openssl@3: stable 3.0.0 (bottled) [keg-only]
Cryptography and SSL/TLS Toolkit
https://openssl.org/
Not installed
From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/openssl@3.rb
License: Apache-2.0
==> Dependencies
Required: ca-certificates ✔
==> 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@3/certs

and run
  /usr/local/opt/openssl@3/bin/c_rehash

openssl@3 is keg-only, which means it was not symlinked into /usr/local,
because macOS provides LibreSSL.
