Question

I have a problem.
I must get a md5 hash of string in Java ME.
I have that code

   public static String md5(String input) throws UnsupportedEncodingException{
    String res = "";
    try {
        MessageDigest algorithm = MessageDigest.getInstance("MD5");
        algorithm.reset();
        algorithm.update(input.getBytes("UTF-8"));
        byte[] md5 = algorithm.digest();
        return md5.toString();
        }
     catch (NoSuchAlgorithmException ex) {}
    return res;
}

But MessageDigest.update() and MessageDigest.digest() accept only 3 arguments.

Any ideas?

Answer 1

The two other arguments are offset and len, which you can set to 0 and the length of the byte buffer respectively.
