  Message : Make SSL_library_init() a wrapper of OPENSSL_init_ssl() This way it doesn't do nonsensical work for all those who cargo culted an init sequence. There's no point in having SSL_library_init() as a cheaper version of OPENSSL_init_ssl(): once you do crypto, you'll init crypto... Also move the now trivial implementation to ssl_init.c which has a good license. ok jsing
