Issue with ssh-keygen

[Kelly Dunlop]

Hi,

I am running openssh7.3p1 on an embedded Linux system and discovered this problem.

If I run:

	ssh-keygen -t rsa1 -f testfile

it appears to generate the key and I get the output:

	Generating public/private rsa1 key pair.
	Enter passphrase (empty for no passphrase): 
	Enter same passphrase again: 
	Saving key "testfile" failed: unknown or unsupported key type

Should this option be returning with a deprecated key type message ?

I can't find a bug already reported about this and I have downloaded openssh 7.4p1
and the problem exists on that too.  I have checked the archives at http://marc.info/
and there didn't appear to be anything there.

Apologies if this has apready been discussed as I am not on the mailing list.
Thanks in advance for any pointers
Kelly
