It seems decrytion cannot deal with encrypted empty string

[johnnyp1883]

Hi I found the decryption cannot handle the empty string
It returns error "invalid length of message"
Is it possible to allow empty string in the future?

func TestEncryptAndDecrypt(t *testing.T) {
	privkey, err :=  GenerateKey()
	if !assert.NoError(t, err) {
		return
	}

	testingEmptyStringMessage := ""
	ciphertext, err := Encrypt(privkey.PublicKey, []byte(testingEmptyStringMessage))
	if !assert.NoError(t, err) {
		return
	}

	plaintext, err := Decrypt(privkey, ciphertext)
	if !assert.NoError(t, err) {
		return
	}

	assert.Equal(t, testingMessage, string(plaintext))
}

Can you explain in which case you will need to encrypt empty string?
