Create and Upload Files to Your Github Private Repository

If you created a public repository in your GitHub account, you can easily send your local code files to that repository without any additional setup.

But If you want to upload your files to a private repository, so that no one can see and access your code, you need to do some simple settings.

First, you need to generate SSH keys on your computer and you have to add that keys to your GitHub Account.

So that Github can understand, the system accessed that private repository is yours.

Step 1: You must install Git on your system & configure the git username and email
Before that, your system must have the Git application.

Make sure to Download and install the Git application on your system.
Open Cmd and type the following commands to set your username:& email address for Git

git config --global user.name "FIRST_NAME LAST_NAME"
git config --global user.email "MY_NAME@example.com"

Replace the “FIRST_NAME LAST_NAME” with your actual name and “MY_NAME@example.com” with your email address.

Note: When typing a command on cmd, if it shows the error like”‘git' is not recognized as an internal or external command, operable program or batch file.' Then you need to add Git path in environment variables. Reference

Step 2: Generate SSH keys on your computer and add that keys to your Github account.

To Generate SSH keys

Open Git Bash and paste the following code

$ ssh-keygen -t ed25519 -C "your_email@example.com"

Just replace the email with your email.

Just press Enter, Enter, Enter

It will automatically generate the SSH key.

Note: It will show the public key saved location on your system. Go to that location. Open the file in Notepad. Copy the whole key and paste it into Github Settings.

Now you have to add that SSH keys on your GitHub account 

1. Then go to Github.com
2. Sign into your account
3. On the top right corner of the screen, click your profile image and Choose Settings.
4. On the left side of the screen, you can see the “SSH and GPG keys” option in the Access section.
5. Just click it.
6. Press the New SSH key button and add the SSH keys you generated on your computer.

Step 3: Create a private repository on GitHub and upload the files from your local computer to that repository

Now let's see how to upload files in a private repository

First, create a new private repository..

For that

1. Go to github.com and Sign into your account.
2. Then Click the New button on the left side of the screen to create a new repository.
3. Enter the repository name and select the Private option.
4. Then click the  “Create repository” option.

Now you have a private repository without any files in it.

Then on your system, go to the folder you want to upload.

Right-click and choose “Git Bash here”. Then type the following commands

git init
git add .
git status

Then you can find the following commands in your private repository, select the SSH tab and copy and paste the following codes in Git Bash. Note: This is an example code. You can find the code like this in your private repository.

git commit -m “first commit”
git branch -M main
git remote add origin git@github.com:”username with git”
git push -u origin main

That’s all. Your Files will be uploaded to that private repository.

Sometimes you will get an error message like this 

The authenticity of host 'github.com (20.207.73.82)' can't be established.
ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])?

To fix this problem, paste the following code in Git bash

ssh-keyscan github.com >> ~/.ssh/known_hosts

Now try to push the code again using the following command

git push -u origin main
