AES-256 Encryption: What It Is and Why It Matters

AES-256 is a symmetric encryption cipher used by governments, militaries, and AstraGuardVPN to secure data with a 256-bit key that would take billions of years to crack by brute force.

Includes AES-256 encryption, a kill switch, and DNS leak protection.

Steps

  1. What is AES-256? — AES-256 (Advanced Encryption Standard with 256-bit keys) is the strongest widely deployed symmetric encryption standard, used for highly sensitive data.
  2. How AstraGuard uses it — AstraGuard applies AES-256 to encrypt traffic between your device and VPN servers, making intercepted data unreadable.
  3. Why it is considered strong — Brute-forcing AES-256 is computationally infeasible with current technology, which is why it is trusted for government and enterprise security.
