On macOS Big Sur, how do I get the version of OpenSSL installed through Homebrew to be what is used on the command line?

I’m on macOS Big Sur. I installed OpenSSL via Homebrew like this:

$ brew install openssl
Updating Homebrew...
==> Auto-updated Homebrew!
Updated Homebrew from 40a7a0119 to f50b87031.
Updated 2 taps (homebrew/core and homebrew/cask).

==> Updated Casks
Updated 19 casks.

Removing: /Users/davea/Library/Caches/Homebrew/[email protected]... (5.4MB)

The above seems to imply I have already installed version 1.1.1, but when I check on the command line, I see the following:

$ openssl version
LibreSSL 2.8.3
$ which openssl
/usr/bin/openssl

Where is this newer version of OpenSSL coming from and how can I make the versions consistent on my machine?

You could add something like this to your shell so that your environment picks up brew version.

export PATH="/usr/local/opt/openssl@1/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/openssl@1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1/include"
