Stunnel is proxy management and network security utility that enables users to create safe and secure encrypted connections about PCs that are not equipped to take care of TSL and SSL standards natively. Created as an open-source application under primary advancement its creator Michał Trojnara, Stunnel has managed very rapidly to turn into one of the first solutions intended for networking and security professionals who would like to put TLS encryption functionality to their community nodes (both servers and clients) with no actively changing the code of typically the communication and data sharing programs. To be able to provide as high security as that is possible, Stunnel depends on tried and even tested public-key cryptography with X. 509 digital certificates to create an inexplicable SSL connection. The security is taken care of via advanced OpenSSL libraries and user-selected cryptographic algorithms, a FIPS 140-2 acceptance, and much more. Originally released to be able to the public in December of 98, this application went through several huge upgrades that enabled it to get suitable for use both by residence users and large companies. The usage of new security, portability, and scalability features enabled all of its consumers to adopt direct control over network safety measures. After more than 16 years about the market, Michał Trojnara released one other more feature-rich online security app Ghostunnel – which was marketed as a new successor to Stunnel. It can get downloaded and used for FREE by simply both home users and businesses. Typically the app is optimized for all modern day versions of Windows OS and could be also available on a wide selection of other OS and device websites.
