One effective way of securing SSH access to your cloud server is to usea public-private key pair. This means that a public key is placed onthe server and a private key is placed on your local workstation.Using a key pair makes it impossible for someone to log in by using justa password, as long as you set up SSH to deny password-basedauthentication.
Generate RSA keys with SSH by using PuTTYgen
You’re looking for a pair of files named something like iddsa or idrsa and a matching file with a.pub extension. The.pub file is your public key, and the other file is your private key. If you don’t have these files (or you don’t even have a.ssh directory), you can create them by running a program called ssh-keygen, which is provided with the SSH package on Linux/Mac systems.
This article provides steps for generating RSA keys by using PuTTYgen onWindows for secure SSH authentication with OpenSSH.
Generate keys
In Windows, use PuTTYgen to generate your public and private keys.
Use the key pair
You can use the RSA key pair in the following ways.
Specify your SSH key when creating a new cloud server
When you create a cloud server, you can assign a public key from the list of keys.If your key is not already in the list, you may add it, and then assign it.
Add a new public key to the list
Assign a public key
Assign your SSH Key to an existing cloud server
To make use of your newly generated RSA key pair, you must tell PuTTY touse it when connecting to your cloud server.
After you save your session, your key is loaded automatically when youconnect to your server.

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 everask 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 locationso you can authenticate with Gerrit.
To generate SSH keys in Mac OS X, follow these steps:
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 private key is saved to the
id_rsa file in the .ssh subdirectory of your home directory and is used to verifythe 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 copyit to your clipboard using the following command:
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 ~/.ssh/config file which would contain the following sections then:
