Convert the Private Key to the PPK Format
The private key created by Amazon uses the industry standard PEM format. To connect to Gateway appliance using PuTTY or any other program that uses a different private key format, you need to convert the key pair into that application’s native format. Consult the documentation for your SSH program if you are unsure of its support for private key formats.
The following steps describe how to convert the key file using PuTTY. For other programs, please consult the user documentation accompanying the program.
  1. Download and run 
    puttygen.exe
    This opens the PuTTY Key Generator.
  2. From the PuTTY Key Generator menu, select 
    Conversions
     > 
    Import Key
    . Select the key pair PEM file created previously.
  3. Click 
    Save private key
     in the PuTTY Key Generator dialog. 
    A warning about saving the key without a passphrase appears. Creating a passphrase is optional.
