"WebSep 10, 2024 · Symmetric Encryption 🔗. Symmetric encryption, or more specifically AES-256, is believed to be quantum-resistant. That means that quantum computers are not expected to be able to reduce the attack time enough to be effective if the key sizes are large enough. Grover’s algorithm can reduce the brute force attack time to its square root. " - Cracking aes 256
