func NewDGRound4Message added in v1.1.0 

func NewDGRound4Message(

func NewLocalParty 

func NewLocalParty(
	params *tss.ReSharingParameters,
	key keygen.LocalPartySaveData,
	out chan<- tss.Message,
	end chan<- keygen.LocalPartySaveData,
) tss.Party

Exported, used in `tss` client The `key` is read from and/or written to depending on whether this party is part of the old or the new committee. You may optionally generate and set the LocalPreParams if you would like to use pre-generated safe primes and Paillier secret. (This is similar to providing the `optionalPreParams` to `keygen.LocalParty`).
