I'm trying to write some code capable of authenticating with a private key on windows.
I generate my key with no passphrase:
Generating public/private rsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_rsa): client_k
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in client_key.
Your public key has been saved in client_key.pub.
The key fingerprint is:
The key's randomart image is:
|O=* . o+. |
|X=.o . . .o. |
|+= o o . ... |
|E.o . B...+ . |
|... +.=S* o |
|.. +.+ = . |
|.. o + o |
|. . o . |
| o |
The key can be used successfully to authenticate:
c:\var\client>ssh -i client_key localhost
Last login: Thu Aug 22 16:34:22 2019
My perl code is very simple at the moment:
my %params = (
"protocol" => '2',
"use_pty" => 0,
"options" => ["stricthostkeychecking no"],
"identity_files" => ["client_key"],
"debug" => 1,
$ssh = Net::SSH::Perl->new($server, %params);
But executing it returns Wrong key type.

I've tried generating DSA type keys and the error is the same. Googling it is not helping either.
Any help appreciated!
