Because i was told so, cause the subject change so it cant be under there anymore.

This is the code i came up with:
from teisendaja import *
from operator import *
import binascii

teisendus = teisendus()
kood = input("Kood: ")
key = input("Võti: ")

chunksize = 2
vastus = [teisendus.teisendus3(16,2,kood[i: (i + chunksize)]) for i in range(0, len(kood),chunksize)]
vastus = ["0"*(8-len(x)) + x for x in vastus]
#key = teisendus.teisendus3(10,2,int(key))
getBin = lambda x, n: x >= 0 and str(bin(x))[2:].zfill(n) or "-" + str(bin(x))[3:].zfill(n)


def dekrüpteeria(vastus, key):
    XOR = []
    tulemus = []
    for i in range(len(vastus)):
        for j in range(8):
            XOR.append(str(ixor(int(vastus[i][j]), int(key[j]))))
        tulemus.append("".join(XOR))
        key = "".join(XOR)
        XOR = []
    return tulemus

tulemus2= []
if key == "":
    for i in range(256):
        võti = getBin(i,8)
        tulemus = [teisendus.teisendus3(2,16,i) for i in dekrüpteeria(vastus, võti)]
        tulemus = ["0"*(2-len(x)) + x for x in tulemus]
       # for j in range(len(tulemus)):
        tulemus2.append(binascii.unhexlify("".join(tulemus)))
        print("Key-" + str(võti) + ": " + str(tulemus2))
        tulemus2 = []
#tulemus = [teisendus.teisendus3(2,16,i) for i in dekrüpteeria(vastus, key)]
#print(":".join(tulemus))

#751a6f1d3d5c3241365321016c05620a7e5e34413246660461412e5a2e412c49254a24

Although this is quite ugly atm. But it serves me well, until i reach the unhexlify part. The number and lette r string at the wery end is the mesage im trying to decypher.
