Why ssh-keygen creates empty key files?

  • 772

I launched ssh-keygen, answered all questions and it reported that keys were successfully generated, but files are empty. Why?

~ > ssh-keygen -C "my key to github"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/zubba/.ssh/id_rsa): id_github
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in id_github.
Your public key has been saved in id_github.pub.
The key fingerprint is:
83:73:78:8b:bb:dc:bb:a8:d7:b0:b0:fa:51:30:fd:55 my key to github
The key's randomart image is:
+--[ RSA 2048]----+

|    o .   .      |
|     o + .       |
|      = S        |
|    ...= o       |
|    .o.+.        |
|    .oo+.        |

  1. You started ssh-keygen in $HOME. The files get created there:

    ls -ltr ~/id_github*

    I guess the files in .ssh/ are old ones?
