Could you tell a bit more about your problem? What have you tried already? What do you mean by HTTPS with both sides exchanging credentials? Do you mean SSL authentication or what? Have a look onto IO::Socket::SSL.

Update: oh, I missed LWP in subject. You should install Crypt::SSLeay in order to enable TLS support in LWP.

Here's what I tried:


use warnings;
use strict;
use LWP;
use HTTP::Message;
# For TLS connection
use LWP::Protocol::https;
use Crypt::SSLeay;

# TLS stuff
$ENV{HTTPS_DEBUG}   = 1;
$ENV{HTTPS_VERSION} = 3;
$ENV{'HTTPS_CERT_FILE'} = '/opt/CT/certs/EHR_ICA.ihe.net.pem';
$ENV{'HTTPS_KEY_FILE'}  = '/opt/CT/requests/EHR_ICA.ihe.net.pem';

my $req = HTTP::Request->new(POST => $self->{'endpoint'});
# ...

I installed the certificate and passkey files, but when I run my script, here is what I get:


$ perl -w xds_qry.pl
Enter PEM pass phrase:
SSL_connect:before/connect initialization
SSL_connect:SSLv3 write client hello A
SSL_connect:failed in SSLv3 read server hello A
Enter PEM pass phrase:
SSL_connect:before/connect initialization
SSL_connect:SSLv2 write client hello A
SSL_connect:failed in SSLv2 read server hello A

syntax error at line 1, column 0, byte 0:
500 SSL negotiation failed:

It seems strange to me that the passkey prompt comes up in the first place. I tried a few options, but they didn't work.

There's no need in

# For TLS connection
use LWP::Protocol::https;
use Crypt::SSLeay;

LWP should use them automatically. Also $ENV{HTTPS_VERSION} = 3 should allow only SSLv3, try $ENV{HTTPS_VERSION} = 23 if you want TLS.
