Here's how you can generate SSH public/private keys on Windows. You probably used PuTTY or at least heard about it. It’s an excellent utility and has been a favorite SSH client for years. In the “/.ssh/authorizedkeys” file (or rather, pasted/added to this file). To open this key, to copy, and then paste, wherever necessary. PuTTY does not natively support the private key format (.pem) generated by Amazon EC2. PuTTY has a tool named PuTTYgen, which can convert keys to the required PuTTY format (.ppk). You must convert your private key into this format (.ppk) before attempting to connect to your instance using PuTTY.
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. Openssl generate key and csr in one command. 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.

In the Type of key to generate section, select the RSA radio button.
-
In the Number of bits in a generated key field, type 4096.
-
Click Generate.
-
Move your mouse cursor in the area below the progress bar. When the progress bar is full, PuTTY generates your key pair.
- (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.
- Click the Save private key button to save the private key in a secure location. Use any name you like.
- Right-click in the text field labeled Public key for pasting into OpenSSH authorized_keys file and choose Select All.
- Right-click again in the same text field and choose Copy.
2: Upload the SSH key
