Press ENTER three times. This will

  • create a folder /.ssh for the keys as well as

  • file id_rsa for secret key and

  • file id_rsa.pub for public key.

These are the default values.

Warning

If you have created other keys in those same locations, you can define other folder and files instead of just pressing Enter three times.
