What kind of TLS certificate is supposed to be added to github for TLS certificate renewal? I uploaded cert+chain and key. But it still fails. Any help?

@Hitesh1438 hi, You don’t need to upload your own TLS certificate to GitHub. GitHub automatically manages and renews TLS certificates for github.com, GitHub Pages, and custom domains (via Let’s Encrypt)
If you’re trying to set up HTTPS for a custom domain on GitHub Pages, the only requirement is that your DNS is configured correctly (A/AAAA or CNAME records pointing to GitHub). GitHub will then provision and renew the TLS cert for you.
Manually uploading certs/keys isn’t supported, which is why your upload is failing.

@Hitesh1438 Hey there! The good news is you don't actually need to upload a certificate yourself.

GitHub Pages handles TLS certificates automatically for free using Let's Encrypt.

If it's failing, the problem is almost always in your domain's DNS settings. Just go to your repository's Settings and then Pages page—GitHub will usually tell you exactly what DNS record is wrong and how to fix it.

The certificate upload on GitHub Pages can be a bit picky. The most common reason it fails is due to an incorrectly bundled certificate chain or a password-protected private key.

## The Correct Certificate Format

GitHub Pages requires two things:

1. A Certificate + Full Chain File: This is a single text file that contains your server certificate first, followed by all the intermediate certificates from your Certificate Authority (CA). The order is critical.
2. A Decrypted Private Key: The private key cannot be encrypted or password-protected.

---

## How to Create the Correct Files

You'll likely need to combine or convert the files your CA provided.

1. Combine Your Certificate and Chain

Your CA usually gives you at least two files: your domain's certificate (e.g., your_domain.crt) and an intermediate bundle (e.g., ca_bundle.crt or chain.crt). You need to combine them into one file.

Open a terminal and use the cat command (on Linux/macOS) or a text editor to combine them. The order must be your certificate first, then the intermediates.

cat your_domain.crt ca_bundle.crt > fullchain.pem

The resulting fullchain.pem is what you will upload to the certificate field on GitHub.

2. Decrypt Your Private Key

If your private key file asks for a password when you try to use it, it's encrypted. You need to decrypt it first.

Run this OpenSSL command:

openssl rsa -in your_encrypted_key.key -out decrypted_key.key

It will ask for your password one last time and save the decrypted version. The decrypted_key.key is what you will upload to the key field on GitHub.

---

## How to Verify Your Files Before Uploading

You can save yourself some trouble by checking that your certificate and private key match before you upload them. Run these two commands:

# Get a hash from your certificate
openssl x509 -noout -modulus -in fullchain.pem | openssl md5

# Get a hash from your private key
openssl rsa -noout -modulus -in decrypted_key.key | openssl md5

If the output strings from both commands are identical, then your key and certificate match, and you should be good to upload them. If they are different, you have a mismatched pair.

By ensuring your certificate chain is bundled correctly and your private key is decrypted, the upload to GitHub Pages should work without any issues.
