Looking at the code, we can see it uses `random.randint`

to generate the one time pad.

The thing that is most of note is that it seeds python's random generator using the current time.

Not only this, it prints out the first 10 random numbers outputted by the generator by doing `random.randint(5, 10000)`

and printing the output 10 times.

We can record the time shortly after we connect to the server.

Chances are, we won't have the exact right value.

However, we can use the 10 random numbers as a form of "check" - essentially, we can bruteforce the time based seed within a sensible range, test the seed against the 10 random numbers we know come from the generator, and find the correct one.

Once we find the correct one, it's trivial to generate the byte array and XOR back to get the flag.

script below:

Flag: rgbCTF{random_is_not_secure}

```

os.environ['TERM'] = 'linux'
os.environ['TERMINFO'] = '/etc/terminfo'
from pwn import *

from time import time
def getnums(secs):

p = remote('167.172.123.213', 12345)
recorded = int(time())
p.recvline()
nums = [int(x) for x in p.recvlines(10)]
p.recvuntil(b"Here's another number I found: ")
enc = int(p.recvline())
knownseed = None
for possible in range(recorded-100,recorded+100):
nums2 = getnums(possible)
if nums == nums2:
knownseed = possible
break
seed(knownseed)
for _ in range(10):
print(w(5, 10000))
b = bytearray([w(0, 255) for _ in range(40)])
enc = enc.to_bytes(255,'little')
print(enc)
flag = bytearray([l ^ p for l, p in zip(enc, b)])
print(flag)
```

im aware there is a module for this but: 1. idk how to use it 2. i dont want my effort to go to waste (since i made my own cube manipulator) 3. i dont like installing one time modules cus they clog up space

since it was just cbc i just had to map it to a cube and reverse the scramble then xorred it to get a pdf file

i spent too long fixing bugs with the xor process and how bytes are handled i also spent too long fixing bugs of my cube program

found a qr code in pdf and...

Let's break down the encryption step by step.

It splits the plaintext into padded blocks of 8. It also expands the key using a key expansion function so that the key is as long as the amount of blocks. The key expansion function causes a drastic loss in size of the keyspace by using modular exponentiation that is not with primitive roots and is modulus a composite(256), which would allow for more optimised bruteforce, but I didn't use this in the end. For each block, it goes through 8 rounds. In each round: 1. Take the current ciphertext. Put it through the sbox(basically a substitution table) 2. Then, put it through the pbox, essentially shuffling the binary based on a pre-determined pbox of indexes. 3. Xor every byte of the current block with the current byte of the expanded key

The sbox and the pbox are things we can easily invert. The only real "encryption" step is the xor bit.

The problem is that unlike normal AES where the key is expanded into 11 keys of the same length of the blocks, in here the key is expanded into essentially 1 byte keys. For each block, for each round, it will keep XORing with the same current byte of the key.

Essentially, we can bruteforce each byte of the key until we get printable values, as the encryption reduces the key in each block to one byte, and this one byte can be bruteforced.

I wrote inversion functions to handle the sbox and pbox, then simply bruted the one byte expanded key of each block until I got a printable value. We can concatenate the decrypted blocks to get the flag,

Flag: rgbCTF{brut3_f0rc3_is_4LW4YS_th3_4nsw3r(but_with_0ptimiz4ti0ns)}

As the title suggested, I grabbed my Jisho (jisho.org) and pasted the first "word" in.

In the side panel I saw 20-8-5 for the stroke numbers, which I immidiately recognised as A1Z26 cipher for 'THE'.

The characters were encoded into kanji with an equivalent stroke number.

I continued manual decryption until I identified the plaintext as http://www.gutenberg.org/files/45723/45723-h/45723-h.htm .

At this point I wrote a quick script to match kanji to letters 1:1 in one paragraph, and use replace on the whole text.

This was much faster, and once I had decrypted 10 or so paragraphs like this grepping for `rgb`

yielded the encrypted flag - `璧技丩忄鰏叒讞鸞鸚鱺鑱磒夢洶飳勊淩鼱殆鸝钁厵鬱`

. However, some kanji had values above 26.

I struggled with this for a while before trying to just extend them on the ASCII table, which worked!

Flag: rgbctf{~|~yominikui~|~} (meaning: illegible)

Each line has two numbers. I guessed that the numbers were encoding

line of play, character of line

So, just write a script to parse the data, then grab the appropriate lines and characters, then concatenate to get the flag.
