Crypt rc4
WebNov 27, 2013 · RC4 is a byte-oriented algorithm. Java characters are not bytes. But you can convert strings to and from byte arrays as needed. You're welcome to check out my implementation here. For the conversion to a string with UTF-8 encoding: new String (bytes, "UTF-8"); and to a byte array: str.getBytes ("UTF-8");
