What module is needed to allow scripts to post to HTTPS sites?

[petesouthwest@hotmail.com]

Hi

I have been told that in order for my Perl script to be able to post
to an https address, there needs to be an extra library/object
installed on my server, like CURL for php. Can anyone tell me the name
of the library? Is there just one or are there alternatives?

Many thanks

Pete

I think my host is using CPAN Perl?

CPAN: Crypt::SSLeay.

Maybe Net::SSLeay would work equally; haven't tried.

No expert on this - but I think there are alternatives.

LWP::UserAgent has both a 'get' and 'post' method. Here's a simple script
that does a https 'get':

use warnings;
use strict;
use LWP::UserAgent;

my $url = 'https://www.thawte.com';

my $ua = new LWP::UserAgent;

my $req = new HTTP::Request('GET', $url);

my $res = $ua->request($req);

if ($res->is_success) {print $res->as_string}

else {print "Failed: ", $res->status_line, "\n"}

__END__

On my box that works because I have both IO::Socket::SSL and Net::SSLeay
installed. (The latter is needed by the former.)
If I rename either one of those modules (so that it cannot be found) the
script fails with the message:

Failed: 501 Protocol scheme 'https' is not supported (Crypt::SSLeay not
installed)

From that I deduce that Crypt::SSLeay is an alternative to the
IO::Socket::SSL/Net::SSLeay combination. Crypt::SSLeay has not been updated
in over 4 years ... so I'm a little wary (perhaps without justification) of
it.

There are probably other alternatives to LWP::UserAgent - eg WWW::Mechanize.
I would think that they too utilize IO::Socket::SSL/Net::SSLeay and/or
Crypt::SSLeay ... but I haven't checked.

Cheers,

See also IO::All. From the documentation of IO::All::HTTPS
"Note that in most cases it is simpler just to call
io('https://example.com'), which calls the https method automatically.
[...] The same operators from IO::All may be used. < GETs an HTTPS URL;

> PUTs to an HTTPS URL."

Thats great thank you all. I'm not up on Perl or webservers, so this
helps a lot. My Host has said to offer SSL I would need to upgrade to a
dedicated server :( at over £100
a month.

Is installing something like Crypt::SSLeay difficult? Any ideas why I
should need to upgrade to a dedicated server in order to get SSL
support?

Can I just clarify how this relates to having an SSL cert? When i have
asked this question to other poeple they have started talking about
secure sites. but isnt that different from support for the SSL
protocol?

Many thanks
Pete

That of course is completely unrelated to your original question, which
was about accessing a site, not serving a site.

> Is installing something like Crypt::SSLeay difficult?

Usually not; YMMV.

They're using it as an excuse to make more money? :-)

Your problem appears to be clarifying what it is that you want, because I
cannot tell why you are talking about posting to an https address at the
same time as serving a secure site. Unless what you mean by 'post' is
different from the usual interpretation of an HTTP request. What *do* you
mean by 'post'?

Crypt::SSLeay is maintained to enable https requests wia libwww (LWP)
so install that if you use LWP

Net::SSLeay is the way to go for new code.

both depend on openssl. see [url]www.openssl.org[/url] to install it.

if you want to use the curl perl modules(like WWW::Curl::Easy), you'll
need libcurl with
openssl support

overall highly OS-dependent as you need to build C libraries
the openssl build process has become worse lately on some platforms
as libopenssl has been split in two (one has become a dependency of the
other and tries to load ./libXXX instead of the full path)
if your platform uses /usr/local or /usr/lib only everything is OK.
