As Piru already mentioned, MorphOS does NOT use AmiSSL. There should normally be no reason for installing it on your system.

My guess would be that you have not placed your SSH key in the right location / your HOME: is misconfigured. Make sure you have a user configured in System Preferences / Users with a correct home path. Reboot, open a shell, type 'home:' enter and see where that takes you. Put the .ssh stuff there and it should work OK.
