Git: Creating an SSH Key for BitBucket
Git: Basics Git'N Started
Today, we are starting with the basics of using Git and Version control: creating an SSH Key. For beginners, it can seem a little daunting or confusing, but I assure you, once you perform it a few times it will feel so simple.
Why Create an SSH Key?
Using an SSH Key registers your PC so you no longer need to use login credentials when performing any commands using git. Once registered, the SSH key is passed to the external server and verifies that you are the user of the account on their server, i.e. your Github or BitBucket account.
Step 1: Generate It
cd ~ and type:
ssh-keygen. From there, you will be asked to name your ssh key. It's optional, but if you have a few different accounts, it's worth giving it a unique name. It will also prompt you to generate a password, again, this is optional. For more information about using passwords when generating SSH keys, check out this Digital Ocean article.
To see your generated SSH key, type
dir .ssh and it will output your files;
<username>@<PC_name> MINGW64 ~ $ dir .ssh id_rsa id_rsa.pub known_hosts
Next, we're going to add the key to the agent. To do that, we need to start the agent by typing
eval $(ssh-agent). After it outputs the
Step 2: Add the SSH Key to Bitbucket
Under your account settings, found on the lower left by clicking your avatar image and selecting
settings. Find the
SSH option on the left side-bar. Click
Add SSH Key and give your key a name.
Now, back in your Git terminal, type
cat ~/.ssh/<private_key>.pub, copy the output and paste it into the SSH field on Bitbucket. Hit Save.
Step 3: Verify your SSH Key
In the terminal, type
ssh -T firstname.lastname@example.org:<username>/<repo>.git. The output will inform you if everything has completed successfully. Odds are, it will be just fine.
Step 4: Code
