SYNOPSIS
            # CLIENT-side usage

ABSTRACT
            Makes SSL use in POE a breeze!

DESCRIPTION
    This component represents the standard way to do SSL in POE.

NOTES
  Socket methods doesn't work
    The new socket this module gives you actually is some tied socket magic,
    so you cannot do stuff like getpeername() or getsockname(). The only way
    to do it is to use SSLify_GetSocket and then operate on the socket it
    returns.

  Dying everywhere...
    This module will die() if Net::SSLeay could not be loaded or it is not
    the version we want. So, it is recommended that you check for errors and
    not use SSL, like so:

            eval { use POE::Component::SSLify };
            if ( $@ ) {
                    $sslavailable = 0;
            } else {
                    $sslavailable = 1;
            }

            # Make socket SSL!
            if ( $sslavailable ) {
                    eval { $socket = POE::Component::SSLify::Client_SSLify( $socket ) };
                    if ( $@ ) {
                            # Unable to SSLify the socket...
                    }
            }

  OpenSSL functions
    Theoretically you can do anything that Net::SSLeay exports from the
    OpenSSL libs on the socket. However, I have not tested every possible
    function against SSLify, so use them carefully! If you have success,
    please report back to me so I can update this doc!

   Net::SSLeay::renegotiate
    This function has been tested ( it's in t/simple.t ) but it doesn't work
    on FreeBSD! I tracked it down to this security advisory:
    <http://security.freebsd.org/advisories/FreeBSD-SA-09:15.ssl.asc> which
    explains it in detail. The test will skip this function if it detects
    that you're on a FreeBSD system. However, if you have the updated
    OpenSSL library that fixes this you can use it.

FUNCTIONS
  Client_SSLify
            Accepts a socket, returns a brand new socket SSLified. Optionally accepts SSL
            context data.
                    my $socket = shift;                                             # get the socket from somewhere
                    $socket = Client_SSLify( $socket );                             # the default
                    $socket = Client_SSLify( $socket, $version, $options );         # sets more options for the context
                    $socket = Client_SSLify( $socket, undef, undef, $ctx );         # pass in a custom context

            If $ctx is defined, SSLify will ignore other args. If $ctx isn't defined, SSLify
            will create it from the $version + $options parameters.

            Known versions:
                    * sslv2
                    * sslv3
                    * tlsv1
                    * default

            By default we use the version: default

            By default we don't set any options

            NOTE: The way to have a client socket with proper certificates set up is:
                    my $socket = shift;     # get the socket from somewhere
                    my $ctx = SSLify_ContextCreate( 'server.key', 'server.crt' );
                    $socket = Client_SSLify( $socket, undef, undef, $ctx );

            BEWARE: If you passed in a CTX, SSLify will do Net::SSLeay::CTX_free( $ctx ) when the
            socket is destroyed. This means you cannot reuse contexts!

  Server_SSLify
            Accepts a socket, returns a brand new socket SSLified
                    my $socket = shift;     # get the socket from somewhere
                    $socket = Server_SSLify( $socket );

            NOTE: SSLify_Options must be set first!

            Furthermore, you can pass in your own $ctx object if you desire. This allows you to set custom parameters
            per-connection, for example.
                    my $socket = shift;     # get the socket from somewhere
                    my $ctx = Net::SSLeay::CTX_new();
                    # set various options on $ctx as desired
                    $socket = Server_SSLify( $socket, $ctx );

            NOTE: You can use SSLify_GetCTX to modify the global, and avoid doing this on every connection if the
            options are the same...

  SSLify_Options
            Accepts the location of the SSL key + certificate files and does it's job

            Optionally accepts the SSL version + CTX options
                    SSLify_Options( $key, $cert, $version, $options );

            Known versions:
                    * sslv2
                    * sslv3
                    * tlsv1
                    * default

            By default we use the version: default

            By default we use the options: &Net::SSLeay::OP_ALL

  SSLify_GetCTX
            Returns the server-side CTX in case you wanted to play around with it :)

            If passed in a socket, it will return that socket's $ctx instead of the global.
                    my $ctx = SSLify_GetCTX();                      # get the one set via SSLify_Options
                    my $ctx = SSLify_GetCTX( $sslified_sock );      # get the one in the object

  SSLify_GetCipher
            Returns the cipher used by the SSLified socket

            Example:
                    print "SSL Cipher is: " . SSLify_GetCipher( $sslified_sock ) . "\n";

            NOTE: Doing this immediately after Client_SSLify or Server_SSLify will result in "(NONE)" because the SSL handshake
            is not done yet. The socket is nonblocking, so you will have to wait a little bit for it to get ready.

  SSLify_GetSocket
            Returns the actual socket used by the SSLified socket, useful for stuff like getpeername()/getsockname()

            Example:
                    print "Remote IP is: " . inet_ntoa( ( unpack_sockaddr_in( getpeername( SSLify_GetSocket( $sslified_sock ) ) ) )[1] ) . "\n";

  SSLify_ContextCreate
            Accepts some options, and returns a brand-new SSL context object ( $ctx )
                    my $ctx = SSLify_ContextCreate();
                    my $ctx = SSLify_ContextCreate( $key, $cert );
                    my $ctx = SSLify_ContextCreate( $key, $cert, $version, $options );

            Known versions:
                    * sslv2
                    * sslv3
                    * tlsv1
                    * default

            By default we use the version: default

            By default we don't set any options

            By default we don't use the SSL key + certificate files

EXPORT
            Stuffs all of the above functions in @EXPORT_OK so you have to request them directly

            Original code is entirely Rocco Caputo ( Creator of POE ) -> I simply
            packaged up the code into something everyone could use and accepted the burden
            of maintaining it :)

            From the PoCo::Client::HTTP code =]
            # TODO - This code should probably become a POE::Kernel method,
            # seeing as it's rather baroque and potentially useful in a number
            # of places.

    ASCENT also helped a lot with the nonblocking mode, without his hard
    work this module would still be stuck in the stone age :)
