Understanding SSH Keygen

SSH keygens serve as sophisticated digital authentication tools, providing a secure alternative to conventional username and password access. Each user receives a unique set of keys, comprising a public key (shared with the server) and a private key (kept confidential). This key pair establishes a secure channel between your computer and the server, ensuring protected communication.

Steps to Generate SSH Keys on Windows

1: Using Command Prompt

  1. Launch the Windows Terminal or Command Prompt.
  2. Input ‘ssh-keygen’ and press Enter.
  3. Choose a storage location or opt for the default.
  4. Set a passphrase for enhanced security.
  5. Confirm the passphrase.
  6. Your keys are now generated and saved.

2: Using Windows Subsystem for Linux (WSL)

  1. Open the Windows Terminal or Command Prompt within WSL.
  2. Specify the algorithm (e.g., RSA-4096) by entering ‘ssh-keygen -t rsa -b 4096’.
  3. Specify the file’s location and passphrase (if needed).
  4. Confirm the passphrase.
  5. Your keys are generated and stored.

NOTE: You will need the Windows Subsystem for Linux (WSL) on your Windows 10 PC. You can download it from the Microsoft Store.

3: Using PuTTY

  1. Download and set up the PuTTY client.
  2. Launch PuTTYgen.
  3. Select the SSH key type and configure parameters (e.g., RSA-4096).
  4. Generate the keys.
  5. Set and confirm a passphrase.
  6. Save both the public and private keys.

Why Multiple Keys Are Valuable

If you interact with various servers, generating multiple keys is a breeze. Repeat the process, label files appropriately, and avoid confusion. Remember to transfer keys when switching PCs to retain access.

Securing your connections need not be complex. With these straightforward methods, crafting SSH keys on Windows becomes a seamless process. Whether you favor the native Command Prompt, the Linux-friendly WSL, or the reliable PuTTY, safeguard your keys and enjoy secure remote access. Keep your passphrases secure, and you’re ready to navigate the digital landscape with confidence.
