EasySSL

EasySSL is a C++ free open-source library that enables you to establish an encrypted SSL/TLS connection. You may use EasySSL for a client or a server. EasySSL is made to be simple to use, and always supplies default classes that provides full security. EasySSL is fully documented and won't overwhelm you with numerous functions and classes. EasySSL is a wrapper of OpenSSL or GnuTLS (two different releases), and thus relies on them to provide encryption. Note that the API of EasySSL remains the same regardless of the underlying library.
