Updating OpenSSL to 1.1.1 on MacOS

Question

The new LTS 1.1.1 version of OpenSSL is out.

How can I upgrade to it using homebrew on MacOS?

Solution 1

Using brew:

brew update
brew install [email protected]
echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bash_profile
# Verify 
openssl version
# OpenSSL 1.1.1c  28 May 2019

Solution 2

https://stackoverflow.com/a/56639316 is a good canonical answer, but if you're looking for something simpler / one-off you may be able to get by with just this:

$ brew install [email protected]
$ /usr/local/opt/openssl/bin/openssl version
OpenSSL 1.1.1g  21 Apr 2020

So you could do something like this for example:

$ /usr/local/opt/openssl/bin/openssl rand -hex 32

If you don't have brew on your computer you can install it in one-line by following the instructions here:

$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
