JAVA MD5转JS MD5加密

public class md5 {

public static String getMd5(String plainText) {  
    try {  
        MessageDigest md = MessageDigest.getInstance("MD5");  
        md.update(plainText.getBytes());  
        byte b[] = md.digest();  
        md.reset();
        b = md.digest(b);//主要的一步，注释掉这一步就是正常的MD5加密
        int i;  

        StringBuffer buf = new StringBuffer("");  
        for (int offset = 0; offset < b.length; offset++) {  
            i = b[offset];  
            if (i < 0){
                i += 256;  
            }  
            if (i < 16){
                buf.append("0"); 
            }  
            buf.append(Integer.toHexString(i));  
        }  
        //32位加密  
        return buf.toString();  
        // 16位的加密  
        //return buf.toString().substring(8, 24);  
    } catch (NoSuchAlgorithmException e) {  
        e.printStackTrace();  
        return null;  
    }
}

public static void main(String[] args) {
    System.out.println(getMd5("123456"));
}

}

得到的结果是：4280d89a5a03f812751f504cc10ee8a5

这个加密方法怎么用js实现？？？

主要的是 b = md.digest(b);这个方法，不加入这个方法就是正常的MD5加密了，领导说这是md5再加密，js的md5并没有找到此类的方法，所以求大神指点一下，感激不尽了。

没法把java这边改成正常的md5加密么

既然是md5再加密，你前端用两次加密是不是就好了，哈哈哈哈

为什么要用就是呢？难道不能直接用js的ajax调用Java方法吗？

那就只能像楼上说的ajax调用了，或者说去扒一下源码，看看能不能把这个java静态方法js化。

var password = document.forms[0].password.value;
document.forms[0].password.value = hex_md5(password);

忘了贴js了你试试

var mask = (1 << chrsz) - 1;
for(var i = 0; i < str.length * chrsz; i += chrsz)
bin[i>>5] |= (str.charCodeAt(i / chrsz) & mask) << (i%32);
return bin;
}

function binl2hex(binarray)
{
var hex_tab = hexcase ? "0123456789ABCDEF" : "0123456789abcdef";
var str = "";
for(var i = 0; i < binarray.length * 4; i++)
{
str += hex_tab.charAt((binarray[i>>2] >> ((i%4)*8+4)) & 0xF) +
hex_tab.charAt((binarray[i>>2] >> ((i%4)*8 )) & 0xF);
}
return str;
}

已经解决了，下面列出解决方案：
var pswMd5 = md5.digest("123456");
pswMd5 = md5.digest(pswMd5);
var hexValue = "";

for(var i=0;i<pswMd5.length;i++){

var val = pswMd5[i] & 0xff;

if(val<16){

hexValue = hexValue+"0";

}

hexValue = hexValue+val.toString(16);;

}
