# CTF Challenge Writeup: Nintendo Base64
## Challenge Information
- Name: Nintendo Base64- Category: Crypto
## Challenge Analysis
The challenge was fairly easy, a file is given with Base64 encoded data. The goal was to find the flag.
## Solution
### Step 1: Analysing and decoding the data
Nintendo has used multiple Base64 encoding functions in a row to 'encrypt/obfuscate' data in the past. The data in this challenge looks exactly the same, and by removing the new lines and decoding it multiple times we get the flag!![img/NintendoBase64-1.png](img/NintendoBase64-1.png)
## Flag
`CHTB{3nc0ding_n0t_3qu4l_t0_3ncrypt10n}`
## Conclusion
Encoding/obfuscation != Encryption
