How to encrypt String?

[EuphoriaCelestial]

I ran the example code inside the folder. It worked well, but only able to encrypt natural number from 0 to 255, any number bigger will result incorrect, and most of all, I cant encrypt String type.
I tried to change data type of input, output array to String and else, but none is work.
Anyone still here to help?

To encrypt and decrypt String, I made helper functions using String.getBytes() method
`void StringToHexArray(String input, byte * target, int length) {
input.getBytes(target, length + 1);//extra length for terminating character
}

String HexArrayToString(int length) {
String output = "";
for (int i = 0; i < length; i++) {
output += String((char)out[i]);
}
return output;
}`
