MD5 Cracking — Rainbow Table Yechimi

Masala tahlili

MD5 hash cracking. Berilgan: 5f4dcc3b5aa765d61d8327deb882cf99

Fikrlash jarayoni

MD5 bir tomonlama funksiya — to'g'ridan to'g'ri decrypt bo'lmaydi.

Lekin oddiy so'zlar uchun rainbow table ishlaydi.

Yechim usullari

1. Online Rainbow Table

CrackStation.net saytiga kirib hash ni joylashtiring:

5f4dcc3b5aa765d61d8327deb882cf99

Natija: password

2. Python bilan wordlist

import hashlib

target = "5f4dcc3b5aa765d61d8327deb882cf99"

# Kichik wordlist
words = ["password", "123456", "qwerty", "admin",
         "letmein", "welcome", "monkey", "dragon"]

for word in words:
    h = hashlib.md5(word.encode()).hexdigest()
    if h == target:
        print(f"Topildi: {word}")
        break

3. Hashcat bilan

echo "5f4dcc3b5aa765d61d8327deb882cf99" > hash.txt
hashcat -m 0 -a 0 hash.txt /usr/share/wordlists/rockyou.txt

Python script

#!/usr/bin/env python3
import hashlib

target_hash = "5f4dcc3b5aa765d61d8327deb882cf99"
password = "password"

verified = hashlib.md5(password.encode()).hexdigest() == target_hash
print(f"Parol: {password}")
print(f"Tasdiq: {verified}")
print(f"Flag: NULL{{{password}}}")

Yakuniy flag

NULL{password}

Muhim eslatma

MD5 parol saqlash uchun ishlatilmasligi kerak! Bugungi kunda bcrypt, Argon2 yoki scrypt ishlatiladi.
