A CA file has been bootstrapped using certificates from the system keychain. To add additional certificates, place .pem files in /usr/local/etc/[email protected]/certs
[email protected] is keg-only, which means it was not symlinked into /usr/local, because openssl/libressl is provided by macOS so don't link an incompatible version.
If you need to have [email protected] first in your PATH run: echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bash_profile
