Have you heard of Google? Super Search? Have you ever bought anything on line? HTTPS is the secure version of HTTP (the ubiquitous Hyper Text Transport Protocol you are using right now to read this page). HTTPS uses SSL (Secure Sockets Layer) to allow secure(ish) connections. I suggest you have a look at (as a start):

• IO::Socket::SSL
• Crypt::SSLeay
• http://www.openssl.org/

To answer you question the likely answer is yes you need more modules, probably libraries like openssl to generate your certificates and more research.
