c#如何获取密码强度
在c# 源代码里面用 java script
代码如下
<script language=javascript>
//CharMode函数
//测试某个字符是币安机器人源码属于哪一类.
function CharMode(iN){
if (iN>= && iN <=) //数字
return 1;
if (iN>= && iN <=) //大写字母
return 2;
if (iN>= && iN <=) //小写
return 4;
else
return 8; //特殊字符
}
//bitTotal函数
//计算出当前密码当中一共有多少种模式
function bitTotal(num){
modes=0;
for (i=0;i<4;i++){
if (num & 1) modes++;
num>>>=1;
}
return modes;
}
//checkStrong函数
//返回密码的强度级别
function checkStrong(sPW){
if (sPW.length<=4)
return 0; //密码太短
Modes=0;
for (i=0;i<sPW.length;i++){
//测试每一个字符的类别并统计一共有多少种模式.
Modes|=CharMode(sPW.charCodeAt(i));
}
return bitTotal(Modes);
}
//pwStrength函数
//当用户放开键盘或密码输入框失去焦点时,根据不同的级别显示不同的颜色
function pwStrength(pwd){
O_color="#eeeeee";
L_color="#FF";
M_color="#FF";
H_color="#CC";
if (pwd==null||pwd==''){
Lcolor=Mcolor=Hcolor=O_color;
}
else{
S_level=checkStrong(pwd);
switch(S_level) {
case 0:
Lcolor=Mcolor=Hcolor=O_color;
case 1:
Lcolor=L_color;
Mcolor=Hcolor=O_color;
break;
case 2:
Lcolor=Mcolor=M_color;
Hcolor=O_color;
break;
default:
Lcolor=Mcolor=Hcolor=H_color;
}
}
document.getElementById("strength_L").style.background=Lcolor;
document.getElementById("strength_M").style.background=Mcolor;
document.getElementById("strength_H").style.background=Hcolor;
return;
}
</script>
<form name=form1 action="" >
输入密码:
<input type=password size= onkeyup=pwStrength(this.value)
onblur=pwStrength(this.value)>
<br>密码强度:
<table width="" cellspacing="0" cellpadding="1" bordercolor="#cccccc"
height="" style='display:inline'>
<tr align="center" bgcolor="#eeeeee">
<td width="%" id="strength_L">弱</td>
<td width="%" id="strength_M">中</td>
<td width="%" id="strength_H">强</td>
</tr>
</table>
</form>
