How to generate public keys for git

How to generate a Git public key? Simply follow these steps: Open a terminal or command prompt; run the ssh-keygen -t rsa -b 4096 command; select the key saving location; enter a key phrase (optional); verify that the key has been created; copy the public key; add the public key to Git.

How to generate a Git public key

Generating a Git public key is simple, and it can be done with just the following steps:

Step 1: Open a terminal or command prompt

Open a terminal or command prompt on your computer. For Windows users, you can hold down the Windows key and press R key, and then enter "cmd" to open the command prompt. For Mac and Linux users, terminal applications can be opened.

Step 2: Run the SSH command

Enter the following command to generate the SSH public key:

 <code>ssh-keygen -t rsa -b 4096</code>

• -t rsa specifies the use of RSA encryption algorithm.
• -b 4096 Specifies the number of bits of the key. 2048 bits can be used as a shorter alternative.

Step 3: Select the key saving location

The system will prompt you to enter a key file storage location. Press Enter to accept the default location (usually the .ssh directory), or enter your own path.

Step 4: Enter the key phrase

You will be prompted to enter a key phrase. This is optional, but it is recommended to enter a strong phrase to protect your private key. If you want to skip this step, just press Enter.

Step 5: Verify the key

Run the following command to verify that the key has been successfully created:

 <code>ssh-add ~/.ssh/id_rsa</code>

This will load the SSH private key on your computer.

Step 6: Copy the public key

Your public key is now stored in the .ssh/id_rsa.pub file. Copy the public key using the following command:

 <code>cat ~/.ssh/id_rsa.pub</code>

This will output your public key to the terminal or command prompt.

Step 7: Add the public key to Git

Add your public key to Git so that you can authenticate your Git operations via SSH. Go to a Git repository site like GitHub or GitLab, navigate to your profile settings, and paste your public key into the SSH key field.
