html+JavaScript代码:
<html> <head> <script src="./hmac-sha1.js"></script> <script type="text/javascript"> function genkey() { var userName=document.getElementById("userName").value; var password=document.getElementById("password").value; var hash = CryptoJS.HmacSHA1(userName, password); document.getElementById("key").value=hash; }; </script> </head> <body> 用户名:<input id="userName" value="" type="text"> 密码:<input id="password" value="" type="text"><br> 40位字符key:<input id="key" value="" type="text" style="width:400px"><br> <input id="genKey" value="生成key" type="button" onclick="genkey()"> </body> </html>
java 和 javascript CryptoJS 进行HmacSHA1加密
