The Stunnel application was designed to work as an SSL encryption wrapper between remote client and local (inetd-startable) or remote server.

It can be used to add SSL functionality to commonly used inetd daemons like POP2, POP3, and IMAP servers without any changes in the programs' code. 

This software uses OpenSSL or SSLeay libraries for cryptography, so it will support any cryptographic algorithm you have compiled into your library.
