<h3>MD5加密</h3>
请输入要加密的字符串：<input type="text" id="input_keleyi_com" style="250px;"/>
<br />
<span id="Md5Type">
<input id="Md5Type_1" type="radio" name="md5type_keleyi_com" value="1" checked="checked" /><label for="Md5Type_1">32位[大]</label>
<input id="Md5Type_2" type="radio" name="md5type_keleyi_com" value="2" /><label for="Md5Type_2">32位[小]</label>
<input id="Md5Type_3" type="radio" name="md5type_keleyi_com" value="3" /><label for="Md5Type_3">16位[大]</label>
<input id="Md5Type_4" type="radio" name="md5type_keleyi_com" value="4" /><label for="Md5Type_4">16位[小]</label>
</span><input type="button" value="加 密" onclick="javascript:Md5Ajax();" />
