note ww Historians sometimes assert that any "encoding system" using a fixed value for the change in positions in the alphabet is a (n example of a) Ceasar Cipher -- ie, if the value for the change is +3, A (in position 1) becomes D (position 4). 13 is the oft-cited value. <p>In the computer world, it's often called ROT13 for rotate 13 positions. [moritz]' example above provides an example.</p> <p>I don't know about a "<i>10 shift to the right</i>" -- certainly, as indicated in para 1, that would be a valid way to implementing a Ceasar Cipher... and so would a <i>10 shift to the left</i> but (IMO) both would make it easier to err if "encoding" manually.</p> <!-- Node text goes above.
