Keg-only because this is an alternate version of another formula.

Depends on:

ca-certificates 2026-09-25 Mozilla CA certificate store

Binaries: c_rehash, openssl

To add additional certificates, place .pem files in
    $HOMEBREW_PREFIX/etc/openssl@3/certs

and run
    $HOMEBREW_PREFIX/opt/openssl@3/bin/c_rehash

OpenSSL 3.6 is only supported until 2026-11-01 so the `openssl@3`
formula will be downgraded to OpenSSL 3.5 (LTS) in a future update.
