How to add a passphrase?

To add a passphrase when generating an SSH key, follow these steps:

1. Open your terminal.

2. Run the ssh-keygen command:

   ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

3. When prompted for the file location:

   • Press Enter to accept the default location (e.g., ~/.ssh/id_rsa).

4. When prompted for a passphrase:

   • Type your desired passphrase. This passphrase will be used to encrypt your private key.
   • Press Enter.

5. When prompted to confirm the passphrase:

   • Type the same passphrase again and press Enter.

After completing these steps, your SSH key will be generated with a passphrase. You will need to enter this passphrase each time you use the private key for SSH connections.
