This command will generate a config file in location config/config.yaml
Start PSI server:
PSI_CONFIG=<CONFIG> psi_run server <address>
The <CONFIG> means server config file location, and <address> means PSI client address.
Start PSI client:
PSI_CONFIG=<CONFIG> psi_run client <address>
The <CONFIG> means client config file location, and <address> means PSI server address.
Run these two commands:
PSI_CONFIG=config/server.config.yaml psi_run server 127.0.0.1:2345
PSI_CONFIG=config/client.config.yaml psi_run client 127.0.0.1:1234
to start the demo.
For PSI server, the config file is in config/server.config.yaml, the input data file is in server_data.txt and the output result file is in server_result.txt.
For PSI client, the config file is in config/client.config.yaml, the input data file is in client_data.txt and the output result file is in client_result.txt.
