Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

This is the program we believe was used to encode the intercepted message.

some of the retrieved program was damaged (show as &&&&)

Can you use this to figure out how it was encoded and decode it?

Good Luck

import string
import random
from base64 import b64encode, b64decode

secret = '&&&&&&&&&&&&&&' # We don't know the original message or length

secret_encoding = ['step1', 'step2', 'step3']

def step1(s):
_step1 = string.maketrans("zyxwvutsrqponZYXWVUTSRQPONmlkjihgfedcbaMLKJIHGFEDCBA","mlkjihgfedcbaMLKJIHGFEDCBAzyxwvutsrqpo")
return string.translate(s, _step1)

def step2(s): return b64encode(s)

def step3(plaintext, shift=4):
loweralpha = string.ascii_lowercase
shifted_string = loweralpha[shift:] + loweralpha[:shift]
converted = string.maketrans(loweralpha, shifted_string)
return plaintext.translate(converted)

def make_secret(plain, count):
a = '2{}'.format(b64encode(plain))
for count in range(count):
r = random.choice(secret_encoding)
si = secret_encoding.index(r) + 1
_a = globals()r
a = '{}{}'.format(si, _a)
return a

if name == 'main':

print make_secret(secret, count=&&&)

this is the code

Formatting code on Discord

Here's how to format Python code on Discord:

```py
print('Hello world!')
```

These are backticks, not quotes. Check this out if you can't find the backtick key.

For long code samples, you can use our pastebin.

[waxen harness]

yeah i did that but im still getting errors i changed some code soo far

[empty zephyr]

describe your error.

[waxen harness]

thanks you the error i am getting is this now

[empty zephyr]

so I suppose the code in this snip is something that makes a secret

and now, you have to work backwards, right?

[waxen harness]

yes but im getting a bit confused on what to change it in too

[empty zephyr]

so start by understanding all the steps

make a reversed version of them

[waxen harness]

so like going backwards

[empty zephyr]

yes

if there's a function that makes A -> B, make something that takes the B and makes it A. B -> A

[waxen harness]

and also is it better to do it on pycharm then put it in kali linux after

[empty zephyr]

not really

but, it depends on your skill

it's more about the logic

[waxen harness]

ohhh okay so its better for me to stay in kali linux and do it

[empty zephyr]

its fine focus on the logic 😭

[waxen harness]

yeah sorry im a lil bit slow just tryna decode this message 😢

so i need to reverse the logic

[empty zephyr]

yes

and check if you can actually reverse the logoc

[empty zephyr]

I see a random.choice but random is not seeded

so you won't be able to reverse it

[waxen harness]

ohh okay so i cant reverse random.choise but i can reverse the other stuff

[empty zephyr]

it will be a blocker

[waxen harness]

ohh so what does this mean i wont be able to reverse it now do i got ot remove reverse.random

[empty zephyr]

do you have the encoded string with you

[waxen harness]

yes i do i will share

[empty zephyr]

is it a part of the question

[waxen harness]

yes it is

[empty zephyr]

or you were allowed to make it too

can you post the code again?

!paste

Pasting large amounts of code

If your code is too long to fit in a codeblock in Discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the Paste! button in the bottom left, or by pressing CTRL + S. After doing that, you will be navigated to the new paste's page. Copy the URL and post it here so others can see it.

[empty zephyr]

use the above link

just post the code

i feel im missing something

just wanna cross check if the random is seeded

[waxen harness]

https://paste.pythondiscord.com/DIZQ

[empty zephyr]

not the string 😢 i meant the code

[waxen harness]

oh sorry il send

https://paste.pythondiscord.com/APWQ

[empty zephyr]

random is not seeded

you can run a small example program:

import random
a = [1, 2, 3]
print(random.choice(a))

to get a different number on each run

[waxen harness]

yeah i ran a small program

[waxen harness]

what does this mean

does

this mena i cna

reverse it

[empty zephyr]

no you can't

[waxen harness]

damn so what do i do now to be able to use this as a decoded

[waxen harness]

hello is there anything i can try do to use this as a decoder

[empty zephyr]

idts

you might call smone else here

[waxen harness]

how do i it is it /help

or

[empty zephyr]

post the channel name in #python-discussion

[waxen harness]

so i am trying to solve this code to try and decode the message and i am stuck please help

[waxen harness]

i posted in discussion and i didnt get a reply

[empty zephyr]

it's fine, consult your professor

to seed the random generator

[waxen harness]

didnt he not give it to us in thi s
