MP-SPDZ uses OpenSSL for secure channels. You can generate the
necessary certificates and keys as follows:
`Scripts/setup-ssl.sh [<number of parties> <SSL_DIR>]`
`Scripts/setup-ssl.sh [<number of parties> <ssl_dir>]`
The programs expect the keys and certificates to be in
`Player-Data/P<i>.key` and `Player-Data/P<i>.pem`, respectively, and
`SSL_DIR/P<i>.key` and `SSL_DIR/P<i>.pem`, respectively, and
the certificates to have the common name `P<i>` for player
`<i>`. Furthermore, the relevant root certificates have to be in
`Player-Data` such that OpenSSL can find them (run `c_rehash
Player-Data`). The script above takes care of all this by generating
`SSL_DIR` such that OpenSSL can find them (run `c_rehash
<ssl_dir>`). The script above takes care of all this by generating
self-signed certificates. Therefore, if you are running the programs
on different hosts you will need to copy the certificate files.
Note that `<ssl_dir>` must match `SSL_DIR` set in `CONFIG` or `CONFIG.mine`.
Just like `SSL_DIR`, `<ssl_dir>` defaults to `Player-Data`.
In the following, we will walk through running the tutorial modulo
2^k with three parties. The other programs work similarly.
