Git Bash Ssh Key Generate
SSH keys are a way to identify trusted computers, without involving passwords. The steps below will walk you through generating an SSH key and adding the public key to the server.
Jul 25, 2019 Go to this address, and download Git for Windows, after the download install it with default settings; Open Git Bash that you just installed (Start-All Programs-Git-Git Bash) Type in the following: ssh-keygen -t rsa (when prompted, enter password, key name can stay the same). Sep 26, 2019 Generating an SSH key. To generate an SSH key with PuTTYgen, follow these steps: Open the PuTTYgen program. For Type of key to generate, select SSH-2 RSA. Click the Generate button. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair. Type a passphrase in the Key passphrase field.
Step 1: Check for SSH Keys
First, check for existing SSH keys on your computer. Open Git Bash, Cygwin, or Terminal, etc. and enter:
Check the directory listing to see if you already have a public SSH key. By default, the filenames of the public keys are one of the following:
- id_dsa.pub
- is_ecdsa.pub
- id_ed25519.pub
- id_rsa.pub
If you see an existing public and private key pair listed (for example id_rsa.pub and id_rsa) that you’d like to use, you can skip Step 2 and go straight to Step 3.
Step 2: Generate a new SSH key
With your command line tool still open, enter the text shown below. Make sure you substitute in your email address:
You’ll be asked to enter a passphrase, or simply press Enter to not enter a passphrase:
After you enter a passphrase (or just press Enter twice), review the fingerprint, or ‘id’ of your SSH key:
Step 3: Add your key to the ssh-agent
To configure the ssh-agent program to use your SSH key, first ensure ssh-agent is enabled.
If you are using Git Bash, turn on the ssh-agent with command shown below instead:
Then, add your SSH key to the ssh-agent:
Step 4: Add your SSH key to the server
To add your public SSH key to the server, you’ll copy the public SSH key you just created to the server. Substitute “username” with your username on the server, and “server.address.com” with the domain address or IP address of your server:
Ssh Key Setup
The server will then prompt you for your password:
That’s it! You should now be set up to connect to the server without having to authenticate.
SSH keys are an access credential used in SSH protocol (Secure Shell) which is a network protocol that helps to login from one computer to another securely, as well as to manage networks, operating systems, and configurations. This snippet is going to help you add an SSH key to the ssh-agent, generate a new SSH key, learn how to find the SSH key of your PC and how to connect it with your GitHub/bitbucket account. You can also find information on the use of SSH keys.
Now let's find out how we can checkout PC's SSH keys.
Checking PC's SSH Keys
Type ls -al ~/.ssh so as to see your ssh keys:
By default, the filenames of the public keys are one of the following:
Generate a new SSH key
Type this below, using your GitHub's account email:
The following text will show up after which you can hit the “Enter” button:
But the problem is, you don't know where the entropy is, so just throwing away some part is problematic. Does a passphrase generate the same key using aes. @marcelm: Given n bits of entropy input and a hash that has mn bits of output, the hash retains all entropy (a password is unlikely to have more entropy than will fit a hash, so let's ignore that case).
In this section, you can hit “Enter” again or type the secure passphrase (more about passphrase).
Adding an SSH key to the ssh-agent
Now let’s find out how we can add the SSH key to ssh-agent. Before adding, check your ssh keys or generate a new key.
- Be sure ssh-agent is enabled:
- Add your SSH key to the ssh-agent. If you used an existing SSH key rather than generating a new SSH key, you would need to replace id_rsa in the command with the name of your existing private key file:
How To Add SSH Key To Github Account
- Log into your Github's account. In the top right corner of any page, click your profile photo, then click Settings.
- In the user settings sidebar, go to SSH and GPG keys.
- Click New SSH key.
- Type Title and your SSH Key.
You can get your ssh key by typing below.
Now you have added your PC's SSH key to your Github's account.
Back up old SSH keys
If there are existing SSH keys, but you do not want to use them for connecting to Bitbucket Server, you should back up these old keys running the following:
Why we need SSH key (for Linux and OSX)
Create New Ssh Key
If you use Git and want to clone anything from remote repositories, you have to choose one of these two ways: HTTPS or SSH. If you use HTTPS, you have to type your account access every time you communicate with the remote repository, or change your configs and fill your account data (access). Another modern way is to use the SSH authentication method. It is used in many Version Control Systems to have command line access into your servers, etc. SSH key pairs can be used for authentication instead of passwords. Each key pair consists of a private key and a corresponding public key. When you use SSH key for Git, you inform Git that this PC is authenticated for that Github account, and it will never ask you about any access again because you have already given it your SSH key.
