Stunnel是一个自由的跨平台软件，用于提供全局的TLS/SSL服务。针对本身无法进行TLS或SSL通信的客户端及服务器，Stunnel 可提供安全的加密连接。该软件可在许多操作系统下运行，包括Unix-like系统，以及Windows。Stunnel依赖于某个独立的库，如 OpenSSL或者SSLeay，以实现下面的TLS或SSL协议。Stunnel由Michal Trojnara 和 Brian Hatch负责维护，遵照GPL许可证进行发布。
stunnel - multiplatform SSL tunneling proxy
The stunnel program is 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. Stunnel uses OpenSSL libraries for cryptography, so it supports whatever cryptographic algorithms you compiled into your library.
Stunnel is a free software authored by Michal Trojnara. Although distributed under GNU GPL version 2 or later with OpenSSL exception, stunnel is not a community project. We retain the copyright of the source code. Please contact us for support or non-GPL licenses.
