        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2

This bug was originally reported as
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=492447 by Saku Ytti;
I'm just passing it on since I don't know the plans for VisualHostKey.

"It might be interesting, if VisualHostKey would use more geometrically
connecting characters. Such as, say if we printed character -, it could
be followed to the right, by only \, /, -, ., ) etc. Anything that
would make it appear as consistent picture to human eye.

Also I'd like to believe most terminals are capable of ANSI colours, so
that could add accuracy of the identification in very cheap manner, but
the colours would need to be also locked to the neighbouring colours,
so that it would produce consistent colour theme, instead of random
cacophony. Perhaps it could be -o VisualHostKey=colour."

As for the geometrically connected characters:  No, you would lose
information if you would downgrade to them.  The characters are not
there to be just eye candy, but they show you different levels of
augmentation, i.e. where the worm walked once, twice and so on.  You
can't give this up without seriously losing information.

And as for ANSI colours:  No as well.  The algorithm was designed to
work on the most primitive terminals by purpose, and I don't see that
adding colors here would be a very consistent way of design either,
regarding the whole OpenSSH project.  OpenSSH does not use colors
anywhere else for good reason, and so does the randomart algorithm.

I am afraid that at least I won't perform any of the enhancements you
proposed.
