KuaiYa Security Protection System

Multiple encryption technologies for comprehensive network security

🔐

AES-256 Encryption

KuaiYa uses AES-256 encryption, the same standard used by NSA for classified information and banks worldwide. No known破解 methods exist.

🛡️

Multi-Protocol Support

KuaiYa supports OpenVPN, WireGuard, IKEv2/IPSec, L2TP/IPSec. WireGuard is faster with less code; OpenVPN is proven stable.

🔒

RSA-4096 Key Exchange

KuaiYa uses RSA-4096 for initial handshake. Each session generates unique forward-secrecy keys - even if long-term keys leak, past sessions remain secure.

🌐

DNS Leak Protection

Built-in DNS leak protection routes all DNS queries through encrypted tunnel, preventing ISP or third-party browsing surveillance.

⚡

Kill Switch

Kill Switch auto-cuts network when VPN disconnects unexpectedly, preventing data transmission in unencrypted state.

✓

Third-Party Audit

KuaiYa's privacy policy and encryption have been audited by Privee and other independent security firms, with reports publicly available.

Encryption Security FAQ

Common questions about KuaiYa encryption

What encryption does KuaiYa use?▼

KuaiYa encryption details:

  1. Data uses AES-256 encryption, the most secure symmetric algorithm used by banks and military
  2. AES-256 has 256-bit keys, theoretically requiring 2^256 operations to crack - practically impossible
  3. Control channel uses RSA-4096 asymmetric encryption for secure key exchange
  4. SHA-384 hash algorithm ensures data integrity during transmission
  5. Each connection generates unique forward-secrecy keys
  6. Encryption implementation is optimized for minimal performance impact
What VPN protocols does KuaiYa support?▼

KuaiYa supported protocols:

  1. WireGuard: Next-gen protocol, only 4000 lines of code, faster connections, lower power consumption
  2. OpenVPN: Open-source, 20+ years proven, supports TCP/UDP modes
  3. IKEv2/IPSec: Microsoft-Cisco joint development, fast reconnection for mobile
  4. L2TP/IPSec: Best compatibility, works on almost all devices
  5. Shadowsocks: Lightweight proxy for quick node switching
  6. KuaiYa defaults to WireGuard, users can switch in settings
Does KuaiYa encryption affect speed?▼

KuaiYa performance optimization:

  1. Hardware-accelerated AES using CPU AES-NI instructions, near-native speed
  2. WireGuard reduces encryption overhead by 30% vs OpenVPN, 40% faster
  3. Real-world tests show speed loss under 5%, barely noticeable
  4. Optimized packet encapsulation reduces protocol overhead
  5. Server-side multi-core parallel processing supports 10Gbps per node
  6. For browsing and video, encryption adds less than 1ms latency
How does KuaiYa protect DNS privacy?▼

KuaiYa DNS protection:

  1. Built-in DNS leak protection forces all queries through VPN tunnel
  2. Uses encrypted DNS (DoH/DoT) to prevent middleman eavesdropping
  3. KuaiYa's DNS servers don't log queries, deleted immediately after
  4. WebRTC leak prevention blocks real IP exposure
  5. IPv6 leak protection disables or routes IPv6 through tunnel
  6. Regular leak testing ensures protection in all network conditions
What is KuaiYa's Kill Switch?▼

KuaiYa Kill Switch feature:

  1. Kill Switch auto-cuts network when VPN disconnects unexpectedly
  2. Immediately blocks all traffic when tunnel interruption detected
  3. System-level Kill Switch blocks at OS level, even if apps try direct connection
  4. App-level Kill Switch targets specific apps like browsers, email clients
  5. Network auto-restores when VPN reconnects, no manual action needed
  6. KuaiYa recommends enabling this, especially on public WiFi
Is KuaiYa encryption audited?▼

KuaiYa security audits:

  1. Privacy policy audited by Privee, confirming no activity logging
  2. Encryption implementation audited by Cure53, no vulnerabilities found
  3. Full audit reports publicly available on website
  4. KuaiYa commits to annual independent audits
  5. Bug bounty program encourages security researchers to report issues
  6. All findings fixed within deadline and retested for confirmation
