> {{InternalFileDecryptor::WipeOutDecryptionKeys()}} merely call {{std::string::clear}} to dispose of the decryption key contents, but that method is not guaranteed to clear memory (it probably doesn't, actually).
> We should probably devise a portable wrapper function for the various OS-specific memory clearing utilities.
