We wrote a simple script that gave the flag.
```
import base64
# string from the NOTflag.txt
encoded_str = "nZyenIuZhMiXtoygzoygyJfMoJmTnsaC"
decoded_bytes = base64.b64decode(encoded_str)
def xor_characters(s, key):
return ''.join(chr(ord(char) ^ key) for char in s)
for key in range(256):
xored = xor_characters(decoded_bytes.decode('latin1'), key)
if "bcactf{" in xored:
print(f"XOR {key}: {xored}")
```
Flag: `bcactf{7hIs_1s_7h3_fla9}`
