Functions

func CommitsToBytes

func CommitsToBytes(cs []kyber.Point) []byte

func Contains

func Contains(s []*rsa.PrivateKey, i int) bool

func GetDisjointNewOperators

func GetDisjointNewOperators(oldOperators, newOperators []*wire.Operator) []*wire.Operator

GetDisjointNewOperators returns a new set of operators disjoint from old set For example: old set [1,2,3,4,5]; new set [3,4,5,6,7]; returns [6,7]

func GetDisjointOldOperators

func GetDisjointOldOperators(oldOperators, newOperators []*wire.Operator) []*wire.Operator

GetDisjointOldOperators returns an old set of operators disjoint from new set For example: old set [1,2,3,4,5]; new set [3,4,5,6,7]; returns [3,4,5]

func GetNetworkByFork

func GetNetworkByFork(fork [4]byte) eth2_key_manager_core.Network

GetNetworkByFork translates the network fork bytes into name

TODO: once eth2_key_manager implements this we can get rid of it and support all networks ekm supports automatically

func GetNonce

func GetNonce(input []byte) []byte

GetNonce returns a suitable nonce to feed in the DKG config.

func GetThreshold

func GetThreshold(ids []uint64) (int, error)

GetThreshold computes threshold from amount of operators following 3f+1 tolerance

func HexToAddress

func HexToAddress(s string) (common.Address, error)

HexToAddress converts a string HEX representation of Ethereum address to Address structure

func JoinSets

func JoinSets(oldOperators, newOperators []*wire.Operator) []*wire.Operator

JoinSets creates a set of two groups of operators. For example: [1,2,3,4] and [1,2,5,6,7] will return [1,2,3,4,5,6,7]

func SplitBytes

func SplitBytes(buf []byte, lim int) [][]byte

SplitBytes split bytes slice to n parts

func WriteErrorResponse

func WriteErrorResponse(logger *zap.Logger, writer http.ResponseWriter, err error, statusCode int)

func WriteJSON

func WriteJSON(filePth string, data any) error

WriteJSON writes data to JSON file
