Windows - convert a .ppk file to a .pem file
- Start PuTTYgen. For Actions, choose Load, and then navigate to your .ppk file.
- Choose the .ppk file, and then choose Open.
- (Optional) For Key passphrase, enter a passphrase. For Confirm passphrase, re-enter your passphrase.
Note: Although a passphrase isn't required, you should specify one as a security measure to protect the private key from unauthorized use. Using a passphrase makes automation difficult, because human intervention is needed to log in to an instance or to copy files to an instance. - From the menu at the top of the PuTTY Key Generator, choose Conversions, Export OpenSSH Key.
Note: If you didn't enter a passphrase, you receive a PuTTYgen warning. Choose Yes. - Name the file and add the .pem extension.
- Choose Save.
