🎮 Usage

Quick Start

python dog-zip-cracker.py

Step-by-Step

[?] Enter ZIP file path:
  └─ Path: /path/to/encrypted.zip        ← Enter your ZIP file path

[?] Character Set Configuration:
  ├─ Numbers (0-9)      [y/n]: y          ← Include digits?
  ├─ Uppercase (A-Z)    [y/n]: y          ← Include uppercase?
  ├─ Lowercase (a-z)    [y/n]: y          ← Include lowercase?
  └─ Symbols (!@#$...)  [y/n]: n          ← Include symbols?

[?] Password Length Range (start:end, 0:0=unlimited):
  └─ Range: 1:8                           ← Min:Max length (0:0 = unlimited)

[?] Start cracking? [y/n]: y

Password Length Range Examples

Input	Meaning
1:4	Try passwords from length 1 to 4 (a, b, ..., zzzz)
4:8	Try passwords from length 4 to 8 only
6:6	Try only 6-character passwords
0:0	Unlimited — starts at 1 and goes forever

⚙️ How It Works

Engine Selection (Automatic)

AES Encrypted ZIP
     │
     ▼
┌─────────────────┐
│ Extract AES hash │ ──→ Salt + PasswordVerify + HMAC
│ from ZIP header  │
└────────┬────────┘
         │
         ▼
┌─────────────────────────────┐
│ PBKDF2-FAST Engine          │
│ hashlib.pbkdf2_hmac (C)     │
│ + ThreadPoolExecutor (80%)  │
│ ~2,000-4,000 passwords/sec  │
└─────────────────────────────┘

ZipCrypto Encrypted ZIP

     ▼
┌─────────────────┐
│ 7z subprocess    │ ──→ CRC32 validation
│ (fallback)       │
└─────────────────┘

Password Verification Flow (AES)

1. PBKDF2-HMAC-SHA1 derives key material from password + salt (1000 iterations)
2. 2-byte verification — instantly rejects 99.998% of wrong passwords
3. HMAC-SHA1-80 — confirms the remaining candidates with full authentication
4. Zero false positives — cryptographically guaranteed

Thermal Protection

• Checks CPU temperature every 5 seconds
• Linux/Termux: reads /sys/class/thermal/thermal_zone*/temp
• Windows/Mac: uses psutil.sensors_temperatures() if available
• Pauses cracking when temperature exceeds 80°C
• Auto-resumes when cooled down

🔧 Troubleshooting

❌ "This ZIP file is NOT password protected!"

The ZIP file doesn't have encryption enabled. Make sure the file was created with password protection (AES or ZipCrypto).

❌ Engine shows "7z" instead of "PBKDF2-FAST"

The AES hash extraction failed. This can happen with unusual ZIP formats. The 7z engine is slower but still works correctly.

❌ UnicodeEncodeError on Windows

Run with UTF-8 encoding:

set PYTHONIOENCODING=utf-8
python dog-zip-cracker.py

Or use Windows Terminal instead of CMD.

❌ Slow speed (< 100/sec)

• Make sure the engine is PBKDF2-FAST (not 7z)
• Check CPU usage — thermal throttle may be active
• Close other CPU-intensive programs

📊 Performance Benchmarks

Engine	Speed	Accuracy	Notes
PBKDF2-FAST (12 cores)	~3,000/sec	100% ✅	In-memory, multi-threaded
PBKDF2-FAST (4 cores)	~1,200/sec	100% ✅	Laptop/low-end
7z subprocess	~2-5/sec	100% ✅	Fallback, very slow
Python zipfile	~50-100/sec	⚠️	ZipCrypto only

Note: AES-256 uses PBKDF2 with 1000 iterations per password, which is intentionally slow by design. For faster cracking of known hash types, consider tools like hashcat or john.
