dsa - an previous US authorities Digital Signature Algorithm. createssh It is based on the difficulty of computing discrete logarithms. A key size of 1024 would normally be used with it. DSA in its original form is no longer recommended.

You could dismiss the "randomart" that is definitely shown. Some distant desktops could teach you their random artwork each time you connect.
