A CA file has been bootstrapped using certificates from the SystemRoots

the System keychain ) , place . pem files in
  / usr / local / etc / openssl / certs
 
and run
  / usr / local / opt / openssl / bin / c_rehash
 
openssl is keg - only , which means it was not symlinked into / usr / local ,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries .
 
If you need to have openssl first in your PATH run :
   echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' > > ~ / . bash_profile
 
For compilers to find openssl you may need to set :
   export LDFLAGS = "-L/usr/local/opt/openssl/lib"
   export CPPFLAGS = "-I/usr/local/opt/openssl/include"
