How to add a key in gitlab

GitLab is a very popular code hosting platform that supports multi-person collaborative development and version control. GitLab provides a very good way to manage and maintain code. This article will show you how to add a key on GitLab.

1. What is GitLab key

GitLab key is a very important component. It allows your team members to effectively use GitLab for code hosting while also ensuring code security.

GitLab key consists of two parts: public key and private key.

The public key is a file used for authentication and is added to your GitLab account. The private key is saved locally and is used to communicate with the GitLab server.

Through a series of complex calculations and verification processes, GitLab keys ensure the security of code transmission and prevent unauthorized users from accessing your code repository.

2. How to generate public and private keys

First, open the ssh-keygen tool in your terminal. This tool will be used to generate public and private keys.

$ ssh-keygen

Next, enter your name and email as prompted in the terminal, then press Ctrl C to exit.

Note: If you already have an ssh key, you can skip this step and use the existing key directly.

Next, use the following command to output your public key:

$ cat ~/.ssh/id_rsa.pub

Copy the output to the clipboard to add it to your GitLab account later.

In the "Title" column below, add a descriptive name for the key so you can find it later.

Click "Add Key" to complete the addition.

4. How to add the private key to the local

If you are using Mac or Linux, just enter the following command in the terminal:

$ ssh-add ~/.ssh/id_rsa

If you are using If you use Windows, you need to install Git Bash (a Linux terminal simulated under Windows) and use the above commands in Git Bash.

5. How to verify the key

Enter the following command in the terminal to verify whether the key has been added successfully:

$ ssh -T git@gitlab.com

If you receive a message confirming that the key has been successfully added and a connection has been established with the GitLab server, the operation is successful.
