issue on how to export more data on spdz2k protocol #1496

Hi @mkskeller, I'm trying to export data on spdz2k protocol. I use "write_to_file()" to export the share of secret and the MAC. but how can I export other data like the share of beaver used in protocol and the share of MAC keys and the MAC parameter?

There is no general functionality to access Beaver triples. This is because they are only to be used once. If you use online-only benchmarking however, you can see the triples in Player-Data/<no of parties>-Z<K>-,<S>-<K>/Triples-Z<K>,<S>-<K>-P<party number> where <K> and <S> denote the SPDZ2k parameters. Similarly , Player-MAC-Keys-R-P<party number> in the same directory contains the MAC keys.
