Functions ¶

func BytesToHashString ¶

func BytesToHashString(msg []byte) (string, error)

func CheckKeyOnCurve ¶

func CheckKeyOnCurve(pkData []byte) (bool, error)

CheckKeyOnCurve check if a SECP256K1 public key is on the elliptic curve

func CheckUnicast ¶

func CheckUnicast(round RoundInfo) bool

due to the nature of tss, we may find the invalid share of the previous round only when we get the shares from the peers in the current round. So, when we identify an error in this round, we check whether the previous round is the unicast

func GenerateSignature ¶

func GenerateSignature(msg []byte, msgID string, privKey crypto.PrivKey) ([]byte, error)

func GetBroadcastMessageType ¶

func GetBroadcastMessageType(msgType message.TssMsgType) message.TssMsgType

GetBroadcastMessageType gets the broadcast message type of the message

func GetECDSAPubKeyFromPubKeyData ¶

func GetECDSAPubKeyFromPubKeyData(pkData []byte) (*ecdsa.PublicKey, error)

pkData -> ecdsa.PublicKey

func GetPIDFromPartyID ¶

func GetPIDFromPartyID(partyID *btss.PartyID) (peer.ID, error)

partyID -> pid

func GetPIDFromPubKey ¶

func GetPIDFromPubKey(pk crypto.PubKey) (peer.ID, error)

pubkey -> peer.ID

func GetPIDFromPubKeyData ¶

func GetPIDFromPubKeyData(pk []byte) (peer.ID, error)

[]pkData -> []peer.ID

func GetParties ¶

func GetParties(keys []crypto.PubKey, localPK crypto.PubKey, peerMap map[string]*peer.AddrInfo) ([]*btss.PartyID, *btss.PartyID, error)

GetParties get parties and localParty according the parties pubkey and peersInfo. PeersInfo is needed to match the partyid.id with the serial number ID of the P2P Peer. []pubkeys, pubkey, peersInfo -> []partyIDs, partyID

func GetPatyIDInfoMap ¶

func GetPatyIDInfoMap(partiesID []*btss.PartyID) (map[string]*btss.PartyID, error)

GetPreviousKeySignUicast eets the last unicast message for the current message

func GetPubKeyDataFromPartyID ¶

func GetPubKeyDataFromPartyID(partyID *btss.PartyID) ([]byte, error)

partyID -> pubkeyData

func GetPubKeyDatasFromPartyIDs ¶

func GetPubKeyDatasFromPartyIDs(partyIDs []*btss.PartyID) ([][]byte, error)

[]partyID -> []pubkeyData

func GetPubKeyDatasMapFromPartyIDs ¶

func GetPubKeyDatasMapFromPartyIDs(partyIDs []*btss.PartyID) (map[string][]byte, error)

[]partyID -> map[partyID.id][pubkeyData]

func GetPubKeyFromPartyID ¶

func GetPubKeyFromPartyID(partyID *btss.PartyID) (crypto.PubKey, error)

partyID -> pubkey

func GetPubKeyFromPubKeyData ¶

ECPoint -> ecdsa.PublicKey

func MsgToHashInt ¶

func MsgToHashInt(msg []byte) (*big.Int, error)

func MsgToHashString ¶

func MsgToHashString(msg []byte) (string, error)

func SortPubKey ¶

func SortPubKey(keys []crypto.PubKey)

func VerifySignature ¶

func VerifySignature(pubKey crypto.PubKey, message, sig []byte, msgID string) (bool, error)

Types ¶

type PartyInfo ¶

type PartyInfo struct {
	// Message identifier -> localParty of the message
	// - only one in keygen
	// - maybe some in keysign. Each message to be signed corresponds to a corresponding current participant
	PartyMap *sync.Map
	// partyID.id -> partyID
	PartyIDMap map[string]*btss.PartyID
}

PartyInfo the information used by tss key gen and key sign
