You’ll now be returned to the summary screen that will show your key with a new subkey listed.
Enter whatever expiration date you’d like using the options on the screen and then press Y then Return.įinally you’ll be asked if you’re ready to create Really create? (y/N) and you can continue by pressing Y then Return. It’s a good idea to set this to the same expiration date of your master key as if you pick an earlier date, your key will stop functioning for authentication on that date. You’ll now have to enter an expiration date for your subkey. When asked for a key size, enter 4096 and press Return. If it doesn’t, toggle the options using the keys above until only ‘Authenticate’ is listed. The output should now read Current allowed actions: Authenticate, with nothing else listed on that line. In association with the KMail email client, you can also take advantages of the cryptographical features for your communication via email.

The software stores your OpenPGP certificates and keys. Press A then Return to toggle the Authenticate action on Kleopatra is a certificate manager and GUI for GnuPG. Press E then Return to toggle the Encrypt action off Press S then Return to toggle the Sign action off By default it selects both the sign and encrypt actions, so we need to toggle both of these off, and then toggle authentication on. Now we need to tell GPG which actions we would like this subkey to perform. Select (8) RSA (set your own capabilities) by entering 8 and pressing Return. You’ll now be prompted to select the type of key you want to add.

My preferred method is to use the Homebrew package manager to quickly install the command line version. a remote server with SSH key-based authentication enabledīefore we can make use of GPG keys on your local machine, we need to install a variant of GnuPG.the Keybase client installed on your local machine.Where this really shines is when you use your Keybase client as your GPG credential manager so you can quickly and easily manage your keys wherever you need them. The main benefit of this approach is that you don’t need to manage different sets of keys for authentication and signing/encryption as both can belong to the same keyring. This simplifies the process of logging into remote servers while protecting your user credentials, however managing these keys can quickly become a frustration when you have to use many servers across different environments.Ī useful alternative to managing SSH keys is to instead use a GPG key for authenticating SSH sessions. You can further automate this by using the ssh-agent process to provide your key automatically when initiating an SSH session. You then pass this key to your SSH client when connecting to remote servers that have a copy of your public key in their authorized_keys file and login without needing to type a password. Without explaining how the process works in detail, normally you would generate an RSA key-pair to use with SSH and this file will be stored on your local machine in ~/.ssh/. For this reason, many servers are configured to accept public key authentication as an alternative method of verifying identity.

If you already installed gpgOSX before, simply double click on password authentication is the default method most SSH (Secure Shell) clients use to authenticate with remote servers, there’s plenty of potential security vulnerabilities with this approach.
