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. WebPureVPN uses state-of-the-art AES 256-bit encryption symmetric keys to protect users’ sensitive data so that no government, agencies, or hackers can snoop into the data. Even if someone wants to brute force, it will take 13.8 billion years to crack. Experience this bank-grade encryption to claim your online anonymity and secure your data for ...

"WebMethod. Although we use a 256-bit AES key, we are generating it from a password, so the number of keys possible is limited. In the following code we generate the keys for 'napier','test','password','foxtrot','123456' and 'qwerty', and try these. If the decryption process creates an exception or it unprintable, we ignore it. " - Cracking aes 256
