$ clip < ~/.ssh/rsa.pub

​

To set up an SSH key for secure authentication with your Git repositories, follow these steps:

​

**Generating an SSH Key:**

​

1. Open a terminal window and create an SSH key by executing the following command:

   $ ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

​

**Choosing a Key File Name:**

​

2. Choose a meaningful name for your key file based on the service you're using, such as `github_rsa` for GitHub or `gitlab_rsa` for GitLab.

​

**Copying the Public Key:**

​

3. Copy the public key to your clipboard from the following path:

​

   $ ~/.ssh/github_rsa.pub

​

   Note: If you didn't specify a name during key generation, it will be saved as `id_rsa.pub` by default.

​

**Adding the Key to Your GitHub Account:**

​

4. Navigate to your GitHub account and access the SSH keys settings page.

​

5. Click on "New SSH Key."

​

6. Paste the SSH key from step 3 into the "Key" field and provide a descriptive title.

​

7. Click "Add Key" to complete the process of adding the SSH key to your GitHub account.

​

--------------

In case you encounter a "permission denied" issue, follow these additional steps:

​

**Resolving Permission Issues:**

​

1. rename known_hosts to known_hosts.old

​

   $ mv ~/.ssh/known_hosts ~/.ssh/known_hosts.old

​

2. Run the following command to start the SSH agent:

​

   $ eval "$(ssh-agent -s)"

​

3. Add your SSH key to the agent:

​

   $ ssh-add ~/.ssh/github_rsa

​

--------------

note: if the problem still exist read the following.

​

You need to tell Git which SSH key to use when connecting to GitHub.

You can do this by editing your: 

~/.ssh/config 

file or creating it if it doesn't exist.

Add the following lines to the file which name is config:

Host github.com

  HostName github.com

  User git

  IdentityFile ~/.ssh/github_rsa

​

By following these steps, you'll establish a secure SSH key-based authentication method for your Git interactions, ensuring a smoother and more secure workflow.

1. ssh-keygen -o -t rsa -C "your_email@example.com"

2. Press return for each option

3. cat ~/.ssh/id_rsa.pub

4. Copy the entire cat's output on "Settings - SSH and GPG keys - New SSH key" on GitHub

1. ssh-keygen

2. cd ~/.ssh

3. cat id_rsa.pub

4. copy key
