anyone knows on how to setup / enter public key into mystic so I won't need to authorize by password when accessing via ssh?
AFAIK it doesn't have that function and just uses SSH for link encryption.
Even password authentication over SSH is optional since you can enter invalid credentials and it'll just bring you to the BBS login prompt.
