Although we are derived from 1.0.2, we mimic 1.1.0 in some ways around our FOO_up_ref functions and opaque libssl types. This causes some difficulties when porting third-party code as any OPENSSL_VERSION_NUMBER checks for 1.1.0 APIs we have will be wrong. Moreover, adding accessors without changing OPENSSL_VERSION_NUMBER can break external projects. It is common to implement a compatibility version of an accessor under #ifdef as a static function. This then conflicts with our headers if we, unlike OpenSSL 1.0.2, have this function. This change switches OPENSSL_VERSION_NUMBER to 1.1.0 and atomically adds enough accessors for software with 1.1.0 support already. The hope is this will unblock hiding SSL_CTX and SSL_SESSION, which will be especially useful with C++-ficiation. The cost is we will hit some growing pains as more 1.1.0 consumers enter the ecosystem and we converge on the right set of APIs to import from upstream. It does not remove any 1.0.2 APIs, so we will not require that all projects support 1.1.0. The exception is APIs which changed in 1.1.0 but did not change the function signature. Those are breaking changes. Specifically: - SSL_CTX_sess_set_get_cb is now const-correct. - X509_get0_signature is now const-correct. For C++ consumers only, this change temporarily includes an overload hack for SSL_CTX_sess_set_get_cb that keeps the old callback working. This is a workaround for Node not yet supporting OpenSSL 1.1.0. The version number is set at (the as yet unreleased) 1.1.0g to denote that this change includes https://github.com/openssl/openssl/pull/4384.

BoringSSL
BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
