Binary package “stunnel4” in ubuntu precise

Universal SSL tunnel for network daemons

 The stunnel program is designed to work as SSL encryption
 wrapper between remote client and local (inetd-startable) or
 remote server. The concept is that having non-SSL aware daemons
 running on your system you can easily setup them to
 communicate with clients over secure SSL channel.
 stunnel can be used to add SSL functionality to commonly
 used inetd daemons like POP-2, POP-3 and IMAP servers
 without any changes in the programs' code.
 This package contains a wrapper script for compatibility with stunnel 3.x
