Functions

func ReceiverChoose

func ReceiverChoose(receiverPrivateKey *ecdsa.PrivateKey, senderPublicKey *ecdsa.PublicKey, chosenIndex int) (*ecdsa.PublicKey, error)

ReceiverChoose 接收方Bob选择需要哪份数据，也就是做1 of 2选择

func ReceiverRetrieveMsg

func ReceiverRetrieveMsg(receiverPrivateKey *ecdsa.PrivateKey, senderPublicKey *ecdsa.PublicKey, cts []string, chosenIndex int) (string, error)

ReceiverRetrieveMsg Bob根据之前的选择结果，解密并获取自己需要的数据

func SenderEncryptMsg

func SenderEncryptMsg(senderPrivateKey *ecdsa.PrivateKey, receiverPublicKey *ecdsa.PublicKey, msgs []string) ([]string, error)

SenderEncryptMsg 发送方Alice根据接收方Bob发来的公钥，做进一步计算
