To convert your private key
- Start PuTTYgen (for example, from the Start menu, choose All Programs > PuTTY > PuTTYgen).
- Under Type of key to generate, choose RSA.
If you’re using an older version of PuTTYgen, choose SSH-2 RSA.
- Choose Load. By default, PuTTYgen displays only files with the extension
.ppk. To locate your
.pemfile, select the option to display files of all types.
- Select your
.pemfile for the key pair that you specified when you launched your instance, and then choose Open. Choose OK to dismiss the confirmation dialog box.
- Choose Save private key to save the key in the format that PuTTY can use. PuTTYgen displays a warning about saving the key without a passphrase. Choose Yes.

- Specify the same name for the key that you used for the key pair (for example,
my-key-pair). PuTTY automatically adds the
Your private key is now in the correct format for use with PuTTY. You can now connect to your instance using PuTTY’s SSH client.
