Creating a SSH Public Key on OSX
You generate an SSH key through Mac OS X by using the Terminal application. Once you upload a valid public SSH key, Gerrit can authenticate you based on this key.
An SSH key consists of a pair of files. One is the private key, which you
should never give to anyone. No one will ever
ask you for it and if so, simply ignore them - they are trying to steal it.
The other is the public key. When you generate your keys, you will
use ssh-keygen
to store the keys in a safe location so you can
authenticate with Gerrit.
To generate SSH keys in Mac OS X, follow these steps:
-
Enter the following command in the Terminal window:
ssh-keygen -t ed25519
Copied!This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key.
- Press the
ENTER
key to accept the default location. The ssh-keygen utility prompts you for a passphrase. - Type in a passphrase. You can also hit the
ENTER
key to accept the default (no passphrase). However, this is not recommended.
Warning
You will need to enter the passphrase a second time to continue.
After you confirm the passphrase, the system generates the key pair and you will see output like this:
Your identification has been saved in /Users/yourmacusername/.ssh/id_ed25519.
Your public key has been saved in /Users/yourmacusername/.ssh/id_ed25519.pub.
The key fingerprint is:
ae:89:72:0b:85:da:5a:f4:7c:1f:c2:43:fd:c6:44:38 yourmacusername@yourmac.local
The key's randomart image is:
+--[ RSA 2048]----+

Your private key is saved to the id_rsa
file in the .ssh
subdirectory
of your home directory and is used to verify the public key you use belongs to
your Gerrit account.
Warning
Never share your private key with anyone! Ever! We mean it!
Your public key is saved to a file called id_rsa.pub
in the .ssh
subdirectory of your home directory. You can copy it to your clipboard using
the following command:
pbcopy < ~/.ssh/id_ed25519.pub
Now you can head over to Gerrit_, go to settings and paste your public key as described here.
Gerrit is using the special port 29418
instead of the default SSH port 22
which has to be configured accordingly. This can be done in your local
~/.
file which would contain the following sections then:
Host review.typo3.org
Port 29418
Testing your connection:
ssh -T <YOUR_TYPO3_USERNAME>@review.typo3.org
