Before typing or pasting your own text into the box, or pushing the button, see if you can guess what is already there. Its definitely something you have seen before, and you won't need your spectacles to read it [;-) You can copy from, paste into, or just type text in the box. Since Rot-13 is its own inverse, repeatedly pushing the "Rot-13" button will toggle the text between plaintext and ciphertext.
Rot-13 gets its name from the fact that it ROTates (shifts) all of the letters of the alphabet by 13 positions. A becomes N, B becomes O ... M becomes Z, N becomes A, etc. etc. Since the 13-position rotation is half the number of letters in the alphabet, coding the same thing twice (or any even number of times) gives you back what you started with, and the code is its own inverse. Upper and lower-case letters are handled separately, so letter case is not affected, and neither are characters other than letters.
Obviously, the logic of Rot-13 applies only to US-ASCII type text. If you are using Unicode characters from another language (e.g. Chinese, Korean, Arabic), the text will be unaffected. Note, however, that US-ASCII is a strict subset (characters 0 through 127) of Unicode, so any part of your text that is in US-ASCII will be transformed by Rot-13, even if the rest of it is in another character set.
My only reward for writing this is the 15 milliseconds of fame I receive from having my name here. Don't deprive me of that.
