This website is good for roughly understanding the differences between each algorithm. You can use other algorithms such as DH, EC and DSA. -algorithm RSA Specifies the algorithm to use it for the key.This command is not supported in the old versions of OpenSSL. genpkey This command generates a private key.openssl genpkey -algorithm RSA -aes-256-cbc -outform PEM -out private_key.pem -pkeyopt rsa_keygen_bits:2048 Remember the password to use the key to decrypt the necessary information later in your apps.

Use the following command to generate the key bundle. GenerateĪt this point, you should be ready. Check OpenSSL version again openssl version 2. You need to press ‘ ⌘ + T’ to change the tab to see the updated result. If you need to have openssl first in your PATH run: echo 'export PATH='/usr/local/opt/openssl/bin:$PATH'' > ~/.bash_profile. openssl: stable 1.0.2t (bottled) SSL/TLS cryptography library. Then, just copy the command there and run it. Run the following command and find the line saying something like If you need to have this software first in your PATH run. Only if you don't have OpenSSL installed brew install openssl // If you already have OpenSSL, update the package brew upgrade opensslĪfter installing or upgrading OpenSSL, we need to specify the path in. If you don’t have OpenSSL installed, use brew install openssl instead. brew list opensslįinally, update OpenSSL. If it returns something, you already have OpenSSL. Next, check if you have OpenSSL installed with the following command. Case 1: You are already using OpenSSL // Update homebrew itself brew update // Update OpenSSL brew upgrade openssl Case 2: You are currently using LibreSSLįirst, update the homebrew itself. If it returns something like LibreSSL 2.8.3, go to check Case 2 of this section. This should return something like OpenSSL 1.0.2t. First, check the version of OpenSSL with the following command. In this article, I stick with the classic OpenSSL. Since High Sierra, Mac adopts LibreSSL instead of OpenSSL by default. First, update the OpenSSL to use the latest features.
