ROT13 is one of the single transliteration ciphers that encrypts by replacing the characters in the text with other characters.
Character replacement is performed by shifting the characters from "A" to "Z" by 13 characters out of the 26 characters of "ABCDEFGHIJKLMNOPQRSTUVWXYZ".
For example, "A" is encrypted to "N" and "Z" is encrypted to "M".
Plain : ABCDEFGHIJKLMNOPQRSTUVWXYZ Cipher: NOPQRSTUVWXYZABCDEFGHIJKLM
Plain text : THIS IS A SECRET MESSAGE Cipher text: GUVF VF N FRPERG ZRFFNTR
Since there is reciprocity that plaintext can be obtained by encrypting ciphertext again, decryption can be done in the same flow as encryption.
