Git is a popular version control system that allows developers to collaborate on projects by tracking changes to files and sharing them with others. Git uses HTTPS to connect to remote repositories, and in some cases, these repositories may use self-signed certificates. However, Git may reject such certificates by default as they are not issued by a trusted certificate authority. In this blog, we'll discuss how to make Git accept a self-signed certificate.

A self-signed certificate is a certificate that is not issued by a trusted certificate authority. Instead, it's generated by the organization that owns the domain name or IP address of the server. Self-signed certificates are commonly used in development and testing environments, as they are quick and easy to create.

Why does Git reject self-signed certificates?

Git uses HTTPS to connect to remote repositories, and by default, it only accepts certificates that are issued by a trusted certificate authority. This is because self-signed certificates are more susceptible to security risks, such as man-in-the-middle attacks. As a result, Git may reject self-signed certificates by default.

How to make Git accept a self-signed certificate?

Here are the steps to make Git accept a self-signed certificate:

Add the certificate to the trusted certificates store:

The first step is to add the self-signed certificate to the trusted certificates store on your system. You can do this by running the following command in your terminal:

sudo cp path/to/certificate.crt /usr/local/share/ca-certificates/certificate.crt

Replace path/to/certificate.crt with the path to your self-signed certificate. This command will copy the certificate to the trusted certificates store.

Once you've added the certificate to the trusted certificates store, you need to update it. You can do this by running the following command in your terminal:

This command will update the trusted certificates store with the new certificate.

Configure Git to use the trusted certificates store:

The final step is to configure Git to use the trusted certificates store on your system. You can do this by running the following command in your terminal:

git config --global http.sslCAInfo /etc/ssl/certs/ca-certificates.crt

This command will configure Git to use the trusted certificates store when connecting to remote repositories over HTTPS.

Making Git accept a self-signed certificate is essential when working with repositories that use self-signed certificates. By following the steps outlined in this blog, you can easily add the self-signed certificate to the trusted certificates store and configure Git to use it when connecting to remote repositories over HTTPS. This will ensure that you can collaborate on projects without any issues and keep your data secure.

This blog explains how to make Git accept a self-signed certificate by adding it to the trusted certificates store and configuring Git to use it when connecting to remote repositories.

How can I make git accept a self-signed certificate?

In order to ease development i want to serve the necessary TM @require files through a localhost HTTP(S) server. I expected these files to be reloaded on each page reload.

The files are fetched from the localhost server when i update the UserScript in the TM editor, however, they are not fetched when a matched URL is loaded. I'm not sure if this is a caching thing by TM or if i'm doing something wrong here.

To separate concerns in the JS files, the UserScript header is separated from other logic. The necessary files are imported using @required. This is the content of the UserScript file that is pasted in the TM editor:

// ==UserScript==
// @name            myName
// @description     myDescription
// @author          robinlarondelle
// @version         0.1
// @namespace       myNameSpace
// @homepage        myHomePage
// @include         *linkedin.com/*
// @icon            https://www.google.com/s2/favicons?domain=linkedin.com
// @grant           window.onurlchange
// @require         https://localhost:3000/public/myScript.user.js
// ==/UserScript== 


The localhost HTTPS static file server is a Node.JS server with a self signed certificate to enable HTTPS. When using Postman and FireFox after providing my .pem file, the server works as expected. If necessary i can provide more details about the server, but i don't think the problem resides here.

The main question/problem is: Why does @require from the UserScript header only fetch the required files on Script Save in the TM editor, but not on Page Reload when the URL matches? Is this normal behavior and/or can we turn this off?

Are all URLs encrypted when using TLS/SSL (HTTPS) encryption? I would like to know because I want all URL data to be hidden when using TLS/SSL (HTTPS).

If TLS/SSL gives you total URL encryption then I don't have to worry about hiding confidential information from URLs.

I am the use of an HTTPS server to host a git server but for now, the certificates are self-signed.
