## Solution
### Encription
* **ASCII** -> **Octal Number** -> **Each Digit** -> **Emoji**
### Decryption
* **Emoji** -> **Octal Digit** -> **Octal Number** -> **Emoji**
### Script - [emojidecoder.py](emojidecoder.py)
```py
from itertools import *
cipher = "⭐?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐?⭐ ?? ⭐?? ⭐?? ⭐?? ⭐?⭐ ⭐?? ?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐?⭐ ⭐?? ⭐?? ?? ⭐?⭐ ⭐?? ?? ⭐?? ⭐?? ⭐?? ?? ⭐?? ⭐?? ⭐?? ⭐?? ?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐?⭐ ⭐?? ⭐?? ?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐?? ⭐??".split(' ')
"""
Brute-force these emojis for the correct octal code
?,?,? : (0,2,4)
"""
def breakit(emap):
flag = ''
for chunk in cipher:
octcode = ''
for emoji in chunk:
octcode += emap[emoji]
flag += chr(int(octcode, 8)) # octal code to ASCII i.e., 163 = 's'
print(flag)
def makeit():
emomap = {
'⭐' : '1',
'?' : '6',
'?' : '3',
'?' : '5',
'?' : '7'
}
# permutations of emoji and relative numbers
numperms = permutations(['0','2','4'])
emo = ['?','?','?']
for nums in numperms:
temp = {}
for i in range(len(nums)):
temp[emo[i]]=nums[i]
emomap.update(temp)
# try to break it with every possible emoji-maps
breakit(emomap)
if __name__ == '__main__':
makeit()
```
