If I'm using the PuTTY key generator to create a public/private key pair, there is a button to "Save public key" like so:

Highlighted button in the PuTTY Key Generator window

However OpenSSH doesn't accept the format of this public key file, at least as far as I can tell. The generated public key looks like this:

---- BEGIN SSH2 PUBLIC KEY ----

---- END SSH2 PUBLIC KEY ----

(Key is not an actual public key)

Where is this key used typically? Does it work with OpenSSH at all?
