How to generate an SSH key pair in Windows using PuTTY?

You can generate an SSH key on Windows using the PuTTY SSH client. You can download PuTTY for free from this URL.

To generate a key with PuTTY, you should:

• Download and start the puttygen.exe generator.
• In the “Parameters” choose SSH2 DSA and press Generate.
• Move your mouse randomly on the small screen to generate the key pairs.
• Enter a key comment, which will identify the key (useful when you use several SSH keys).
• Type in the passphrase and confirm it. The passphrase is used to protect your key. You will be asked for it when you connect via SSH.
• Click “Save private key” to save your private key.
• Click “Save public key” to save your public key.
