libio-socket-ssl-perl 2.060-3~ubuntu18.04.1 (amd64 binary) in ubuntu bionic

 This module is a true drop-in replacement for IO::Socket::INET that
 uses SSL to encrypt data before it is transferred to a remote server
 or client. IO::Socket::SSL supports all the extra features that one
 needs to write a full-featured SSL client or server application:
 multiple SSL contexts, cipher selection, certificate verification, and
 SSL version selection. As an extra bonus, it works perfectly with
 mod_perl.
 .
 IO::Socket::SSL uses IPv6 if libio-socket-ip-perl (>= 0.20) or
 libio-socket-inet6-perl is installed.
