```
Challenge: Cryptography is the art of hiding things. there are multiple ways to do it. There are multiple layers to this message. When you find the answer then make it a flag.. mihi nomen latine! Example: flag{WORDS_WORDS_WORDS}

Here's the given jpeg file

Looks like stego challenge in there

Then I tried steghide.
Password should be "neverlan" but it didnt work then tried "neverlanctf" so it worked and extracted WhyS0CuR1o5.txt

in WhyS0CuR1o5.txt looks like base64, I decoded output is some binary values again, I tried binary to ascii, heres the some ciphertext and I tried caesar bruteforced it worked.

EXPERIENCE IS THE TEACHER OF ALL THINGS

I searched this words in google and its Caesar Words

Original full name Gaius Julius Caesar
![](https://raw.githubusercontent.com/ozancetin/CTF-Writeups/master/2018/NeverLAN%20CTF%202018/How%20much%20can%20you%20throw%20on%20a%20Caesar%20salad%3F/6.png)

When I found this, tried almost all combinations
like
```
flag{Gaius_Juluis_Caesar}
flag{Juluis_Caesar_Gaius}
flag{Caesar_Gaius_Julius}
```
But these didnt work

After then research in google about Caesar I found his latin script

CAIVS IVLIVS CAESAR
so flag must be:

```
flag{CAIVS_IVLIVS_CAESAR}
```
