GitHub is a popular version control system and source code hosting platform used by developers and IT professionals around the world. It is often used to collaborate on projects and share code with other developers. In order to securely access a GitHub repository, users must authenticate with an SSH key. This process can be a bit daunting for less experienced users, especially those unfamiliar with the use of Putty and SSH keys.
The first step to connecting to GitHub using a Putty-generated SSH key is to generate the key. To do this, users must download and install the Putty SSH and Telnet client, which is available for free on the Putty website. Once the software is installed, users can begin creating the SSH key. First, open the PuTTY Key Generator, which can be accessed from the PuTTY folder in the Windows Start menu.
In the PuTTY Key Generator window, select the type of key to generate from the “Type of key to generate” menu. The default option is “SSH-2 RSA”, which is typically the best choice. In the “Number of bits in a generated key” field, the default value of “2048” is usually sufficient. Then, click the “Generate” button to generate the key.
After the key is generated, the user will be prompted to enter a passphrase. This passphrase is used to protect the key and should be kept secret. Once the passphrase has been entered, PuTTY will generate the key and display it in the window.
The next step is to save the key to a file. To do this, click the “Save public key” button to save the public key portion of the key in a file. Then, click the “Save private key” button to save the private key portion of the key in a file. It is important to note that the public and private keys must be stored in two separate files.
Once the keys have been generated and saved, the user can add the public key to the GitHub account. To do this, the user must log in to their GitHub account and navigate to the “SSH and GPG keys” page, which can be found in the “Settings” section. On this page, click the “New SSH key” button and enter a name for the key. Then, paste the public key into the “Key” field and click “Add SSH key”.
Once the public key is added to GitHub, the user can connect to their account using their private key. To do this, the user must open the PuTTY SSH client and enter their GitHub username and the path to the private key file in the “Host Name” field. Then, click the “Open” button to connect to the account.
Once the connection is established, the user can begin working with their GitHub repository. The user can push and pull files, commit changes, and collaborate with other developers on the repository.
In conclusion, connecting to GitHub using a Putty-generated SSH key is not a difficult process. By following the steps outlined in this article, users can quickly and securely connect to their GitHub account with the help of the PuTTY SSH and Telnet client.
