What is the role of GitLab encryption key? How to generate?

GitLab is an open source code hosting platform that provides developers with many convenient operations, such as version control, collaborative development, automated deployment, etc. In the development process using GitLab, in order to ensure the security of the code, we need to use encryption keys to protect our code. Let’s find out below.

The role of GitLab encryption key

On GitLab, we often need to share code with other developers, and we need to upload the code to the GitLab server. In order to ensure the security of the code, we need to encrypt the code. GitLab uses the SSH protocol to encrypt encoding and data transmission, so we need to set an encryption key to protect and encrypt the data.

Generation of GitLab encryption key

First, we need to generate an encryption key for GitLab.

1. Open a terminal window and enter the following code.

ssh-keygen -t rsa -C "你的邮箱地址"

Here we are using the ssh key algorithm. If you have not installed the ssh client, please install it first. This command will generate a new pair of keys for GitLab, including a private key and a public key. We can enter the key storage address and password as needed, or we can directly follow the default settings.

2. Set up the public key

In GitLab, we need to add the public key to your account. Copy the public key and click "Settings" -> "SSH Keys" -> "Add Key" in GitLab to copy the public key into the PublicKey box.

In this way, GitLab will establish a connection with your machine. If an error occurs at this time, please check whether the public key is correct or whether there are irrelevant parts in the public key.

3. Verify whether the key is valid

Enter the following command:

ssh -T git@gitlab.com

If you see the "Welcome to GitLab" welcome message, it means that your GitLab Key has been set It worked.

Summary

In GitLab, encryption keys are an important tool used to protect code. Using the above steps, you can make your GitLab code more secure and avoid unnecessary code leaks and data loss.
