4. You are prompted to enter a name (for example, sshkey.pub) and a location for the public 
key (for example, C:\Keys\). Enter this information and click Save.
Ensure that you record the SSH public key name and location because this information 
must be specified later. 
5. Click Save private key. A warning message is displayed (see Figure B-4). Click Yes to 
save the private key without a passphrase.
Figure B-4   Confirm the security warning
6. When prompted, enter a name (for example, sshkey.ppk), select a secure place as the 
location, and click Save.
7. Close the PuTTY key generator.
Public key extension: By default, the PuTTY key generator saves the public key with 
no extension. Use the string pub for naming the public key. For example, add the 
extension .pub to the name of the file to easily differentiate the SSH public key from the 
SSH private key.
Note: It is possible to use a passphrase for an SSH key. Although this action increases 
security, it generates an extra step to log in with the SSH key because it requires the 
passphrase input.
Key generator: The PuTTY key generator saves the PuTTY private key (PPK) with the 
.ppk extension.
