# Transposition
## Challenge: We intercepted this secret message. We believe it is using a transposition cipher. Can you decipher it?

```

By organizing each block of characters on top of another, we get:

```
C i t g o e 6 b 0
o o h e r n 6 3 6
n n i . t g 1 e 2
g s s T h e 5 8 e
r s c h i i 3 6 6
a o h e s s 3 a e
t l a f c f 3 d c
u v l l h l 2 4 f
l i l a a a 7 3 0
a n e g l g 5 0 6
t g n f l { 3 3 }
```

And by reading it column by column, we get `flag{66153332753b3e86ad4303062e6ecf06}`
