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.
work on crypt::ssleay has been continued only to provide https support for the lwp - libwww perl libraries. if you want access to the openssl api via perl, check out sampo's net::ssleay (available in debian as the libnet-ssleay-perl package).
