Functions

func GenerateSigner

func GenerateSigner() (ed25519.PublicKey, ed25519.PrivateKey, error)

GenerateSigner generates an Ed25519 key pair.

func MnemonicToPrivateKey

func MnemonicToPrivateKey(mnemonic string) (*ecdsa.PrivateKey, error)

func RegisterSigner

func RegisterSigner(privKey *ecdsa.PrivateKey, signer ed25519.PublicKey, fid uint64) (string, chan (uint64), error)

RegisterSigner sends a request to WarpCast API and returns the deep link URL to send to the user. It also returns a channel, which will be used to notify when signer registration is processed. The channel will return the FID of the user.

func SignData

func SignData(privateKey ed25519.PrivateKey, data []byte) (signature []byte, err error)

SignData signs the data using the private key.
