Brute Force in python [closed]

2024/10/5 21:22:01

I am trying loop the decrypted message 10 times, but I am getting very different results, I don't know why. Below is my code. I have used the same code for encrypting and decrypting. I only had to change the newchar = newchar-shfit. Using the same code for looping gets me very different results.

  num1=0shift=0print("Brute force")question=input(print("Please enter something to decrypt: "))decryptedword = ""while num1<10 and shift <10 :for character in question:newchar = ord(character)newchar = newchar - shiftif newchar < 32:newchar = newchar + 95elif newchar > 126:newchar = newchar - 95decryptedword = decryptedword + chr(newchar)print(num1,"decrypted word: ",decryptedword)num1=num1+1shift=shift+1

For example if type in asdasd in the input, I get:

1 decrypted word: a

2 decrypted word: ar

3 decrypted word: arb

4 decrypted word: arb^

5 decrypted word: arb^o

6 decrypted word: arb^o_

OK, sample output on how it should be, if I input dvg, I should get:

1 decrypted word:fxi

2 decrytped word:asd

3 decrypted word:ewh

and so on..

Answer

Well you are increasing the shift value with every loop iteration, and therefore altering your key with each iteration. And since you are incrementing your key (shift) with every iteration your decrypted result is also different in each iteration.

If you remove this line shift=shift+1 the decrypted message should be the same with every iteration.
(EDIT3: I do not know how to 'strike through' text, but the above lines should be ignored, as I had misunderstood the authors problem.)

EDIT: And another note, your indentation seems to be wrong. The if ; elif statement is indented as if they are NOT part of the loop, which also causes unexpected behavior.
EDIT2: Furthermore decryptedword = "" Should be inside the loop so it gets reset with every iteration.

   num1=0shift=0print("Brute force")question=input(print("Please enter something to decrypt: "))while num1<10 and shift <10 :decryptedword = ""for character in question:newchar = ord(character)newchar = newchar - shiftif newchar < 32:newchar = newchar + 95elif newchar > 126:newchar = newchar - 95decryptedword = decryptedword + chr(newchar)print(num1,"decrypted word: ",decryptedword)num1=num1+1shift=shift+1
