Hi all,

I wonder if anyone could guide me; I am new in cipher text and C++.

My question is: If I've been given a cipher text (random e.g: xfmmepofzpvibwfdsbdl) - This cipher text was created by first exchanging all occurrences of x and e in the plaintext and then applying a Caesar cipher.

Can anyone tell me - How I can approach this example ?

Many thanks,
TMiB

Here is a link to cipher frequency analysis which can be used as a starting point for deciphering the caesar text.
