**Description:**
**Knowledge required :**
1) Base64 representation
**Solution:**1) From the bo1lers ctf we get the base64 encoded string `d2N0ZntNNDF6M180bmRfQmx1M30K`
2) Decoding it gives us the flag```echo d2N0ZntNNDF6M180bmRfQmx1M30K | base64 -d                                                                                                          wctf{M41z3_4nd_Blu3}```
