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{…}
When we read the description clearly we can understand the Substitution/Caesar Cipher has been used to encode the string.
On comparing dixoae and inctfj , we shall find that there is a shift of 5 in the left direction. Hence the key for this cipher is 5.
Lets use a Caesar Cipher Decoder to find the flag
By using 5 as key we will be able to decode the string
The required flag is inctfj{thee_the_master_of_caeser_cipher}
