WeChall - Crypto - Caesar I

Posted on In Views: Disqus:

Challenge

A classic Caesar cipher challenge. Each visit generates a different ciphertext, but it's always ROT13 (shift of 13, since shifting 13 twice returns the original text, making it a bijection).

Example ciphertext:

1
IWT FJXRZ QGDLC UDM YJBEH DKTG IWT APON SDV DU RPTHPG PCS NDJG JCXFJT HDAJIXDC XH CETVGGCTXUAE

Solution

i use cyberchef to solve this challenge.

use ROT13_Brute_Force(true,true,false,100,0,true,'')

Amount = 11: THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG OF CAESAR AND YOUR UNIQUE SOLUTION IS NPEGRRNEIFLP
