# Beginner: Anti-dcode.fr
> I've heard that everyone just uses dcode.fr to solve all of their crypto problems. Shameful, really. This is really just a basic Caesar cipher, with a few extra random characters on either side of the flag. Dcode can handle that, right? >:) The '{', '}', and '_' characters aren't part of the Caesar cipher, just a-z. As a reminder, all flags start with "utflag{".
Working with the file I do the following. I put the file into [CyberChef](https://gchq.github.io/CyberChef/), and do a `ROT13` and then a `Find / Replace` and check for any instances of the string `utflag{`.
I roll through the rotation till I see a length drop in the output at `18`.
I delete the `Find / Replace`, and save the output.
Searching the saved output for `utflag{` I find the flag.
Flag: `utflag{rip_dcode}`
