speidy	a432969746	common: ssl_calls: add support for OpenSSL>=1.1.0 API for DH keys ... also fixes some memory leak introduced in PR#1024. and adds a check that DH params generated successfully. write a proper log message if not.	7 years ago

Enrico Tagliavini	70b5adb396	add support for DHE ciphers via compiled in dhparam ... make it possible to use regular (non EC) EDH ciphers. To make this possible a Diffie-Hellman parameter must be passed to the openssl library. There are a few options possible as described in the manuals at [1] and [2]. Simplest approach is to generate a DH parameter using openssl dhparam -C <lenght> and include the code into the application. The lenght used for this commit is 2236 bits long, which is the longest possible without risking backward incompatibilities with old systems as stated in [1]. Newer systems should use ECDH anyway, so it makes sense to keep this method as compatible with older system as possible. Paramters longer than 2048 should still be secure enough at the time of writing.

Enrico Tagliavini	6cdc0f31b0	enable automatic ECDH when possible (openssl 1.0.2) ... Openssl 1.1.0 and later are enabling ECDH automatically, but for older version it must be enabled explicitly or all Perfect Forward Secrecy ciphers will be silently ignored. See also [1]. This commit applies the same fix as found in CnetOS 7 httpd package to enable automatic ECDH as found in [2].

Pavel Roskin	6664aac00f	Use "void" for empty argument list in declarations ... In C, an empty argument list in a declaration means that the function can accept any arguments. Use "void" instead, it means "no arguments". C++ treats void and empty list as "no arguments".	8 years ago

Pavel Roskin	4324084d58	Use static inline functions for OpenSSL 1.0 backport ... Conditional preprocessor directives spread throughout the code set a bad example. The new backport code is located in one place. The compiler checks argument types. The backport code has no access to the caller variables. The main code has all advantages of the new, more compact API.	8 years ago
