一直想要md5那种加密等长，又能解密的对称加密解密方法，于是有了md6。
第一步，去OT扣来think_encrypt和think_decrypt函数。
第二步，打造自己的md6：function md6($str='',$de=false){<br>
$key=('yourkey');<br>
$char=('MDAwMDAwMDAwM');<br>
if($str!=''){ <br>
if($de){<br>
$str=$char.$str;<br>
$str=think_decrypt($str,$key);<br>
}else{<br>
$str=think_encrypt($str,$key);<br>
$str=str_replace($char, '',$str);<br>
}<br>
}<br>
return $str;<br>
}用法举例：function test(){<br>
$str= '';<br>
for($i=1;$i
$str=md6($i);<br>
echo($str.' | '.md6($str,true).'<br>');<br>
}<br>
}输出结果：IKKdXY | 1<br>
IKgdXY | 2<br>
IKwdXY | 3<br>
IN6dXY | 4<br>
IOKdXY | 5<br>
IOgdXY | 6<br>
IOwdXY | 7<br>
IR6dXY | 8<br>
ISKdXY | 9<br>
IKNeXY | 10 <br>

4-6位数（数字和英文）加密后的密文长度为：11，
7-9位数（数字和英文）加密后的密文长度为：17，
在一定范围内加密出来的密文是等长的，有什么作用就自己去发挥吧，我只能帮到这里了！
