encryptUint8List static method
AES-256-CBC/PKCS7 with UTF-8 key (32 chars) and IV (16 chars).
Implementation
static String encryptUint8List({required Uint8List data, required String key, required String iv}) {
if (key.length != 32) throw ArgumentError("Key must be 32 bytes for AES-256.");
if (iv.length != 16) throw ArgumentError("IV must be 16 bytes for AES.");
return base64.encode(_aesCbc(_u8(key), _u8(iv), data, true, true));
}
