openssh to ssh2 interoperability

I have openssh identity and identity.pub which work well on many machines to uniquely identify myself.

I want to put these on a host (Tru64) using ssh2. I can convert the public key to ssh2 format using "ssh-keygen -e" on an openssh box.

How should I convert the private key?

As far as I know "-e" flag will work for both public and private key ? Am I wrong ? At least this is what's stated in the "man ssh-keygen" :

edit : .... or maybe this won't work, does that helps ?

It may read a private key but it prints out a public key.

Good news is I've found a solution, ... do the conversion with Putty's "puttygen" . :slight_smile:
