rot13
8. ROT13 Encryption
Rot13 is a cipher which is based on rotation of alphabetic characters by 13. The numeric and none alphabetic characters remain unchanged. Because there is 26 letters in English alphabet rotating characters by 13 encodes and decodes the string. So in our test email first letter of our email is “n” which would become “a” since we would count 13 letters from “n” in the alphabet in circle.
