I assume you're referring to the "Bad RSA1 key file" message?

Current versions of OpenSSH say "Not a RSA1 key file" but it's just the 
way sshd detects if a keyfile is for SSH v1 or v2: it tries loading is 
as a v1 key first (which generates that warning if it's a v2 key), and 
if that fails it tries it as a v2 key.

(See key_load_private() in authfile.c).

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
