digitalmars.D.learn - HTTPS, SSL, TLS client on D

I continue to practice with web applications on D and I have some 
questions about secure protocols of data transmissions. I don't 
have any experience with SSL/TLS so I need an advice how to get 
started. Is there any ready solution how to create client based 
on secured socket (for example HTTPS client). I would consider 
some existing C library with "good" interface. I was looking at 
libcurl but it looks confusing and couldn't make something that 
works.

P.S. I would be glad for any useful advice

If your goal is to write web applications in D, probably you 
should use a web-framework (like vibe.d) or a (fast/s)cgi 
interface over a well known server.

In our company we use D for web applications using fastcgi with 
nginx and lightppd. It works fine, also with https that is 
managed by nginx itself.

In this case I want client programme on D that will communicate
with some server over secure HTTP. I want to be able to update
DNS records via it's web API using web interface of my web
application written on D. I could do it using some cross-site
request on JavaScript XmlHTTPRequest, but I want to have some
console utility too. HTTPS client written on D would be suitable
but only obvious idea is to use libcurl. But it has slightly
complicated C interface. Is there something simplier exists that
you can advise?

Did you missed this?

You can also use OpenSSL. I wrote a little wrapper class that 
extends std.socket.Socket for it:

https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff/blob/master/sslsocket.d


If you download that file and compile it with your app:

dmd yourfile.d sslsocket.d

you should be able to

import sslsocket.

void main() {
         auto sock = new OpenSslSocket(AddressFamily.INET);
         sock.connect(new InternetAddress("localhost", 443));
         sock.send("GET / HTTP/1.0\r\n\r\n");
         import std.stdio;
         char[1024] buffer;
         writeln(buffer[0 .. sock.receive(buffer)]);
}



which gets from a local https server. Or of course you can 
connect to other things too and use the raw socket.


If you want a wrapper library to do http, curl is one option

phobos wrapper:
http://dlang.org/phobos/std_net_curl.html

my old wrapper:
https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff/blob/master/curl.d

the key function on mine is:

string curl(string url, string data = null, string contentType = 
"application/x-www-form-urlencoded");

if you pass it a data string, it does a POST, otherwise it goes a 
GET on the url.



I've also written non-curl http clients (see http.d and http2.d 
in my github), a http server (see cgi.d, it doesn't do ssl itself 
but you can put it behind apache or nginx or IIS to get it from 
them), and some oauth code (oauth.d in there). If you need to 
know anything about them feel free to ask.
