-f This is the option to specify the source filename.Apple is currently rolling out macOS Sierra, a major update to the Mac operating system.-e This option reads a private or public key and allows exporting keys.This command is available in macOS by default. ssh-keygen This is the command to generate, manage and convert authentication keys for ssh.ssh-keygen -e -f private_key.pem > public_key.pem

The following command exports a public key that is paired with the private key. Export the public keyĬurrently, there is only a private key available. (No permission to write or execute even for the user.) 3. Note: 0400 means that only the user can read the file. Use the following command to change the file permission. Once the key has been generated, change the file permission to protect such sensitive information. The longer length will enhance the security, however, it will take more time to process. In this case, rsa_keygen_bits:2048 specifies the length of the generated key. Available options for the command are listed here. -pkeyopt rsa_keygen_bits:2048 The -pkeyopt option sets the public key algorithm.In this case, the filename would be ‘private_key.pem’. -out private_key.pem Output the key with the specified file.-outform PEM Specifies the output format.The -aes-256-cbc cypher will encrypt the key and asks for a password to use. According to the OpenSSL documentation, any algorithm accepted by EVP_get_cipherbyname() is acceptable. A cypher is an algorithm for performing encryption or decryption. -aes-256-cbc This option specifies the cypher used to encrypt the private key.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.
