🔐 Security-Critical Applications

Cryptographic Key Management System

// Manual implementation for security-critical code
use aes_gcm::{Aes256Gcm, Key, Nonce};
use aes_gcm::aead::{Aead, NewAead};

pub struct SecureKeyManager {
    master_key: Key<Aes256Gcm>,
    key_store: HashMap<String, EncryptedKey>,
}

impl SecureKeyManager {
    pub fn new(master_key: [u8; 32]) -> Result<Self, KeyError> {
        // Manual implementation ensures no AI interpretation
        let key = Key::from_slice(&master_key);
        Ok(SecureKeyManager {
            master_key: *key,
            key_store: HashMap::new(),
        })
    }
    
    pub fn encrypt_key(&self, key_id: &str, plaintext_key: &[u8]) -> Result<(), KeyError> {
        // Every line written manually for security audit
        let cipher = Aes256Gcm::new(&self.master_key);
        let nonce = Nonce::from_slice(b"unique nonce");
        
        let ciphertext = cipher.encrypt(nonce, plaintext_key)
            .map_err(|_| KeyError::EncryptionFailed)?;
            
        self.key_store.insert(key_id.to_string(), EncryptedKey {
            ciphertext,

        require(msg.value > 0, "Deposit amount must be positive");
        
        balances[msg.sender] += msg.value;
        totalLiquidity += msg.value;
        
        emit Deposit(msg.sender, msg.value);
    }
    
    function borrow(uint256 amount) external {
        require(amount > 0, "Borrow amount must be positive");
        require(amount <= totalLiquidity, "Insufficient liquidity");
        require(balances[msg.sender] >= amount * 2, "Insufficient collateral");
        
        borrows[msg.sender] += amount;
        totalLiquidity -= amount;
        
        payable(msg.sender).transfer(amount);
        emit Borrow(msg.sender, amount);
    }
}

🔄 Hybrid Mode: Best of Both Worlds

For projects requiring both speed and precision, with context-aware mode switching.

🏥 Healthcare Application

Patient Management System

// Security-critical authentication (Manual Mode)
class SecureAuth {

        const salt = crypto.randomBytes(32);
        const hash = crypto.pbkdf2Sync(password, salt, 100000, 64, 'sha512');
        
        return this.verifyHash(username, hash, salt);
    }

// API Integration (Hybrid Mode)
// Manual security + AI-generated boilerplate
class PatientAPI {
    // Manual security implementation
    private validateAccess(user: User, patientId: string): boolean {
        return user.role === 'doctor' || user.patientId === patientId;

🌟 Cross-Mode Success Stories

Vibe Mode Success

"I built a complete e-commerce platform in 3 hours. The AI understood my vision perfectly and created exactly what I imagined - beautiful UI, secure backend, and payment processing."

Manual Mode Success

"I implemented a zero-knowledge proof system manually. Every line was written with security in mind, and I understood every cryptographic operation. The manual approach gave me complete confidence in the security."

Hybrid Mode Success

"Our team built a healthcare app using hybrid mode. Security-critical authentication was manual, UI components were AI-generated, and the integration layer used both approaches. Perfect balance of speed and precision."
