Quick look-up table to MD5

Generate md5 And the output 16 Base number , Unified java,python,dart Between md5 check

java-spring

System.out.println(org.springframework.util.DigestUtils.md5DigestAsHex("asdf".getBytes()));

public abstract class DigestUtils {
	// A little ... Irrelevant code 
    private static final char[] HEX_CHARS = new char[]{'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};

    // Generate md5 encode  by 16 Base number , abbreviation hex
    private static char[] encodeHex(byte[] bytes) {
        char[] chars = new char[32];

        for(int i = 0; i < chars.length; i += 2) {
            byte b = bytes[i / 2];
            chars[i] = HEX_CHARS[b >>> 4 & 15]; //0xf0 = 15
            chars[i + 1] = HEX_CHARS[b & 15];
        }

        return chars;
    }
}

python

import hashlib

print hashlib.md5("asdf").hexdigest() 

dart

import 'dart:convert';
import "package:crypto/crypto.dart";

var md = md5.convert(utf8.encode('asdf'));
print(md.toString());

Improved version MD5 Generate hexadecimal string
High and low order of bytes
