Generate SSH key
- Open your terminal
- Run the following command
$ ssh-keygen -t rsa -b 4096 -C "keyword"
, where keyword can be an email or any word which identify this ssh key. After this command you can see in the console the output> Generating public/private rsa key pair
. - In the next step you need to add the file path where to generate the ssh key
> Enter a file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter]
. I suggest to create a new file inside/Users/you/.ssh/
path. Example/Users/you/.ssh/your-file-name
. Please be advised thatyour-file-name
doesn’t have any extension. - Setup a password. If you don’t want you can skip this by pressing ENTER.
> Enter passphrase (empty for no passphrase): [Type a passphrase]> Enter same passphrase again: [Type passphrase again]
Add SSH key to ssh-agent
Until now you generated your SSH key. But this key is not active yet. You need to activate it, so execute the command:
$ ssh-add -K ~/.ssh/your-file-name
Copy the public key
On your local computer run the following command and copy the output
$ cat ~/.ssh/your-file-name.pub
Add the public key on remote server
Then go on your hosting server and open the file ~/.ssh/authorized_keys
with whatever tool you prefer, vim, nano or something else, append at the end of file what you copy previously and save the file.
You’re ready to go and use your new ssh key.
