This perl module provides support for the HTTPS protocol under LWP, so that an LWP::UserAgent can make HTTPS GET & HEAD & POST requests. Please see perldoc LWP for more information on POST requests.

The Crypt::SSLeay package contains Net::SSL, which is automatically loaded by LWP::Protocol::https on HTTPS requests, and provides the necessary SSL glue for that module to work via these deprecated modules: Crypt::SSLeay::CTX, Crypt::SSLeay::Conn and Crypt::SSLeay::X509.
