信息加密

MD5、SHA 加密方式:

import java.security.*;

public class demo {

    public static void main(String[] args) throws NoSuchAlgorithmException {
        String name = "hero";
        String password = "666666";
        MessageDigest md = MessageDigest.getInstance("MD5");
        md.update(name.getBytes());
        md.update(password.getBytes());

        byte[] b = md.digest();
        String hs="",stmp ="";

        for (int i = 0;i < b.length;i++) {//二行制转字符串
            stmp=(Integer.toHexString(b[i] & 0XFF));
            if (stmp.length()==1) hs=hs+"0"+stmp;
            else hs=hs+stmp;
        }
        System.out.println(hs.toUpperCase());
    }

  }
