Functions

func NewLocalParty 

func NewLocalParty(
	msg *big.Int,
	params *tss.Parameters,
	key keygen.LocalPartySaveData,
	out chan<- tss.Message,
	end chan<- *common.SignatureData,
	fullBytesLen ...int) tss.Party

func NewLocalPartyWithAutoKDD added in v2.1.2 

func NewLocalPartyWithAutoKDD(
	msg *big.Int,
	params *tss.Parameters,
	key keygen.LocalPartySaveData,
	keyDerivationDelta *big.Int,
	out chan<- tss.Message,
	end chan<- *common.SignatureData,
	fullBytesLen ...int,
) tss.Party

NewLocalPartyWithAutoKDD returns a party with key derivation delta for HD support for a given unmodified master key. BigXj and ECDSAPub will be multiplied by the computed deltaG value transparently and any error will be returned as a tss.ErrorParty, so that this method can be used as a drop-in replacement to NewLocalParty.

NewLocalPartyWithKDD keeps its original behavior of running the process without performing the initial multiplication in order to not break anyone using or switching to this lib.

func NewLocalPartyWithKDD 

func NewLocalPartyWithKDD(
	msg *big.Int,
	params *tss.Parameters,
	key keygen.LocalPartySaveData,
	keyDerivationDelta *big.Int,
	out chan<- tss.Message,
	end chan<- *common.SignatureData,
	fullBytesLen ...int,
) tss.Party

NewLocalPartyWithKDD returns a party with key derivation delta for HD support
