You can use these signed certificates in a variety of situations, such as to secure connections to a web server or to authenticate clients connecting to a service. We will be signing certificates using our intermediate CA. You should avoid custom build systems because they often miss details, like each architecture and platform has a unique opensslconf.h and bn.h generated by Configure. OpenSSL is configured for a particular platform with protocol and behavior options using Configure and config.I just (in June 2016) ran the following instructions to update Openssl (in /usr/local/openssl) on my Mac, but when I check the version, it's showing that I'm using a version built in 2015 (the System/Library/OpenSSL version).$ port installed openssh The following ports are currently installed: openssh (active) $ port installed openssl The following ports are currently installed: openssl (active) Last but not least, I have tried uninstalling and installing openssl but I'm still getting the above message.
