==> Using the sandbox

==> Caveats

A CA file has been bootstrapped using certificates from the system

keychain. To add additional certificates, place .pem files in

  /usr/local/etc/openssl/certs

and run

  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local.

Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries

Generally there are no consequences of this for you. If you build your

own software and it requires this formula, you'll need to add to your

build variables:

    LDFLAGS:  -L/usr/local/opt/openssl/lib

    CPPFLAGS: -I/usr/local/opt/openssl/include

==> Summary

��  /usr/local/Cellar/openssl/1.0.2h_1: 1,691 files, 12M
