How to use

• Create KeyPair

keyPair := lazyxsalsa.NewKeyPair()

• Key Exchange

clientKp := lazyxsalsa.NewKeyPair()
serverKp := lazyxsalsa.NewKeyPair()
clientSharedKey := clientKp.Exchange(serverKp.Pk)
serverSharedKey := serverKp.Exchange(clientKp.Pk)

• Encrypt

lazyXsalsa := lazyxsalsa.New()

plaintext := `Plaintext`
ciphertext, err := lazyXsalsa.Encrypt(plaintext, clientSharedKey)

• Decrypt

lazyXsalsa := lazyxsalsa.New()

ciphertext := "ae76477791140129a083a09ff68d5b10460f125c9affdefff48d52d30d774a7c3f42f364ea581eb9b114a65cdbf535171a"
plaintext, err := lazyXsalsa.Decrypt(ciphertext, serverSharedKey)
