type VLPSI

func NewVLPSIByPairs

func NewVLPSIByPairs(name string, samplesFile []byte, samplesIdName string, parties []string) (VLPSI, error)

NewVLPSIByPairs create a VLPSI instance and initiate it, calculating intersections of multiple nodes by pairs. name is to name the PSI instance parties are names of other parties who participate MPC sampleFile is csv file content subjected to specified form sampleIdName is used to extract IDs

func NewVLTwoPartsPSI

func NewVLTwoPartsPSI(name string, samplesFile []byte, samplesIdName string, parties []string) (VLPSI, error)

NewVLTwoPartsPSI create a VLPSI instance and initiate it name is to name the PSI instance parties are names of other parties who participate MPC sampleFile is csv file content subjected to specified form sampleIdName is used to extract IDs
