ROT13 encryption algorithm is used in Usenet newsgroups to avoid readers accidentally reading the offensive content. It is also used for encrypting solutions for quiz and puzzles. ROT13 is one of the simplest encryption algorithms and can be encrypted or decrypted by just replacing the letters.
ROT13 Algorithm: In ROT13 encryption algorithm every letter is replaced by a letter which comes after 13 places of a particular letter. For Example: a is replaced by n, b is replaced by o, c is replaced by p, and so on. Capital letter is replaced by a capital letter and small letter is replaced by a small letter.
Here is the truth table for replacements of letters in ROT13:
For Example: More Process can be encrypted by using ROT13 to: Zber Cebprff
