Generate SSH Key Pair: You can generate an SSH key pair using the ssh-keygen command.
```
ssh-keygen -t rsa -b 4096 -C "email@example.com"
```
- -t rsa: Specifies the RSA algorithm.
- -b 4096: Uses a 4096-bit key.
- -C "email@example.com": Adds a label (optional).
When prompted, you can specify a file to save the key (e.g., ~/.ssh/id_rsa), or press Enter to accept the default. You may also be prompted to enter a passphrase (optional, but recommended).
Copy the Private Key: After generating the key, you will have two files: the private key (id_rsa) and the public key (id_rsa.pub). You need to copy the contents of the private key file.
```
cat ~/.ssh/id_rsa
```
Copy the entire content of the file including this:

-----BEGIN RSA PRIVATE KEY-----
MIIEpAIBAAKCAQEA7...
...
-----END RSA PRIVATE KEY-----

Or use

cat ~/.ssh/id_rsa.pub

This should output something like:

ssh-rsa AAAAB3... user@example.com

Alternatively, on Windows, you can use:

type %userprofile%\.ssh\id_rsa.pub

Or using git CLI:

cat ~/.ssh/id_rsa.pub

Add the Public Key to the server: On your VPS server, add the public key to the ~/.ssh/authorized_keys file. You can do this by appending the content of the public key file to authorized_keys:
```
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
```

Navigate to Your Repository: Go to your repository on GitHub.
Go to Settings: Click on Settings in the top menu.
Create a Secret:
- In the left sidebar, click on Secrets and variables, then Actions.
- Click on New repository secret.
- Set the Name to SSH_PRIVATE_KEY.
- Paste the contents of your private key file into the Value field.
- Click Add secret.

In your GitHub Actions workflow, you can use the secrets by referencing them like $. Here’s an example snippet:

- name: Set up SSH
  uses: webfactory/ssh-agent@v0.5.3
  with:
    ssh-private-key: $
