> Components: C++, Parquet
> Affects Versions: 7.0.0
> Reporter: Antoine Pitrou
> Priority: Critical
> Fix For: 9.0.0
>
>
> {{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.
