Struct EncryptionEngine 

pub struct EncryptionEngine { /* private fields */ }

Encryption engine using AES-256-GCM SECURITY: Uses atomic counter to guarantee nonce uniqueness

Implementations

impl EncryptionEngine

pub fn new(key: &EncryptionKey) -> Result<Self, String>

Create new encryption engine with key

pub fn encrypt(&self, plaintext: &[u8]) -> Result<Vec<u8>, String>

Encrypt data with authenticated encryption (AES-256-GCM)

Format: [version: 1 byte][nonce: 12 bytes][ciphertext + auth tag] SECURITY: Uses counter-based nonce to guarantee uniqueness

pub fn decrypt(&self, encrypted: &[u8]) -> Result<Vec<u8>, String>

Decrypt data with authentication verification
