I am writing a SSL enabled HTTP client but am having problems getting the SSL layer to initialize before writing to the socket. To create the tcp socket I am using IO::Socket::INET.

Any examples i've seen use Socket to create and associate the file descriptor to the SSL layer. Is there any way I can associate the file descriptor from the IO::Socket::INET object to the SSL layer? My code below only produces the output of: Cipher `(NONE)' 

#!/usr/local/bin/perl
use IO::Socket::INET;
use Net::SSLeay qw(die_now die_if_ssl_error ssl_read_all print_errs) ;
Net::SSLeay::load_error_strings();
Net::SSLeay::SSLeay_add_ssl_algorithms();
Net::SSLeay::randomize();
$|++;

($dest_serv, $port, $msg) = @ARGV;      # Read command line
my $sock = IO::Socket::INET->new(    Proto        => 'tcp',
                                    Type        => SOCK_STREAM,
                                    Blocking    => 0 );
$sock->connect( $port, inet_aton($dest_serv) );

$ctx = Net::SSLeay::CTX_new() or die_now("Failed to create SSL_CTX $!"
+);
Net::SSLeay::CTX_set_options($ctx, &Net::SSLeay::OP_ALL)
    and die_if_ssl_error("ssl ctx set options");
$ssl = Net::SSLeay::new($ctx) or die_now("Failed to create SSL $!");
Net::SSLeay::set_fd($ssl, fileno($sock));
$res = Net::SSLeay::connect($ssl) and die_if_ssl_error("ssl connect");
print "Cipher `" . Net::SSLeay::get_cipher($ssl) . "'\n";

$res = Net::SSLeay::write($ssl, "GET / HTTP/1.1\nHOST: $dest_serv\n\n"
+);
die_if_ssl_error("ssl write");
CORE::shutdown $sock, 1;

$got = Net::SSLeay::ssl_read_all($ssl);
die_if_ssl_error("ssl read");
Net::SSLeay::free ($ssl);
Net::SSLeay::CTX_free ($ctx);
close $sock;

print $got;
