+ Introduce SSH Fingerprint ASCII Visualization, a technique inspired by the
+ graphical hash visualization schemes known as "random art", and by
+ Dan Kaminsky's musings on the subject during a BlackOp talk at the
+ 23C3 in Berlin.
+ Scientific publication (original paper):
+ "Hash Visualization: a New Technique to improve Real-World Security",
+ Perrig A. and Song D., 1999, International Workshop on Cryptographic
+ Techniques and E-Commerce (CrypTEC '99)
+ http://sparrow.ece.cmu.edu/~adrian/projects/validation/validation.pdf
+ The algorithm used here is a worm crawling over a discrete plane,
+ leaving a trace (augmenting the field) everywhere it goes.
+ Movement is taken from dgst_raw 2bit-wise. Bumping into walls
+ makes the respective movement vector be ignored for this turn,
+ thus switching to the other color of the chessboard.
+ Graphs are not unambiguous for now, because circles in graphs can be
+ walked in either direction.
