(CW\*(C`Crypt::SSLeay\*(C'\fR, you can

If everything builds \s-1OK,\s0 but you get failures when during tests, ensure that
\&\f(CW\*(C`LD_LIBRARY_PATH\*(C'\fR points to the location where the correct shared libraries
are located.
.PP
If you are using a custom OpenSSL build, please keep in mind that
\&\f(CW\*(C`Crypt::SSLeay\*(C'\fR must be built using the same compiler and build tools used
to build \f(CW\*(C`perl\*(C'\fR and OpenSSL. This can be more of an issue on Windows. If
you are using Active State Perl, install the MinGW package distributed by
them, and build OpenSSL using that before trying to build this module. If
you have built your own Perl using Microsoft \s-1SDK\s0 tools or IDEs, make sure
you build OpenSSL using the same tools.
.PP
Depending on your \s-1OS,\s0 pre-built OpenSSL packages may be available. To get
the require headers and import libraries, you may need to install a
development version of your operating system's OpenSSL library package. The
key is that \f(CW\*(C`Crypt::SSLeay\*(C'\fR makes calls to the OpenSSL library, and how to
do so is specified in the C header files that come with the library. Some
systems break out the header files into a separate package from that of the
libraries. Once the program has been built, you don't need the headers any
more.
.SS "Crypt::SSLeay"
.IX Subsection "Crypt::SSLeay"
The latest Crypt::SSLeay can be found at your nearest \s-1CPAN\s0 mirror, as well
as <https://metacpan.org/pod/Crypt::SSLeay>.

Once you have downloaded it, \f(CW\*(C`Crypt::SSLeay\*(C'\fR installs easily using the
standard build process:

If you would like to use \f(CW\*(C`cpanm\*(C'\fR with such custom locations, you can do
.PP

If you are on Windows, and using a MinGW distribution bundled with
ActiveState Perl or Strawberry Perl, you would use \f(CW\*(C`dmake\*(C'\fR rather than
\&\f(CW\*(C`make\*(C'\fR. If you are using Microsoft's build tools, you would use \f(CW\*(C`nmake\*(C'\fR.

For unattended (batch) installations, to be absolutely certain that

.SH "PROXY SUPPORT"
.IX Header "PROXY SUPPORT"
LWP::UserAgent and Crypt::SSLeay have their own versions of
proxy support. Please read these sections to see which one
is appropriate.
.SS "LWP::UserAgent proxy support"
.IX Subsection "LWP::UserAgent proxy support"
\&\f(CW\*(C`LWP::UserAgent\*(C'\fR has its own methods of proxying which may work for you
and is likely to be incompatible with \f(CW\*(C`Crypt::SSLeay\*(C'\fR proxy support.
To use \f(CW\*(C`LWP::UserAgent\*(C'\fR proxy support, try something like:
.PP
.Vb 2
\&    my $ua = LWP::UserAgent\->new;
\&    $ua\->proxy([qw( https http )], "$proxy_ip:$proxy_port");
.Ve
.PP
At the time of this writing, libwww v5.6 seems to proxy https requests
fine with an Apache \fImod_proxy\fR server.  It sends a line like:
.PP
.Vb 1
\&    GET https://www.example.com HTTP/1.1
.Ve
.PP
to the proxy server, which is not the \f(CW\*(C`CONNECT\*(C'\fR request that some
proxies would expect, so this may not work with other proxy servers than
\&\fImod_proxy\fR. The \f(CW\*(C`CONNECT\*(C'\fR method is used by \f(CW\*(C`Crypt::SSLeay\*(C'\fR's
internal proxy support.
.SS "Crypt::SSLeay proxy support"
.IX Subsection "Crypt::SSLeay proxy support"
For native \f(CW\*(C`Crypt::SSLeay\*(C'\fR proxy support of https requests,
you need to set the environment variable \f(CW\*(C`HTTPS_PROXY\*(C'\fR to your
proxy server and port, as in:
.PP
.Vb 3
\&    # proxy support
\&    $ENV{HTTPS_PROXY} = \*(Aqhttp://proxy_hostname_or_ip:port\*(Aq;
\&    $ENV{HTTPS_PROXY} = \*(Aq127.0.0.1:8080\*(Aq;
.Ve
.PP
Use of the \f(CW\*(C`HTTPS_PROXY\*(C'\fR environment variable in this way
is similar to \f(CW\*(C`LWP::UserAgent\-\*(C'\fR\fIenv_proxy()\fR> usage, but calling
that method will likely override or break the \f(CW\*(C`Crypt::SSLeay\*(C'\fR
support, so do not mix the two.
.PP
Basic auth credentials to the proxy server can be provided
this way:
.PP
.Vb 3
\&    # proxy_basic_auth
\&    $ENV{HTTPS_PROXY_USERNAME} = \*(Aqusername\*(Aq;
\&    $ENV{HTTPS_PROXY_PASSWORD} = \*(Aqpassword\*(Aq;
