MD5 Hashing Algorithm in Java

A Simple Java Program to Convert a String into MD5 Hashing.

import java.nio.charset.StandardCharsets;

import java.util.Scanner;

public class MD5Encryption {

	public static void main(String[] args) throws NoSuchAlgorithmException {
		Scanner sc = new Scanner(System.in);
		String val = sc.next();
		MessageDigest digest = MessageDigest.getInstance("MD5");
		byte[] encodedHash = digest.digest(val.getBytes(StandardCharsets.UTF_8));
		StringBuffer md5EncodedString = bytestoHexString(encodedHash);
		System.out.println(md5EncodedString);
	}

	private static StringBuffer bytestoHexString(byte[] encodedHash) {
		StringBuffer hexString = new StringBuffer();
		for (int i = 0; i < encodedHash.length; i++) {
			String hex = Integer.toHexString(0xff & encodedHash[i]);
			if (hex.length() == 0)
				hexString.append("0");
			hexString.append(hex);
