stunnel 5.14

The stunnel program works as SSL encryption wrapper between remote and local network sockets or inetd-started daemons. It adds SSL or TLS functionality to any network service, commonly POP3, IMAP or HTTP servers. Stunnel uses OpenSSL for cryptography. It can itself function as port redirection deamon, or as temporary traffic interceptor, and requires no adaption of the shadowed programs.

LibreSSL 2.1.6

LibreSSL Portable is a free version of the SSL/TLS protocol forked from OpenSSL, and developed by the OpenBSD project. LibreSSL is developed as part of the OpenBSD system, with lots of ancient cruft and security woes already fixed. The portable version for other Unices is developed alongside.
