Random Encoder 2

Okay, I made the encoder more random now. Good luck!

We are given the following script to reverse

import random as r
r.seed("try_this_lol_1234567890!@#$%^&*()qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM")

flag = "GCTF24{FLAG_REMOVED}"

encoded = ""
for i in flag:
    a = i.swapcase() if r.randint(1, 2) == 1 else i
    b = chr(ord(a) + r.randint(500, 600))
    encoded += b.swapcase() if r.randint(1, 2) == 1 else b
print(encoded) # Flag is ʘⱮˌɳɸȾɅȷⱤɽɉʍɿɅɚɚɳɰʱɚɤⱯʀꞮ˃ⱥɸɝʢɬʴʪȱʡȨʛʋɅʔɰƩʚ

First, lets try to understand this script.

Key Components

• Fixed seed

• The character is swapped to uppercase or lowercase based on a random choice

  a = i.swapcase() if r.randint(1, 2) == 1 else i

• Offset by Random Large Value

  b = chr(ord(a) + r.randint(500, 600))

• Swapcase Again

  encoded += b.swapcase() if r.randint(1, 2) == 1 else b

After reversing it, we get the following script

import random as r

r.seed("try_this_lol_1234567890!@#$%^&*()qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM")
encoded = "ʘⱮˌɳɸȾɅȷⱤɽɉʍɿɅɚɚɳɰʱɚɤⱯʀꞮ˃ⱥɸɝʢɬʴʪȱʡȨʛʋɅʔɰƩʚ"

decoded = ""
for char in encoded:
    swap_case_random = r.randint(1, 2)
    add_random = r.randint(500, 600)
    swap_case_final = r.randint(1, 2)
    
    if swap_case_final == 1:
        char = char.swapcase()
    original_ord = ord(char) - add_random
    original_char = chr(original_ord)
    if swap_case_random == 1:
        original_char = original_char.swapcase()
    
    decoded += original_char

print(decoded)

#Produces GCTF24{0rD3R_m47TEr$_!n_r@NDoM_f1x3D_5E3d}

Thus the flag is GCTF24{0rD3R_m47TEr$_!n_r@NDoM_f1x3D_5E3d}
