Generate SSH Key using PuTTYgen With PuTTYgen you can generate SSH key pairs (public and private key) that are used by PuTTY to connect to your server from a Windows client. The private key will be stored on your local machine, while the public key has to be uploaded in your dashboard. PuTTY uses a different key file format. It comes with tools to convert between its own.ppk format and the format of OpenSSH. This ssh-3.2.9.1 you found is a commercial product which has its own different private key format. There's no reason to use it instead of OpenSSH, it can only be less compatible, it requires paying, and there's about. Some SSH servers (such as ssh.com’s) require a public key in this format in order to accept authentication with the corresponding private key. (Others, such as OpenSSH, use a different format) To save your public key in the SSH-2 standard format, press the Save public key button in PuTTYgen. PuTTYgen will put up a dialog box asking you where. The author of the quoted blog post goes on to explain how OpenSSL supports the PKCS#8 format (about which I know precisely nothing), offering protection against brute-forcing encrypted private keys that have fallen into the wrong hands through key stretching (PBKDF2). However, my own valuable private keys are stored in Putty's own.PPK format.


SSH keys are a means of authenticating a user to an SSH server without using a password. Each “key” is actually a key pair consisting of a public key and a private key.

Keys are more secure than passwords because they are significantly more complex. While a password of eight characters is 72 bits long, SSH keys are often 2048 bits or longer. This longer string has many more possible permutations and therefore takes much more time to crack with a brute force attack.

If you require SSH access for multiple users, the use of SSH keys instead of individual logins can bypass many of the headaches involved in user management without violating PCI DSS. For details, see What are the advantages of using SSH keys to control access for multiple users?

Method

The process involves generating a pair of SSH key files containing a private key and a public key. The private key is known only to the user’s computer; the public key will be known to the server. Each key is useless without the other; therefore, only individuals with both the private and the public key can gain access to the server, and the private key is never revealed to the server.

Take special care to not lose the private key. A lost private key cannot be replicated; therefore, users cannot access the server until an administrator generates a new key pair. If you lose access to your server due to a lost key, contact our Support Team for assistance.

Though there are varying methods of generating SSH keys on machines using Windows, this one uses PuTTY Key Generator.

1: Generate the key

ATTENTION: The procedure and screen captures in this section reflect the latest version of PuTTY as of July 21, 2017 (0.70). If you use a different version, your interface may differ from the one pictured.

  1. Download and install PuTTY.

ATTENTION: In Step 2 below, if you are using a pre-0.70 version of PuTTY, then select SSH-2 RSA radio button instead.

  1. In the Type of key to generate section, select the RSA radio button.

  2. In the Number of bits in a generated key field, type 4096.

  3. Click Generate.

  4. Move your mouse cursor in the area below the progress bar. When the progress bar is full, PuTTY generates your key pair.

  5. (Optional) Type a passphrase in the Key passphrase field. Repeat this passphrase in the Confirm passphrase field. If you plan to use your keys for automated processes; skip this step.
  6. Click the Save private key button to save the private key in a secure location. Use any name you like.
  7. Right-click in the text field labeled Public key for pasting into OpenSSH authorized_keys file and choose Select All.
  8. Right-click again in the same text field and choose Copy.

  • Download and start the puttygen.exe generator.
  • In the 'Parameters' section choose SSH2 DSA and press Generate.
  • Move your mouse randomly in the small screen in order 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.
