java代码生成md5	

public void testMD4() {
		try {
			MessageDigest digest = MessageDigest.getInstance("MD5");
			byte[] b = digest.digest("123456".getBytes("UTF-8"));
			StringBuilder sb = new StringBuilder();
			for (byte bt : b) {
				int ibt = bt & 0xff;//抹掉高位
				if (ibt < 16) {
					sb.append(0);
				}
				sb.append(Integer.toHexString(ibt));
			}
			
			System.out.println(sb.toString());

		} catch (Exception e) {
			e.printStackTrace();
		}
	}

golang服务器端生成md5

package main

import (
	"crypto/md5"
	"fmt"
	"io"
)

func main() {

	h := md5.New()

	//向h中写入种子
	seed := "123456"
	io.WriteString(h,seed)

	fmt.Println("golang生成的加密后的byte数组---->",h.Sum(nil))
	//生成唯一字符串
	str := fmt.Sprintf("%x",h.Sum(nil))
	fmt.Println("golang生成的加密后的字符串---->",str)

}
