Rot-13 stands for rotate 13 and is a Caesar cipher (a code were each letter is replaced with another eg a=c b=d c =f etc.) where you replace each letter with the one 13 letters after it ,so a=n .Because there are 26 letters in the alphabet and it rotates 13 you can use the same program to encode and decode it.
