Unable to resolve "unable to get local issuer certificate" using git on Windows with self-signed certificate

Resolving "unable to get local issuer certificate" Error in Git on Windows with a Self-Signed Certificate

So you've encountered the frustrating "unable to get local issuer certificate" error while using Git on Windows with a self-signed certificate. Don't worry, we've got you covered! In this blog post, we'll address the common issues surrounding this error and provide easy solutions to help you get back on track.

Understanding the Problem

The "unable to get local issuer certificate" error occurs when Git or cURL (which Git relies on for HTTPS connections) cannot validate the SSL certificate presented by the server. In your case, it's specifically related to using a self-signed certificate on your server.

Solution 1: Add the Certificate to Git's Trusted Store

Typically, adding the self-signed certificate to the Trusted Root Certification Authorities on your Windows machine would resolve this issue. However, Git and cURL use their own certificate store separate from the client machine's store.

To overcome this, there is a workaround provided in a blog post by Philip Kelley (source). The blog post suggests creating a private copy of curl-ca-bundle.crt, a bundle of trusted certificates, and configuring Git to use it.

1. Follow the steps in the blog post to create and configure your private copy of curl-ca-bundle.crt. Ensure that Git is using your copy by verifying that Git complains when you rename the file.

2. With your custom curl-ca-bundle.crt in place, attempt to use Git with the self-signed certificate.

If this solution works, congratulations! You've successfully resolved the issue. However, if you're still greeted with the same error message, let's explore alternative solutions.

Solution 2: Disabling SSL Verification (Use with Caution)

Please note that disabling SSL verification is not recommended as it compromises the security of your communications. Use this solution only if you are working in a safe and controlled environment.

To disable SSL verification in Git:

1. Open a Command Prompt or Git Bash.

2. Run the following command:

   git config --global http.sslVerify false

With SSL verification disabled, Git will no longer check the validity of SSL certificates. This should allow you to proceed with your Git operations using the self-signed certificate.

Solution 3: Ensure the Certificate Chain is in Place

In your case, since you mentioned that your certificate is self-signed and acts as the root certificate, there might not be a chain for Git/cURL to follow. However, it's worth double-checking to ensure that there is no missing intermediate certificate.

If you have access to the server hosting the self-signed certificate, you can try generating a certificate chain and include it in the server configuration. This process varies depending on the server software you're using, so consult the documentation or seek assistance from your system administrator.
