AesCbc class

Implementação de AES-CBC (NIST SP 800-38A) com padding PKCS#7.

⚠️ CBC não é autenticado — considere AES-GCM para AEAD.

final cbc = AesCbc(key: key32, iv: iv16);
final payload = cbc.encrypt(utf8.encode('dados'));
final texto  = utf8.decode(cbc.decrypt(payload));

Constructors

AesCbc({required Uint8List key, required Uint8List iv})
Cria uma instância de AES-CBC com a key e o iv informados.
