# Blind Date (573 Points)
My mom got me a date with someone! she sent me an image but i cannot open it. I don't want it to be a blind date. Can you help me?
and a jpeg file (xyz.jpg)
Checking the hex of xyz.jpg showed that every 4 bytes were reversed
Running strings on this image gave Base64 encoded string:
g4iLuACIuACIgAiLg4iLuACIuACIgAiLg4iLuACIuACIgAiLgAiLN4iLg4iCgACIgAiLg4CIgACIgACIgAiLgACIg4CIgACIgAiLg4CIg4CIK0AIgACIu4CIgACIgACIgACIu4CIgACIgACIgAiLu4CIgACIgACIgAiLKPgL
which on decoding gave a braille text
``` .. . .. .. . .. .. . .. . ..
. . . . . . . .
.. .. . .. . .
```
Which translated to F4C3P4LM (will be used to later)
The header should have ffd8ffe0 instead of e0ffd8ff
Using blind.py, the bits were reversed which gave the image
using Binwalk, a hidden zip file(96DA.zip) was extracted, which was opened with 7z with the password F4C3P4LM
and it gave us flag.txt
Flag.txt had brainfuck code
```
++++++++++[>+>+++>+++++++>++++++++++<<<<-]>>>>++++++++++.+.+++++++++.<---.+++++++++++++++++.--------------.>+++.<+++++++++++++++++.<++++++++++++++++++.>>------.---------.--------.-----.++++++++++++++++++++++++++.<<.>>----.<++++++++.+++.>---------.<<+.>>++.<++.-----.+++++.<+++.>>++++++.<<-.>-----.<+.>.+++.>--------.<<---.>>++.<++.-----.+++++.<+++.>>++++++.<<-.++++++++++++.>>+++++++++.<<<++++++++++++++++++++++.
```
Decoding the brainfuck code
gave us the Flag:noxCTF{W0uld_y0u_bl1nd_d4t3_4_bl1nd_d4t3?}
