// Enhanced Password Generation with Cryptographic Security function generateSecurePassword(length = 32) { const charset = { uppercase: 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', lowercase: 'abcdefghijklmnopqrstuvwxyz', numbers: '0123456789', symbols: '!@#$%^&*()_+-=[]{}|;:,.<>?' };// Use cryptographically secure random number generation const crypto = window.crypto || window.msCrypto; const array = new Uint32Array(length); crypto.getRandomValues(array); const allChars = Object.values(charset).join(''); return Array.from(array, x => allChars[x % allChars.length]).join('');}
// Implement PBKDF2 key derivation for enhanced security
async function deriveEncryptionKey(password, salt) {
const encoder = new TextEncoder();
const keyMaterial = await crypto.subtle.importKey(
‘raw’,
encoder.encode(password),
‘PBKDF2’,
false,
[‘deriveBits’, ‘deriveKey’]
);return crypto.subtle.deriveKey( { name: 'PBKDF2', salt: encoder.encode(salt), iterations: 100000, hash: 'SHA-256' }, keyMaterial, { name: 'AES-GCM', length: 256 }, false, ['encrypt', 'decrypt'] );}

AES-256 Implementation Best Practices
# Production-Ready AES-256 Encryption
from cryptography.fernet import Fernet
from cryptography.hazmat.primitives import hashes
from cryptography.hazmat.primitives.kdf.pbkdf2 import PBKDF2HMAC
import os, base64
class MilitaryGradeEncryption:
def init(self, password: str):
salt = os.urandom(16)
kdf = PBKDF2HMAC(
algorithm=hashes.SHA256(),
length=32,
salt=salt,
iterations=100000,
)
key = base64.urlsafe_b64encode(kdf.derive(password.encode()))
self.cipher_suite = Fernet(key)
self.salt = salt
def encrypt(self, data: str) -> bytes:
return self.cipher_suite.encrypt(data.encode())
def decrypt(self, encrypted_data: bytes) -> str:
return self.cipher_suite.decrypt(encrypted_data).decode()</code>
Secure Hashing Algorithms
SHA-256: Minimum standard for data integrity
SHA-3: Quantum-resistant hashing for future-proofing
Argon2id: Best practice for password hashing
BLAKE3: High-performance cryptographic hashing
Critical Security Mistakes to Avoid
Mistake 1: Scanning QR codes without verification
Mistake 2: Using weak password generation algorithms
Mistake 3: Ignoring multi-factor authentication
Mistake 4: Storing passwords in plain text
Mistake 5: Falling for clickjacking attacks through malicious QR codes
