📚 RATE LIMITER NEDİR?
========================
Rate limiting (hız sınırlama), bir sisteme yapılabilecek istek sayısını
belirli bir zaman aralığında sınırlayan bir güvenlik mekanizmasıdır.
🎯 AMAÇLARI:
1. Brute-force saldırılarını önlemek
2. DDoS saldırılarına karşı koruma
3. Sunucu kaynaklarını korumak
4. API kötüye kullanımını engellemek
🔧 NASIL ÇALIŞIR?
• Her IP adresi için istek sayısı takip edilir
• Belirlenen süre (window) içinde max istek sayısı aşılırsa
• Yeni istekler engellenir veya geciktirilir
⚙️ YAYGIN AYARLAR:
• 5 istek / 60 saniye (Login sayfaları)
• 100 istek / dakika (API endpoint'leri)
• 1000 istek / saat (Genel kullanım)
🛡️ GÜVENLİK FAYDALARI:
1. Parola tahmin saldırılarını zorlaştırır
2. Otomatik botları engeller
3. Hesap ele geçirme saldırılarını önler
4. Sunucu yükünü dengeler
🔗 GERÇEK DÜNYA ÖRNEKLERİ:
• Bankacılık uygulamaları (3 deneme → hesap kilitlenmesi)
• E-posta servisleri (rate limiting + CAPTCHA)
• API servisleri (tier-based rate limiting)
💡 TAVSİYELER:
1. Login sayfalarında mutlaka rate limiting kullanın
2. IP tabanlı + kullanıcı tabanlı kombinasyon yapın
3. Başarısız denemeleri loglayın
4. Şüpheli aktivitelerde alarm üretin

🔐 MEMORY-HARD HASH:
Memory-hard hash fonksiyonları, özellikle paralel donanım
saldırılarına (GPU/ASIC) karşı koruma sağlamak için tasarlanmıştır.
🎯 TEMEL ÖZELLİKLER:
1. Büyük bellek gerektirir (8MB+)
2. Bellek erişimi sıralıdır, paralelleştirilemez
3. Her hash hesaplama için yüksek bellek kullanımı
🛡️ NEDEN ÖNEMLİ?
• GPU'lar saniyede milyarlarca hash hesaplayabilir
• ASIC'ler hash hesaplamayı 1000x hızlandırabilir
• Memory-hard hash'ler bu saldırıları ekonomik olarak
pratik olmaktan çıkarır
✅ KULLANIM ALANLARI:
• Parola depolama
• Kriptografik anahtar türetme
• Kritik kimlik doğrulama
⚠️ DİKKAT:
KHA-256'da sadece "TrueMemoryHardHasher" gerçek memory-hard'tır!
Diğer hash fonksiyonları (FortifiedKhaHash256, OptimizedKhaHash256)
memory-hard DEĞİLDİR!
🔧 DOĞRU KULLANIM:
```
from kha256 import TrueMemoryHardHasher
hasher = TrueMemoryHardHasher(
memory_cost_kb_kb=8192, # 8MB
time_cost=3 # 3 tur
)
hash_result = hasher.hash(password.encode(), salt)
```
💰 EKONOMİK ANALİZ:
• Memory-hard hash: ~580ms/hash
• Normal hash: ~0.001ms/hash (GPU ile)
• Yavaşlık faktörü: ~580,000x
Bu da bir saldırganın maliyetini 580,000 kat artırır!
