Hi

Is it possible to import rsa private key into putty?

If you created your rsa identity with openssh's ssh-keygen, you can use it with putty. If you have Pageant running and copied the _private_ key to your machine with putty, just select "Add Key" and select the private key file.

Putty doesn't use the public identity part.

I've created public key using:on the linux machine.
Howto import it to putty and which extension should have a public key file?

if you didn't use "ssh-keygen -t rsa -f my_key", then the two files you get are called:

identity
identity.pub

identity is the private key, identity.pub is the public part.

Copy those files to the machine you run putty on- you can put them anywhere.

Then create a new Putty sessions, and in the options panel, go to Category -> SSH -> Auth and in the box that says "Private key file for authentication", select the "identity" file.

identity.pub contains the public key half that you add to your .ssh/authorized_keys file

hope that helps!

You can also use the Pageant program that is included with putty. Load the "identity" file, and make sure that in SSH -> Auth you have the "Attempt Authentication using Pageant" box checked.

good luck!

Thx, I've done how u suggested, but I'm gtting this problem:

Unable to use key file "C:\Support\id_rsa" (OpenSSH SSH-2 private key)
Using username "root".

my apologies- I forgot all about that. Pageant uses a different ssh2 key format than openssh. There's a way to convert them, but its probably easier to use puttygen to generate an ssh2 key on your windows machine, and then put the contents of the .pub file into your .ssh/authorized_keys file.

If you google for openssh putty ssh2, you may be able to locate the steps to convert the key format. I know its possible but can't remember how to do it.
