Cryptography is a technique of securing information and communications through use of codes so that only those person for whom the information is intended can understand it and process it.

Below, I am discussing on one of the easiest CTF crypto challenge from Traboda.com

CHALLENGE DESCRIPTION

This Cipher is a very simple and common encryption method which forms part of the basis of cryptography. It simply shifts a string of letters a certain number of positions up or down the alphabet.

encoded string: dixoae{oczz_ocz_hvnozm_ja_xvznzm_xdkczm}

Flag Format: inctfj{...}

On analyzing the the ciphertext, first thing that came to my mind was caeser cipher. Using common cipher decoder, I decrypted it. Without doing more, I got the flag!!

flag for challenge:
