Functions

func DeserializeECDSASecp256k1Signature

func DeserializeECDSASecp256k1Signature(sigStr []byte) (*crypto.MPCECDSASignature, error)

- The R and S values must be in the valid range for secp256k1 scalars:

• Negative values are rejected
• Zero is rejected
• Values greater than or equal to the secp256k1 group order are rejected

func Keygen

func Keygen(current crypto.PartyID, option ...KeygenOption) ([]*cmp.Config, error)

Keygen Generates a new ECDSA private key shared among all the given participants.

func SerializeECDSASecp256k1Signature

func SerializeECDSASecp256k1Signature(sig *crypto.MPCECDSASignature) ([]byte, error)

SerializeECDSASecp256k1Signature marshals an ECDSA signature to DER format for use with the CMP protocol

func SignCMP

func SignCMP(configs []*cmp.Config, m []byte) ([]byte, error)

SignCMP signs a message with the given private key using the CMP protocol.

func VerifyCMP

func VerifyCMP(config *cmp.Config, m []byte, sig []byte) (bool, error)

VerifyCMP verifies a message with the given public key using the CMP protocol.
