Questions tagged [stunnel]

Stunnel is a small tool that can wrap the connection of other protocols with SSL/TLS.

Stunnel is a free software based on OpenSSL providing a SSL/TLS encryption wrapper between remote clients and a local 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. Stunnel uses the OpenSSL library for cryptography, so it supports whatever cryptographic algorithms are compiled into the library.

For more information, see the homepage of the project at stunnel.org.
