Review Comment:
```
// Key must be 16, 24 or 32 bytes in length. Thus there could be up to
three
// types of meta_encryptors and data_encryptors.
std::unique_ptr<encryption::AesEncryptor> meta_encryptor_[3];
std::unique_ptr<encryption::AesEncryptor> data_encryptor_[3];
```
And from the comment it might be nullptr
